Climate

nterior portions of Connecticut have a humid continental climate, while other parts, especially the Connecticut shoreline (southern four counties), have a humid subtropical climate with seasonal extremes tempered by proximity to the Atlantic Ocean. The city of Bridgeport (on Long Island Sound), like most other areas in metropolitan New York, has a humid subtropical climate under the Koppen Climate Classification system. Hartford (35 miles inland) has a humid continental climate. The coast of Southern Connecticut is often considered to be the farthest north on the U.S. east coast that subtropical "indicator" species such as the Dwarf Palmetto, Needle Palm, Windmill Palm, Crape Myrtle and the Southern Magnolia can be successfully cultivated.

Winters are generally considered to be cold, with average temperatures ranging from 31 °F (−1 °C) in the maritime influenced southeast to 23 °F (−5 °C) in the northwest in January. The average yearly snowfall is about 25–100" (64–254 cm) across the state, with higher totals in the northwest. Spring has variable temperatures with frequent rainfall. Summer is hot and humid throughout the state, with average highs in New London of 81 °F (27 °C) and 87 °F (31 °C) in Windsor Locks. Fall months are mild and bring colorful foliage across the state in October and November. During hurricane season, tropical cyclones occasionally affect the region. Thunderstorms are most frequent during the summer, occurring on average 30 times annually. These storms can be severe, and the state usually averages one tornado per year.
