Well, it's 3:05 am on June 1st where I live (Central Daylight Time), so summer's here in most of the world. In Alaska, it's a few minutes old.
But there are still some places in the Canadian High Arctic that have yet to see there first above freezing temperature this year. Here's a rundown. A few places have had their first above freezing temperatures of the year just in time for summer:
Resolute - May 9
Grise Fiord - May 30
Pond Inlet - May 31
Arctic Bay - May 30
Alert - Not yet. Highest temperature -2.9 C / 26.8 F on May 19.
Eureka - Not yet. Highest temperature -1.9 C / 28.6 F on May 20.
Cambridge Bay - Not yet. Highest temperature -0.7 C / 30.7 F on May 29.
Cambridge Bay, with nearly 1,800 people and at only 69 degrees north, looks to be among the very few (if not the only) permanently inhabited town in North America that has entered summer without getting above freezing.
It's odd to think that places with July highs of 5-7 C / 41-45 F managed to get above freezing while it was still spring, whereas Cambridge Bay, nearly warm enough to be a Dfc climate with its 13 C / 55 F July high, hasn't managed it yet.
I wonder if an actual Dfc climate with trees has ever gone into June without getting above freezing, because the latest I've typically seen average highs cross freezing in Dfc climates is around May 20, these are obviously borderline with tundra climates that can barely manage tree growth. Cam Bay's crosses freezing May 30.
Resolute has only managed one brief foray above freezing on May 9, so short that no hourly observations measured above freezing, but Environment Canada says it squeaked it out with 0.6 C / 33.1 F, and it looks plausible. The 5.8 C / 42.4 F on May 19 is an obvious error, though.
