Abstract

"Chicago (Cook County) has a temperate continental climate, dominated by maritime tropical air from the Gulf of Mexico from about March through November. Gulf air generally supports relative humidities of about 60% during the day and 85% at night. This is the airmass which yields a ""muggy"" environment, particularly during June through August. During these months, there are occasional, brief interruptions of drier, cooler air from the Pacific Ocean, but they typically only last a few days. Within a few miles of the Lake Michigan shore, the climate is modified by lake breezes, yielding temperatures 2 to 5°F warmer on winter days than those measured at O'Hare (if lake is not frozen), and cooler by a like amount on summer days."
