As in other Rio Grande Valley cities, "Winter Texans" are a large part of Harlingen's transient population and a significant contributor to its economy. Winter Texans are generally retirees from the northern Midwestern states and Canada who come to escape the northern winter weather between November and March. Because of the mild winters, the Harlingen area plays host to thousands of Winter Texans who have made Harlingen their “home away from home” or own a second home here.
