By Joe Viechnicki, KFSK — Southeast Alaska’s three-day heat wave appears to have run its course, but not before setting new all-time records for the month.
The National Weather Service reports new all-time high temperatures for the month of March in Sitka and Petersburg, where the thermometer hit 62 degrees on Monday, March 18.
Kimberly Vaughan is a forecaster with the National Weather Service in Juneau.
“We’ve hit just numerous record high temperatures for the day but also we’re breaking a lot of the monthly March records,” said Vaughan. “So it’s the warmest March temperature we’ve ever seen.”
In Petersburg, the previous high for March was 61 degrees set in 1994. Sitka’s previous high was 61 degrees in March of 1998. Sitka topped that record on Tuesday, hitting 67 degrees.
Unreasonably hot: Here's a sampling (not complete) of March and seasonal all-time record high temps that have been set in the past few days in Alaska and northwest Canada.

All-time high March temperatures were also set Tuesday in Ketchikan, hitting 65 degrees, Yakutat at 60 degrees, Juneau airport at 59 degrees and Haines at 56 degrees. And Klawock hit 70 degrees Tuesday, the first to hit the 70 degree mark this year.
“That broke the previous daily record that was 55 degrees set back in 2015,” Vaughan said. “That did not break the monthly record which is actually 71 degrees which was set back on March 31st in 2016. The exciting thing about that is Klawock was the warmest spot in Alaska yesterday.”
Wednesday began with the prospect of more records – until cloud cover rolled in, along with cooler air in the 50s, more typical of spring conditions which – incidentally – officially began with the Vernal Equinox at 5:58 p.m.
