Climate Overview
Portland
Portland is Maine's largest city on Casco Bay, with a maritime New England climate. The Atlantic provides moderation but Portland still experiences full nor'easter potential with heavy snow and powerful ocean storms. The Old Port's waterfront cobblestones and Victorian commercial blocks create a beautiful but exposed coastal setting. Summers are famously pleasant and increasingly popular.
Chicago
Humid continental — cold harsh winters, hot humid summers, severe storms
Chicago lives up to its Windy City nickname. Lake Michigan creates its own microclimate — cooler summers and heavier lake-effect snow in winter. Summers are warm but brief; winters are among the harshest of any major American city.
