full_context: Document 1: Atlantic City, New Jersey: Summers are typically warm and humid with a July daily average of 75.6 °F (24.2 °C). During this time, the city gets a sea breeze off the ocean that often makes daytime temperatures much cooler than inland areas, making Atlantic City a prime place for beating the summer heat from June through September. Average highs even just a few miles west of Atlantic City exceed 85 °F (29 °C) in July. Near the coast, temperatures reach or exceed 90 °F (32 °C) on an average of only 6.8 days a year, but this reaches 21 days at nearby Atlantic City Int'l.[a] Winters are cool, with January averaging 35.5 °F (2 °C). Spring and autumn are erratic, although they are usually mild with low humidity. The average window for freezing temperatures is November 20 to March 25, allowing a growing season of 239 days. Extreme temperatures range from −9 °F (−23 °C) on February 9, 1934 to 104 °F (40 °C) on August 7, 1918.[b]

Document 7: North Carolina: The climate of the coastal plain is influenced by the Atlantic Ocean, which keeps conditions mild in winter and moderate, although humid, in summer. The highest coastal, daytime temperature averages less than 89 °F (32 °C) during summer months. The coast has mild temperatures in winter, with daytime highs rarely below 40 °F (4 °C). The average daytime temperature in the coastal plain is usually in the mid-50s °F (11–14 °C) in winter. Temperatures in the coastal plain only occasionally drop below the freezing point at night. The coastal plain averages only around 1 inch (2.5 cm) of snow or ice annually, and in many years, there may be no snow or ice at all.
Document 8: Boston: Fog is fairly common, particularly in spring and early summer, and the occasional tropical storm or hurricane can threaten the region, especially in late summer and early autumn. Due to its situation along the North Atlantic, the city often receives sea breezes, especially in the late spring, when water temperatures are still quite cold and temperatures at the coast can be more than 20 °F (11 °C) colder than a few miles inland, sometimes dropping by that amount near midday. Thunderstorms occur from May to September, that are occasionally severe with large hail, damaging winds and heavy downpours. Although downtown Boston has never been struck by a violent tornado, the city itself has experienced many tornado warnings. Damaging storms are more common to areas north, west, and northwest of the city. Boston has a relatively sunny climate for a coastal city at its latitude, averaging over 2,600 hours of sunshine per annum.

Document 10: New York City: Winters are cold and damp, and prevailing wind patterns that blow offshore minimize the moderating effects of the Atlantic Ocean; yet the Atlantic and the partial shielding from colder air by the Appalachians keep the city warmer in the winter than inland North American cities at similar or lesser latitudes such as Pittsburgh, Cincinnati, and Indianapolis. The daily mean temperature in January, the area's coldest month, is 32.6 °F (0.3 °C); however, temperatures usually drop to 10 °F (−12 °C) several times per winter, and reach 50 °F (10 °C) several days each winter month. Spring and autumn are unpredictable and can range from chilly to warm, although they are usually mild with low humidity. Summers are typically warm to hot and humid, with a daily mean temperature of 76.5 °F (24.7 °C) in July and an average humidity level of 72%. Nighttime conditions are often exacerbated by the urban heat island phenomenon, while daytime temperatures exceed 90 °F (32 °C) on average of 17 days each summer and in some years exceed 100 °F (38 °C). In the warmer months, the dew point, a measure of atmospheric moisture, ranges from 57.3 °F (14.1 °C) in June to 62.0 °F (16.7 °C) in August. Extreme temperatures have ranged from −15 °F (−26 °C), recorded on February 9, 1934, up to 106 °F (41 °C) on July 9, 1936.
