Author Topic: Temperature records (data) (Read 38973 times)

Hello ASIF, I had this idea for a new thread with the specific purpose of keeping track of temperature records (both high and low). I haven't found a similar existing thread, but if one exists, please just remove this one.

With temperature records tumbling around the globe, I think it would be interesting of having a record (even if very incomplete) where and when new records are set. I think it would be best to limit this thread to purely data posts, and leave away big discussions (like the ASI extent data thread). Also whenever possible it would be good to provide information about the temperature that was measured (in °C or °C/°F), when (date) a record was set, where (weather station / town / country) it was set and what kind of record it is (monthly / all-time / ...). Also a source would be helpful.

To start the thread I'd like to go back to the Europe summer 2019 heatwave(s) were several country-wide all-time records were broken (source):

France: 46.0C in Vérargues on 28^th June 2019
Belgium: 41.8C in Begijnendijk on 25^th July 2019
Germany: 42.6C in Lingen on 25^th July 2019
Luxembourg: 40.8C in Steinsel on 25^th July 2019
Netherlands: 40.7C in Gilze en Rijen on 25^th July 2019
United Kingdom: 38.7C in Cambridge on 25^th July 2019

On a more recent note, it has been reported that the all time high for the whole continent of Antarctica has been broken with 18.3C at the Esperanza Base on 6^th February 2020.

The records that I am most curious about are wet-bulb temperatures and good data about temperature and humidity together. Given their vital importance, I find it a bit strange that accurate values are not easily available.

Very good pietkuip, that would be important data/information.
Where to find humidity data? It isn't stated with a new temperature record. But then again, it is only of interest for temperatures above 35°C/95°F. Not only for records because the temperature may not set a new record but the wet bulb temperature might set a new record. Too bad climatereanalyser doesn't show a wet bulb temperature.

Warmest temperature ever recorded on Svalbard yesterday. 21.7 C that is, and more to come. Previous record temperature for Eureka is 20.9, also looking to fall (the forecast attached says Eureka, N.W.T, but map coordinates show it is Eureka, Nunavut). Link to Canadian gov temperature records from Eureka.

I suspect record melt is ongoing across CAA and much the Atlantic side up to the pole.

What could be the highest temperature ever reliably recorded on Earth - 130F (54.4C) - has been reached in Death Valley National Park in California.
The recording is being verified by the US National Weather Service.
It comes amid a heatwave on the US's west coast, where temperatures are forecast to rise further this week.
The scorching conditions have led to two days of blackouts in California, after a power plant malfunctioned on Saturday.
What were the previous records?
Sunday's reading was recorded in Furnace Creek in Death Valley.
Before this, the hottest temperature reliably recorded on Earth was 129.2F (54C) - also in Death Valley in 2013.
A higher reading of 134F, or 56.6C a century earlier, also in Death Valley, is disputed. It is believed by some modern weather experts to have been erroneous, along with several other searing temperatures recorded that summer.
Dangerous heat wave forecast for south-west US
Summers could become 'too hot for humans'
Last decade confirmed as hottest on record
According to a 2016 analysis from weather historian Christopher Burt, other temperatures in the region recorded in 1913 do not corroborate the Death Valley reading.
Another record temperature for the planet - 131F, or 55C - was recorded in Tunisia in 1931, but Mr Burt said this reading, as well as others recorded in Africa during the colonial era, had "serious credibility issues".

NZ has warmest winter on record..

Quote

Warm winters are becoming a recurring theme in New Zealand.
This year’s winter peaked at 1.14 degrees Celsius above average, making it the warmest on record.
Niwa has been recording seasonal averages for 111 years, but seven of the 10 warmest winters have all occurred in the 21st century. The previous record was made in 2013 when the seasonal average increased by 1.08C.
“That really shows a trend,” NIWA forecaster Ben Noll said.

We have just witnessed the hottest September day in France (on a national level) since records began.

Over 230 monthly station records were broken today alone. Some of these records go back nearly 150 years.

Hotspot today was Orthez at 37.9 °C.

France just recorded the hottest September day (average of max temperature of all stations across the country). Note that the single highest recorded September temperature record hasn't been broken (as Niall has correctly mentioned 2 posts below).

The graphics from Scott Duncan are nice - but misleading.

Both contain the phrase :

"Hottest September Day on record for [insert country name]"

Whereas new national September extreme temperature records were set in Belgium and the Netherlands, this was not the case in France. The September record remains 40 C at Ajaccio in Corsica.

So what Scott was referring to in France was the highest average of a collection of max temperatures across France. This is not usually what people think of, when they hear "hottest on record". In fairness to Scott, he does clarify this difference in the text but the graphic doesn't.

Hi Kassy

I have just copied over your post in the heatwave thread to revive this thread, which I think would be better used to reply to specific temperature records (as opposed to comment on heatwaves in general).

Quote from: kassy on July 14, 2021, 02:16:32 PM

For the second year in a row, Death Valley, California, reached the highest daily average temperature ever observed on Earth (reliably). According to the US National Weather Service, temperatures reached a 130 degrees Fahrenheit (54.4ºC) last Friday, edging the previous record of 129.9 degrees Fahrenheit set on August 16, 2020.

...

The new record was registered at the Stovepipe Wells weather station in the northern part of Death Valley National Park. This is separate from the frequently referenced temperature measurements at Death Valley’s Furnace Creek, located further southeast. The record will now have to be reviewed by the World Meteorological Organization (WMO).
...

Reliable measurements
Still, there are other factors to contemplate that could affect the recent record at Furnace Creek . William Reid, a climatologist expert on Death Valley meteorology, said that an increase in vegetation and structures built in the vicinity of the Furnace Creek site in recent decades has allowed the station to record hotter temperatures.

“An increase in vegetation and some man-made structures not too far south of the station have resulted in poorer ventilation through the station area. Since the station is above a bare and sandy surface, hot air along the ground during afternoon sunshine is less effectively mixed away from the instrumentation. The result is higher temperature readings during the afternoon comparably,” Reid wrote

https://www.zmescience.com/ecology/death-valley-breaks-all-time-world-heat-record-again/

The article from zmescience.com states that the recent temperature of 130 F occured at the US Climate Reference Site (USCRN) at Stovepipe Wells, CA.

I do not believe this is true.

The 130 F last Friday was measured at Furnace Creek, Death Valley.

I have attached a graph of max and min values from Stovepipe Wells so far this month and the highest maximum so far has been 128 F on the 10th and 11th of July.

Perhaps the mix up has occurred because Stovepipe Wells has set a new US record for highest daily low temperature of 108 F on the 11th.

Of course that is nothing at all to do with record daily high values. These occurred at Furnace Creek. I believe a primary reason for the higher maxima at Furnace Creek is because the screen there is not aspirated/ventilated, whereas the screen at Stovepipe Wells is aspirated.

I mentioned before in the other thread that Campbell Scientific have installed another sensor at Furnace Creek and it will be interesting to see what was the temperatures recorded by this device.

July was the hottest month ever recorded, NOAA says

Quote

It's been a summer of sweltering heat waves and raging wildfires, and now it's confirmed: July 2021 was the hottest month on Earth since record-keeping began. The National Oceanic and Atmospheric Administration announced the findings on Friday, calling it an "unenviable distinction" and part of a worsening trend related to climate change.
…
According to data released by NOAA's National Centers for Environmental Information, the average worldwide land and ocean surface temperature in July was 1.67 degrees Fahrenheit hotter than the 20th century average of 60.4 degrees Fahrenheit. Official record-keeping of global temperatures began 142 years ago.

The high temperatures broke records in Asia, which had its hottest July ever recorded. Nine of the 10 warmest Julys in Asia have occurred since 2005, NOAA says.

North America, South America, Africa and Oceania had temperatures making it one of the top 10 warmest Julys on record. Much of the western U.S. grappled with the region's worst heat waves ever, and many states had their warmest July on record, the agency said. …

The data shows that the combined land and ocean-surface temperature was 0.93C (1.68F) above the 20th Century average of 15.8C (60.4F).

It is the highest temperature since record-keeping began 142 years ago. The previous record, set in July 2016, was equalled in 2019 and 2020.

...

The combined land and ocean-surface temperature was 0.01C higher than the 2016 record.

In the Northern Hemisphere, land-surface temperature reached an "unprecedented" 1.54C higher than average, surpassing a previous record set in 2012.

The data also showed that July was Asia's hottest month on record, as well as Europe's second hottest after July 2018.

Climate change: Europe's 2020 heat reached 'troubling' level

Last year was the warmest on record across Europe, breaking the previous high mark by a considerable distance, say scientists.

Temperatures across the region were more than 1.9C above the long-term average between 1981 and 2010.

...

This new data shows that Europe's temperature margin over previous years was significantly greater than previously thought.

Not only was the year 1.9C above the long-term average, it was more than 0.5C greater than the previous high mark.

...

"This level of difference to the previous long-term average, which is a large difference, is something that is concerning," said Dr Robert Dunn, a senior climate scientist at the UK Met Office.

...

"The amount by which the previous record has been exceeded should worry us all," said Prof Gabi Hegerl, professor of climate system science at the University of Edinburgh, who was not involved with the study.

"European temperatures are well measured and can be tracked back to the beginning of industrialisation and beyond, using documentary evidence and proxy records. This long-term context emphasises how unusual this warmth is."

The warmth across Europe brought huge temperature differences from the long-term average in some countries with Estonia, Finland and Latvia all recording anomalies of 2.4C.

....

One other area of the world experiencing rapid warming is the Arctic.

Temperatures over land reached worrying new heights, getting to 2.1C above the 1981-2010 average. This was the highest since the series of records began 121 years ago.

Oymyakon. Long known as the coldest permanently inhabited place on earth has set two date records for minimum temperature this month.

September 10th : -14.8° C
September 12th : -13.1° C.

Hard to know what to make of this, if anything, in a fast changing climate.

The diurnal ranges were large (Max of +14.4° C on the 12th). So likely deep radiational cooling.

This is not all that newsworthy. Sure, breaking 100F (38C) sounds like a major story, but when the previous high was 99F (37.3C), set 32 years prior, it is not much of a difference. This town is notable for the largest temperature swings on earth.

More than 400 weather stations beat heat records in 2021

More than 400 weather stations around the world beat their all-time highest temperature records in 2021, according to a climatologist who has been compiling weather records for over 30 years.

...

Ten national temperature records were broken or equalled in 2021, including the highest ever reliably measured on Earth (see graph at link).

A few continental and planetary records fell too: Africa had its warmest June and September ever. August brought 48.8C (119.8F) in Syracuse, Italy, the highest temperature ever recorded in Europe. July had already brought 54.4C (130F) in Furnace Creek in the US’s Death Valley – the highest reliably recorded temperature on Earth. (A temperature recorded as 129.9F in 2020 was also rounded up to 130F.)

But there were a few specific events that particularly stood out for experts. For meteorologist Patricia Nying’uro, a co-founder of Climate Without Borders and based at the Kenyan Meteorological Department, the two consecutive failed rain seasons in Kenya were unusual, and forced the government to organise for food aid for the first time in many years.

“You can certainly see the effect of climate change in our weather in Kenya, and globally. We’re just putting together the data for 2021, but we think we will have seen an annual temperature which is 2.1C higher than normal for some parts of the country. The shifts are very noticeable, from one extreme to another in a very short space of time.”

...

China experienced its hottest ever year, according to the China Meteorological Administration. But it was the rain that hit the central province of Henan that really shocked: the region was hit by more rain in three days than it normally receives in an entire year.

The Copernicus Climate Change Service said 2021 was the fifth-warmest year, with record-breaking heat in some regions.

...

Fifth-warmest year
Copernicus data showed that 2021 was the fifth-hottest on record, marginally warmer than 2015 and 2018. Taken together, the past seven years were the hottest seven years on record by a clear margin, the agency explained.

The 2021 average temperature was 1.1-1.2C above the pre-industrial level around 150 years ago.

...

The agency said that the start of the year saw relatively low temperatures compared to recent years, but that by June monthly temperatures were at least among the warmest four recorded.

Places with above average temperatures included the west coast of US and Canada, north-east Canada and Greenland, large parts of north and central Africa, and the Middle East.

The weather phenomenon known as La Niña - when surface sea temperatures are cooler - contributed to below-average temperatures in western and eastern Siberia, Alaska, and the central and eastern Pacific during the start and end of 2021.

Britain has seen its hottest New Year's Eve ever with temperatures reaching 15.8C (60.4F) in the west of England, the Met Office has said.

After that BBC report was issued the temperatures continued to rise on New Year's Eve over the west of the UK and Ireland. It is even more unusual to see the temperatures rising during nighttime hours.

The temperature peaked at Bala, Wales at 5am with a maximum of 16.5° C recorded.

Because "day" temperatures have been historically recorded between the hours of 9 UTC to 9 UTC the next day, this 16.5° maximum is logged as the record high max for 31st December (NYE) and was also the highest value recorded for the whole month of December in the UK - even though it actually occured at circa 5am on January 1st 2022 !

Australia matches its hottest day on record as Western Australia town goes above 50C

Mercury in the remote town of Onslow registers 50.7C , while two other sites also reach extreme temperatures

Australia has matched its hottest ever reliably recorded temperature, with Onslow airport near the remote West Australian town of Onslow registering 50.7C.

Prior to Thursday, the 50C-mark had only been crossed three times at a standardised monitoring site including consecutive days in early 1960. Onslow’s top was reached just before 2.30pm local time.

The 50.7C reading on 2 January 1960 had stood unmatched as Australia’s hottest temperature for 62 years, with the following day almost as scorching at 50.3C, according to Bureau of Meteorology data going back nationally to 1910.

On Thursday, Onslow was joined by at least two other WA sites in breaking 50C, with both Roebourne airport and Mardie hitting 50.5C. Mardie had been there once before, on 19 February 1998 – Australia’s only other 50C-plus day among the four.

The extreme temperatures came towards the end of a searing heatwave over north-western WA in recent days.

...

A slew of other WA towns were likely to have set temperature records for January or any time of the year.

Iron-ore export hub Karratha, also on WA’s north-west coast, reached 48.4C to exceed its previous high of 48.2C.

Niwa confirms 2021 was NZ's hottest year on record

Quote

What was New Zealand's costliest year for flood damage was also our warmest – sending a grim reminder, if we still needed one, that our planet is heating at an alarming rate.

Niwa today revealed that 2021 was the hottest year in more than a century of records, with a mean land surface temperature of 13.56C - or just shy of 1C above the 1981-2010 average.

That placed it above our previous warmest, 2016, as well as 2018, which began with a record-hot summer, and 1998, the year a severe El Nino fuelled a nightmare drought.

"Coming up to the end of last year, we knew it was going to be in the top three, but December was such a hot month that it wasn't even by a close margin that it beat 2016," Niwa climate scientist Nava Fedaeff said."It is alarming that we have had so much warmth, particularly in the last decade," she said, noting that seven of the past nine years have been among the hottest on the books.

"Hopefully it does open some people's eyes, if they're not already open – but this isn't anything particularly new. We've been seeing this for a while now."
