Summers in Alabama are among the hottest in the United States, with high temperatures averaging over 90 °F (32 °C) throughout the summer in many parts of the state. In the extreme south, summer's heat is tempered slightly by winds from the Gulf of Mexico which often blow inland by up to 10–15 miles.
In the United States, the mean ( max + min / 2 ) daily temperature in Fahrenheit and a temperature of 65 °F (18 °C) is used. [3] If the mean daily temperature is 65 °F, no degree days are counted. If the mean daily temperature is below 65 °F, the mean degrees Fahrenheit below 65 °F are counted as the heating degree day.
This is a list of cities by average temperature (monthly and yearly). The temperatures listed are averages of the daily highs and lows. Thus, the actual daytime temperature in a given month may be considerably higher than the temperature listed here, depending on how large the difference between daily highs and lows is.
Winds aloft, officially known as the winds and temperatures aloft forecast, (known as "FD" in the US and Canada, but becoming known as "FB", following the World Meteorological Organization [WMO] nomenclature), is a forecast of specific atmospheric conditions in terms of wind and temperature at certain altitudes, typically measured in feet (ft) above mean sea level (MSL).
A humid subtropical climate is a subtropical-temperate climate type, characterized by long and hot summers, and cool to mild winters. These climates normally lie on the southeast side of all continents (except Antarctica), generally between latitudes 25° and 40° and are located poleward from adjacent tropical climates, and equatorward from either humid continental (in North America and Asia ...
The wet-bulb globe temperature (WBGT) is a measure of environmental heat as it affects humans. Unlike a simple temperature measurement, WBGT accounts for all four major environmental heat factors: air temperature, humidity, radiant heat (from sunlight or sources such as furnaces), and air movement (wind or ventilation).

This explains why an area like the Pinnacles National Park can have high temperatures of 38 °C (100 °F) during a summer day, and then have lows of 5–10 °C (41–50 °F). At the same time, Washington D.C. , which is much more humid, has temperature variations of only 8 °C (14 °F); [ 1 ] [ dead link ] urban Hong Kong has a diurnal ...
The Fahrenheit scale (/ ˈ f æ r ə n h aɪ t, ˈ f ɑː r-/) is a temperature scale based on one proposed in 1724 by the European physicist Daniel Gabriel Fahrenheit (1686–1736). [1] It uses the degree Fahrenheit (symbol: °F) as the unit.
