Boston Climate - Weather - Temperature
"Boston has a humid continental climate (Köppen climate classification Dfa), a phenomenon common to coastal southern New England. Summers are typically warm and humid, while winters are cold, windy, and snowy. Prevailing wind patterns that blow offshore affect Boston, minimizing the influence of the Atlantic Ocean.
Spring in Boston can be warm, with temperatures as high as the 90s when winds are offshore, although it is just as possible for a day in late May to remain in the lower 40s because of cool ocean waters. The hottest month is July, with an average high of 82 °F (28 °C) and an average low of 66 °F (18 °C), with conditions usually humid. The coldest month is January, with an average high of 36 °F (2 °C) and an average low of 22 °F (−6 °C).Periods exceeding 90 °F (32 °C) in summer and below 10 °F (−12 °C) in winter are not uncommon but are rarely prolonged. The record high temperature is 104 °F (40 °C), recorded on July 4, 1911. The record low temperature is −18 °F (−28 °C), recorded on February 9, 1934. February in Boston has seen 70 °F (21 °C) only once in recorded history, on February 24, 1985. The highest temperature recorded in March was 89 °F (31 °C), on March 31, 1998.
Boston's coastal location on the North Atlantic, although it moderates temperatures, also makes the city very prone to Nor'easter weather systems that can produce much snow and rain. The city averages about 43 in (108 cm) of precipitation a year, with 40.9 in (104 cm) of snowfall a year.Snowfall increases dramatically as one goes inland away from the city (Especially north and west of the city)—away from the warming influence of the ocean. Most snowfall occurs from December through March. There is usually little or no snow in April and November, and snow is rare in May and October. Fog is prevalent, particularly in spring and early summer, and the occasional tropical storm or hurricane can threaten the region, especially in early autumn. Due to its situation along the North Atlantic, the city is often subjected to sea breeze, especially in the late spring, when water temperatures are still quite cold and temperatures at the coast can be ten to twenty degrees colder than a few miles inland, sometimes dropping by that amount near midday."
