A person might think that since we get our maximum sunlight on the summer solstice (on or about June 21), we should also get our peak warmth then. The sun’s calling the shots, right?
Not entirely, said former Alaskan Martha Shulski, author of “The Climate of Alaska” and now climatologist for the state of Nebraska.
“Alaska is warmest a few weeks after the solstice,” she said.
A lag exists between the peak of solar energy input and the warmth we feel. It’s a phenomenon that also shows up in winter or when people’s pipes mysteriously freeze in May.
