Unlike much of the Lower 48, Anchorage and surrounding areas are enjoying fairly normal rainfall after a record-setting winter this year. While temperatures soar in down south, things have remained fairly average since the all-time record 7 1/2 feet of snowfall began melting away in March and April.
Anchorage is blessed with a mild growing climate due in part to its northern latitude and it's proximity to the Cook's Inlet which is moderated heavily by the Japanese Current flowing through equatorial regions before turning North along the coast of the U.S. and then swirling up past Canada's British Columbia coast, Southeast Alaska to finally expend the last vestiges of energy milling about the Alaskan Gulf just south of Anchorage and the rest of South-central Alaska. Anchorage proper is protected by the Chugach Mountains and the Alaska Range which help avert severe storms.
So while much of the U.S. is baking in the heat of the hottest summer and lowest rainfall on record for many areas, Alaska is enjoying very typical rainfall and temperatures. A couple of days in June saw the one exception to that trend with highs reaching the mid-80s for the better part of a week (which is nearly unheard of), but a bought of rainy weather calmed things down and brought everyone back to reality.
