"This place has only two seasons—winter and August” (or “winter and the Fourth of July") is said of any place that has a very long winter season. “We have but two seasons—winter and the Fourth of July” was said about St. Paul, Minnesota, in 1893. “Eldora had two seasons, winter and August” was said about Eldora, Colorado, in 1899.
Similar sayings include “There are only two seasons in the North—winter and road construction” and “Minnesota has two seasons—winter is coming and winter is here.”
