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.

The Santa Anas are katabatic winds (Greek for "flowing downhill") arising in higher altitudes and blowing down towards sea level. [7] The National Weather Service defines Santa Ana winds as "a weather condition [in southern California] in which strong, hot, dust-bearing winds descend to the Pacific Coast around Los Angeles from inland desert regions".

As temperatures drop after sunset, the marine layer deepens and coastal stratus clouds thicken. While the vortex is relatively small, rarely more than 100 miles (160 km) in diameter, it can extend into inland valleys and even into the southwestern Mojave Desert. A very strong Catalina eddy can be as deep as 6000 feet (1.8 km).
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).
