March 2026 was exceptionally sunny over most of the Alaska, Yukon Territory and NWT in ERA5 reanalysis courtesy @[email protected]. For much of central Alaska there was more sunshine than in any March since 1979. Graphic courtesy @[email protected]. #akwx #ytwx #ntwx #Climate

Wildfire area burned in the Northwest Territories, Canada has nearly doubled in the past two weeks, with more than 1.33 million hectares (3.30 million acres) burned in 2025. Although wildfire as been minimal in the Yukon Territory and Alaska this month, the northern North American total area burned is now nearly twice the 1988 to 2024 median and on par with 2022 and 2024. @Climatologist49

The 2025 wildfire season is about done in Alaska and the Yukon Territory, but is still going in the NWT. Seasonal review for northern North America wildfire now posted in the latest from the Alaska and Arctic Climate newsletter. #akwx #ytwx #ntwx #Canada alaskaclimate.substack.com/p/summer-202...

Northern North America wildfire area burned updated to Sunday. Area burned is higher than last year at this point in the season. Alaska has burned about 42 percent more area, Yukon Territory about 17 percent more and the Northwest Territories about 4 percent more.

Wildfire area burned in northern North America is ahead of this time last sumner. Percentage-wise the biggest increase is in the Yukon Territory. However, in 2024 the last days of June saw rapid growth in wildfires in Alaska and the YT, so this will look different once June 2025 is complete. #akwx #ytwx #ntwx #Wildfire #Arctic

Alaska and vicinity comparison of April 15 snowpack snow water equivalent against same date last year. Much lower SWE southwest Alaska and lower Mackenzie valley. Much higher in the central Interior. Data from ERA5. #snow #Spring2025 #akwx #ytwx #ntwx @Climatologist49

The 2024 wildfire season is nearly finished in Northern North America (a few fires continue in southern portions of the Yukon and Northwest Territories). I've got a seasonal wrap-up posted on the Alaska and Arctic Climate newsletter. @Climatologist49

Northern North America summer 2024 wildfire area burned. Alaska early season loaded, Northwest Territories late summer loaded, Yukon Territory roughly even across the three months. #akwx #ytwx #ntwx #Wildfire #Canada #Summer2024

In case you're wondering, 2024 northern North America wildfire area burned through August 23rd. Northwest Territories, Canada fires accounts nearly 80 percent of the area burned, which is not quite as lopsided as 2023, when NWT fires accounted for more than 90 percent of northern North America wildfire area burned. The season is effectively over in Alaska and most of the Yukon but still going in the NWT.

Some new information and extreme temperatures reports in my updated post on Northwest North American heatwave of August 5-9, 2024. Deadhorse, Alaska 89, Inuvik, NWT at 95F and apparently, Canada's highest temperature north of the Arctic Circle. Hard to believe, but it's our world now.

The northwest North America August 2024 heatwave is shifting east. Here are the highest reported temperatures this past week. Two locations with more than 50 years of observations set all-time record highs: Deadhorse Airport at Prudhoe Bay, Alaska and Inuvik, Northwest Territories. Fort Good Hope appears to have reported the highest reliable temperatures: 37.0C (99F) on Friday. #akwx #ytwx #ntwx #Climate #ClimateChange #Summer2024

Horrifyingly incredible: in the Sahtu region of the Northwest Territories, Canada, high temperature at both Ft. Good Hope (66.2ºN) and Norman Wells (65.3N) through 635pm MDT 36.7C (98F)! These temperatures are very close to the highest in the July 2023 record heatwave. Little Chicago (67.2ºN) up to 36.3C (97F). #Arctic #Heatwave #Canada #ntwx

Impressive early August 2024 heatwave over northwest North America. During the past three days, all-time records apparently set at Deadhorse, Alaska (31.7C, 89F) and Inuvik, NWT (34.5C, 94F. Northway 87F on August 6 is the highest temperature so late in the year. The August 7 temperatures not final so some of the NWT sites could finish up slightly higher. #akwx #ytwx #ntwx #Climate #Canada #Alaska #ClimateDiary #Summer2024

June 28 update on northern North American wildfire. Reversed from 2023, when the Northwest Territories was very high, Yukon Territory in the middle and Alaska very low (at this point in the season). Graohic courtesy NASA/FIRMS. #akwx #ytwx #ntwx #Alaska #Canada #Wildfire #Summer2024

Snowpack snow water equivalent as a percent of the 1991-2020 median in and around Alaska as of April 8th. Most of mainland Alaska and northern Yukon Territory had near to above normal snowpack but Alaska Panhandle, British Columbia, western Northwest Territories and northern Alberta well below usual snowpack for this point in the Spring.

April 1 snowpack snow water equivalent as a percent of 1991-2020 median in/around Alaska from ERA5 Land courtesy of ECMWF/Copernicus. Most of Alaska snowpack is near to above normal with a small exception in the central Interior and a larger exception in central and southern Southeast. In Canada, much of northern BC, NW Alberta and western NWT snowpack is far below typical for this point in the season. #akwx #ytwx #ntwx #Arctic #SnowPack #Hydrology #Wildfire

Snowpack (snow water equivalent) as March 1, 2024 from ERA5 for Alaska and vicinity. Most of Alaska except for southern Southeast are near to above median. Different story in parts of northwest Canada, where snowpack is half or less of in western Northwest Territories and northeast BC. #akwx #ytwx #ntwx #SnowPack #Climate

Arctic-wide 2023 temperature departures from the 1991-2020 average from ERA5 courtesy of ECMWF/Copernicus. The Canadian and portions of the eastern Russian Arctic were exceptionally mild. For the Arctic as a whole (land and ocean poleward of 60N), this was the fifth warmest year on record, with more than 85% of the #Arctic warmer than the 30-year average. For Canada's Northwest Territories 2023 was by far the warmest year. #Canada #ntwx #ClimateChange

July through September 2023 average temperature was record high (since 1950) across much of northwest Canada, northeast Alaska and parts of the Alaska North Slope. For the both the Yukon Territory and Northwest Territories, #Canada this was the warmest late summer season on record.

Terrible air quality in #wildfire smoke Saturday morning around Great Slave Lake, NWT. There are more than half a dozen sensors in the Yellowknife area and all are reporting PM2.5 AQI above 450. More than 4 million hectares have burned in the NWT this season. Graphic and data courtesy PurpleAir. #ntwx #CanadaWildfire #Canada

How cloudy was it this summer around Alaska? From our friends at the World Climate Service using ERA5 reanalysis, #Summer2023 sunshine compared to the previous 60 years. Southeast Alaska and NW Canada well above average sunshine 🌞. For a large portion of Kodiak Island, the Kenai Peninsula and the eastern Bering Sea region, this was either the lowest or second lowest sunshine summer since 1963. ☁︎ #akwx #ytwx #ntwx

Northwest North America (Alaska, Yukon Territory, Northwest Territories) #wildfire this summer, in the latest estimates, has burned more than 3.4 million hectares (8.5 million acres), the highest since 2014, but well below the terrible summer of 2004. This year NWT fires accounts for 90 percent of the total area burned. #akwx #ytwx #ntwx #Summer2023

Latest #wildfire estimate from Northwest Territories Department of Environment and Climate Change shows 3.43 million hectares burned thus far in 2023. This is now the greatest area burned in NWT in the past 44 years, eclipsing the previous highest of 3.42 million ha in 2014. 2023 area is sure to increase. #ntwx #Arctic #Canada #CanadaWildfire #Summer2023

Government of Northwest Territories, #Canada updated estimate of #wildfire area burned is now at 3.36 million ha (7.76 million acres). Since 1988, the most area burned in season in the NWT was 3.42 million ha in 2014. #ntwx #Summer2023 #CanadaWildfire

It's the second half of August, it's starting to get dark at night again and that can only mean that summer is on the run in the North. The first of what's sure to be several summer summaries now posted in the Alaska and Arctic Climate Newsletter, this one on 2023 high temperatures and wildfire. #akwx #ytwx #ntwx #Summer2023 #Climate
