Planet Earth was not only record warm July through September 2023 but was also unusually dry. Globally, this was the lowest July-September precipitation since 2000. #Australia and #Malaysia, #Brazil, eastern #Europe and parts of Africa standout as unusually dry. Southwest US and eastern Mediterranean well above average precipitation. Data from ERA5 courtesy of ECMWF/Copernicus. #Climate #ClimateMonitoring @ZLabe @Climatologist49
*Inadvertently attached wrong graphic. Now with correct graphic.
August average temperatures were warmer than normal almost everywhere in and around Alaska, with the eastern Interior and adjacent areas in the Yukon especially warm. Eagle had the warmest August on record, Tok second warmest, Fairbanks and Gulkana third warmest. Southeast was again mild, with Sitka airport having second warmest August. #akwx #ytwx #Summer2023 #ClimateMonitoring

August rainfall relative to normal around Alaska showed considerable variability, but except for portions of the eastern Interior was mostly above normal, and in portions of Southcentral and western Alaska rainfall was way above normal. This same basic pattern prevailed in June and July too. #akwx #Summer2023. #ClimateMonitoring
Third installment of the July 2023 Alaska and Arctic #climate summary is now posted. For the #Arctic as a whole, this was the second warmest July on record. #akwx #ytwx #Summer2023 #ClimateMonitoring

Dramatic contrast in July precipitation in and around Alaska in ERA5 courtesy of ECMWF/Copernicus using a normals 1991-2020 baseline. Parts of western and Southcentral #Alaska much wetter than usual, with some areas with twice the normal rainfall. Eastern mainland Alaska, Southeast and most of the Yukon Territory and Northwest Territories were considerably drier than average. #akwx #ytwx #ntwx #ClimateMonitoring #Summer2023

Pan-Arctic July 2023 temperature departures from the 1991-2020 average from ERA5 courtesy of ECMWF/Copernicus. Most of the Greenland Ice Sheet, northwest Canada and northern Alaska were exceptionally warm. Cooler than average July northeast Canada and most of the Scandinavian #Arctic. July temperature departures are always small over the central Arctic Ocean because heat goes into melting snow and sea ice.

There is so much going on with #Alaska and #Arctic #climate that it's going to take a while to sift through it all. In the meantime, new post up with some of the Alaska highlights from July. #akwx #ClimateMonitoring #Summer2023
https://alaskaclimate.substack.com/p/july-2023-alaska-climate-highlights
July 2023 average temperatures in #Alaska:
Warmest any month:
Utqiaġvik 48.4F (9.1C)
Eagle (coop) 65.5F (18.6C)
Northway 65.5F (18.6C)
Tok 64.7F (18.2C)
Ft. Greely/Delta Junction 65.3F (18.5C)
Second warmest month:
Fairbanks 67.1F (19.5C), July 1975 warmer
Deadhorse 53.8 (12.1C), July 1989 warmer
Third warmest month
Juneau 60.4F (15.8C), July 2018 & 2019 warmer
Other place surely in top three but lack long term climate obs.
July 2023 temperature departures from the 1991-2020 average (ºF) across Alaska and NW Canada. Mid-summer departures of 6 to 11ºF above normal (north Slope eastward into northern Yukon and northwest NWT) are astounding. Anchorage area & Kenai Peninsula westward to southwest mainland #Alaska only bastion of below normal for the month. #akwx #ClimateMonitoring #Summer2023

A few of the many #climate highlights for July 2023 around Alaska. Dramatic contrast between Southcentral/Southwest #Alaska and the North Slope, eastern Interior and Southeast. In addition to record dry at Yakutat, Gulkana, Juneau and Sitka all had a top ten driest July. Eagle as well as Northway and Utqiaġvik had their warmest month on record. #akwx #ClimateMonitoring #ClimateDiary #Summer2023 @Climatologist49 @AK_OK @YJRosen
July 2023 total rainfall as a percent of average. Dramatic contrast between Southcentral and Southwest Alaska and the eastern Interior and Southeast. Parts of the southeast Interior were also quite dry in June, with Delta Junction/Ft. Greely coming in the driest June-July on record, with the two month precipitation just 31 percent of normal. In Southeast, Juneau Airport 4th driest July past 80 years. #akwx #ClimateMonitoring
@Climatologist49 @AK_OK
Utqiaġvik, #Alaska July 2023 average temperature of 48.4F (9.11C) edges out July 2019 (48.3F, 9.06C) as the warmest month on record. The low temperature for the month of 33F (+0.6) marked only the third July to remain above freezing the entire month. Decreasing nearshore #SeaIce is part of the driver of the increase in recent years. Unbroken climate observations at Utqiaġvik since late 1920. #akwx #Climate #ClimateChanrge #ClimateMonitoring
@Climatologist49 @cinderbdt AK_OK@journa.host @YJRosen
And it begins: July was the warmest month on record at Eagle, #Alaska The NWS cooperative observations put the average temperature at 65.5F (18.6C). This exceeds the previous warmest month of June 2004, when the average temperature was 65.2F (18.4C). The previous warmest July was 2007, with an average temperature of 64.1F (17.8C).
There are about 100 years (not consecutive) of reliable climate observations at Eagle.

@Climatologist49 @extretemps
Fairbanks is on track for this month to finish up as the second warmest July in the past 118 years. Only July 1975 warmer. Other locations in #Alaska also track for a near record warm month #akwx #Summer2023 #ClimateMonitoring
@Climatologist49
Alaska temperature and precipitation departures from normal for the first half of July. Very wet north and west, very dry Southeast. This kind of west-to-east contrast across #Alaska is common in the cold season but unusual in mid-summer when, small scale features tend to dominate, though there's a hint of that in the temperatures.
#akwx #ClimateMonitoring #Summer2023 #Climate
Temperatures for early summer 2023 for Alaska overall are running slightly below than the 1991-2020 average, as seen in the ACCAP Alaska statewide temperature index. @Climatologist49 and I developed the index in order to answer questions like "has it been hot/cold in Alaska lately?" Alaska's a big place with widely varying climates, and the index tries to account for that. You can play along at home at:
I've got a short post up summarizing the extreme heat in northwest Canada and far eastern Alaska July 7 and 8. #akwx #ytwx #ntwx #ClimateCrisis #ClimateMonitoring #ClimateDiary #ExtremeWeather

@Climatologist49 @evaholland @andrewfreedman @yjrosen @AK_OK
Sea surface temperature departures from 1991-2020 average for the first week of July from the NOAA/PSL/ESRL high resolution data. Much below normal #sst in the western Chukchi Sea reflecting late persisting #SeaIce. Southern Gulf of Alaska remains cooler than average west and above normal east. Big west to east difference Bering Strait compared to Norton and Kotzebue Sounds. #akwx #Arctic #ClimateMonitoring #Oceanography
