Temperature records (data)
« on: February 10, 2020, 01:12:43 PM »
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 28th June 2019
  • Belgium: 41.8C in Begijnendijk on 25th July 2019
  • Germany: 42.6C in Lingen on 25th July 2019
  • Luxembourg: 40.8C in Steinsel on 25th July 2019
  • Netherlands: 40.7C in Gilze en Rijen on 25th July 2019
  • United Kingdom: 38.7C in Cambridge on 25th 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 6th February 2020.

Good idea IMHO. :)

Is this a pure data thread, or is it open for discussions too?

Cat 6, the Weather Underground blog, often [e.g., here] features Mr. Herrera's data and frequently identifies his work as the best in the world, as to maintaining and analyzing temperature records.

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.

Winter is December-February here. However, sometimes March or November was colder.

Miami, Florida sets all-time April temperature record earlier today at 97F (~37C). Previous April record was 96F set in 2015.

On May 17th Paphos Airport in Cyprus reached 42.5 C.

Easily broke it's old May record and set a national record for May.

It's located near the coast and this is also the highest temperature ever recorded at the station. Remarkable for it to happen in May.

Copying a post from the melting season here because it fits. Thanks to Rubikscube

Records broken in Longyearbyen, Svalbard and Eureka, Canada
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.

Taipei had 39.7℃ Friday, making it the highest temperature since records began 124 years ago. On the previous day, the southwestern end of Japan's Yonaguni had all-time record high of 35.5℃.

Sunday 16th August 2020 it reached 130 F (54.4C) at Death Valley .

If confirmed this would be hottest reliably measured 2m air temperature ever recorded on earth.

First time for DV to record 130 F since the dodgy readings from 1913.

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".

Death Valley was 114 F at 9am today

Same time yesterday was 107 F.

Will we see a new record max today ?

Low of 101?

120 F at 11am PDT.

Very hot for so early in the day.

However the northerly wind has increase to 9 mph with a gust of 17 mph.

Will the increased mixing scupper the chances of a new record today ? There is still another potential 5 hours of heating to go to break 130 F !

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).

Same heatwave, another day, more records broken...

Heat records dropping left, right and centre.

Hottest September day on record for Belgium 35.4 °C. Long standing records (over 90 years) getting smashed in the Netherlands.

Reminder: we are 2 weeks from October.

Tuesday the 15th of september was the latest ever tropical day (over 30C) in the dutch weather records.

It only happened 5 times before. Last one was 14-09-2016.

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.

Thank you Niall for the clarification. I understood it the same (wrong) way as you described. I have edited my post above to make it more clear. Fact checking is important.
