Monthly weather forecast and Climate
Los Angeles, CA

Los Angeles experiences a Mediterranean type of climate (Köppen climate classification Csb on the coast, Csa inland) with hot and dry summers and wet and mild winters. It is the second most populous city in the United States and lies in the proximity of the Pacific Ocean with many mountain ranges surrounding the city. The ocean is a source of cool breezes during summer and keeps the temperatures warmer in winter. Mountain ranges protect Los Angeles from the cold winds that blow from the north, as well as retain the warm winds that blow from Mexico.

Los Angeles has different microclimates, as the city is vast and covers coastal areas, flat terrain as well as hilly areas and mountains. Summers are hot and sunny with the average highs in the eighties. June gloom frequently occurs on summer mornings, which is a cloudy, foggy and damp weather pattern due to the difference in the sea and land temperatures. Winters are mild with average lows in the mid-forties, but the occasional hot and dry Santa Ana wind raises the temperatures.

Snow is common in the surrounding San Gabriel Mountains in the winter as also the majority of the scarce rainfall of 15" (381mm).

The best time for a visit is during spring from March to May when the crowds are less oppressive, and the average temperatures are in the low 50°F (10°C) to low 80°F (26.7°C). The spring air quality is the best of all the seasons which makes exploring and walking around the various attractions enjoyable.
