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

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

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.

@Climatologist49

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:

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
@Climatologist49

90F (32.2C) at Eagle Airport at 2pm AKDT Friday. I believe this is the first "official" 90F in Alaska since early August 2021 (last summer's highest 89F). #akwx #ClimateMonitoring

@Climatologist49

How gray has it been this early summer in Alaska? From our colleagues at the World Climate Service, here's the ERA5 ranks of May-June sunshine relative to the 1993-2022 period. A huge swath of South Central & Southwest #Alaska had less sun this year than any May-June in the past 30 years. #akwx #ClimateMonitoring

Lots of good data in the article though I find it a bit all over the place. All our major dams are below normal levels. #Pagasa declared the onset of #ElNiño last July 4.

"Ana Liza Solis, of Pagasa’s #ClimateMonitoring and prediction unit, earlier said that El Niño will likely become powerful in the following months and will persist until the first quarter of 2024." #Philippines #HeatWave
