Record Warmth in Siberia, Brazil and Cold in U.S. Upper Midwest

In contrast to the continuing near-record cold temperatures in the U.S. Upper Midwest, record warmth has been occurring in portions of Siberia and Brazil. Here are the details.

Record cold continues in upper Midwest

Duluth, Minnesota finally snapped its record longest stretch of 0°F (-17.8°C) or below days today (February 12th) when the temperature this morning fell to ‘only’ 10°F (-12.2°C). For 23 days from January 19th to February 11th the minimum temperature fell to zero or below. This surpassed the previous record of 22 days set in 1936 (January 17-February 7) and also in 1963 (January 10th to January 31st). Lake Superior is now 87.1% iced over, its greatest extent since the winter of 1996 and closing in on the record 94.7% during the winter of 1979.

Chicago fell below zero again Wednesday morning (January 12th) making this the 22nd zero or below day this winter tying 4th place (with the winter of 1981-1982) for the most such on record. Here’s where the ranking stands now:

Meanwhile on the other side of the North Pole in Siberia…

All-time record monthly warm temperatures have been observed at many sites in the Siberian states of Yakutia and Kamchatka. In what is normally the coldest permanently inhabited place on earth, Oymyakon (various spellings), saw its temperature rise to a February record high of -12.5°C (9.5°F) on February 9th (previous record was -15.3°C/4.5°F in February 2010). The normal high temperature at this time of the year should be around -42°C (-51°F). Oymyakon also holds the world record (along with Verkhoyansk) for the coldest temperature ever measured on earth at an inhabited site: -67.7°C (-90°F) set on February 6, 1933 (almost exactly 80 years ago).

Other all-time monthly records have been set at:

Petropavlovsk-Kamchatski: 5.3°C (41.5°F) on Feb. 3 (previous record 5.0°C/41.0°F on Feb. 19, 1986)

Pevek: 5.6°C (42.1°F) on Feb. 8 (previous record 1.4°C/34.5°F on Feb. 28, 2008)

Magadan: 3.2°C (37.8°F) on Feb. 8 (old record 2.5°C/36.5°F in February 1968

Omolon: 2.9°C (37.2°F) on Feb. 7 (old record -0.6°C/30.9°F on Feb. 1, 1985). This is the first time this site has ever risen above freezing during the month of February.

Okhotsk: 2.0°C (35.6°F) on Feb. 7 (old record 1.9°C/35.4°F in February 1985

Keyes: 3.7°C (38.7°F) on Feb. 6 (old record 3.0°C/37.4°F on Feb. 28, 1982).

Record heat wave and drought in Sao Paulo, Brazil

The official weather station for Sao Paulo (Brazil’s largest city) Mirante do Santana has recorded its warmest January on record with a daily average of 25.0°C (previous January record was 24.6°C in 1998) and its maximum average of 31.9°C (89.4°F) was the warmest such for any month surpassing February 1984. This was the 2nd warmest month (any month) on record for average temperature, surpassed only by the 25.4°C of February 2003. Since January the temperatures in Sao Paulo have shot up even higher Here are the daily highs observed so far:

Feb. 1: 35.9°C (96.6°F)
Feb. 2: 34.5°C (94.1°F)
Feb. 3: 35.0°C (95.0°F)
Feb. 4: 34.7°C (94.5°F)
Feb. 5: 35.5°C (95.9°F)
Feb. 6: 35.2°C (95.4°F)
Feb. 7: 36.4°C (97.5°F) (this is just shy of the all-time record of 37.0°/98.6°F set in January 1999)
Feb. 8: 36.3°C (97.3°F)
Feb. 9: 36.1°C (97.0°F)
Feb. 10: 34.7°C (94.5°F)
Feb. 11: 33.3°C (91.9°F)

The normal daily high temperature for both January and February is about 28°C (82°F).

Even hotter temperatures prevailed in other locations in southern Brazil such as the 41.2°C (106.2°F) at Indaial this past week. Unofficial temperatures as high as 42°-43°C (107.6°-109.4°F) have been reported from locations in Rio Grande do Sul and Catarina States. Brazil’s hottest temperature on record remains 44.6°C (112.3°F) at Orleans, Santa Catarina State on January 6, 1963. Sao Paulo’s main reservoir is apparently now less than 25% of its capacity, a ten-year low.

Cooler weather and some rainfall is now on the horizon and expected to bring some relief to both the heat and drought.

Talk about extremes!

Here in Germany (southwest, neat Stuttgart), we are still having a non-winter. Only had one snowfall the entire winter, all of one inch. It lasted about half a day. Temps just refuse to get below freezing. All my years in Germany I have never seen such a mild winter.

I won't complain. You don't have to shovel rain!

Quoting 2. weatherdogg:
I think you mean the average low temp for Omyakon is -48C, not the average high temp. I think the average high is in the mid -30Cs. Still crazy warm for those guys. I bet they are in shirt sleeves.


Yes, that's right.

February average T for Oymyakon:
-47.3C/-35.4C average -42.0C

Adelaide has experienced a record 13 days of 40C-plus maximums this summer after the temperature reached 41.7C at 2.30pm on Wednesday.

Port Pirie experienced the state’s highest temperature recording of 45C at 12.53pm on Wednesday.

Adelaide has already surpassed the record number of days over 42C in a calendar year, previously set at six in both 1939 and 2009.............. While the average maximum temperature in the last 31 days in Adelaide is 36 degrees, some areas of the state have sweltered under even greater maximums.

“Coober Pedy has averaged 40C in February,’’ Mr Lainio added.

“Heat has been sitting in the north of the state for weeks and this is the main reason we (in Adelaide) have returned to above 40C so often,’’.

Last month was the hottest January on record and the state recorded its fourth hottest day in history of 45.1c on January 14.

The five consecutive days above 42C from January 13 to January 17 were also a record.

Coming on the back of the hottest ever year across Australia and South Australia last year — since reliable records were first kept in 1887 — South Australia could quite easily record its hottest ever summer.
