Why is it so windy in Southern California?
Any low-pressure area over the Pacific Ocean, off the coast of California, can change the stability of the Great Basin High, causing a pressure gradient that turns the synoptic scale winds southward down the eastern side of the Sierra Nevada and into the southern California region.
What are the prevailing winds in Southern California?
Winds. California lies within the zone of prevailing westerlies and on the east side of the semi-permanent high pressure area of the northeast Pacific Ocean. The basic flow in the free air above the state, therefore, is from the west or northwest during most of the year.
What is the windiest month in Southern California?
The windier part of the year lasts for 5.8 months, from November 7 to April 30, with average wind speeds of more than 6.9 miles per hour. The windiest day of the year is December 31, with an average hourly wind speed of 8.7 miles per hour. The calmer time of year lasts for 6.2 months, from April 30 to November 7.
Has Southern California ever had a tornado?
On March 1, 1983, a twister tore its way north through South Los Angeles, causing 30 injuries and 9 deaths and at least $5 million in damage. It set the record for the most destructive tornado to have occured in Los Angeles County.
Why is the wind so strong in California?
The Diablo wind is created by the combination of strong inland high pressure at the surface, strongly sinking air aloft, and lower pressure off the California coast. While hydraulic jumps can occur with Santa Ana winds, the same thermodynamic structure that occurs with them typically favors “gap” flow more frequently.
What’s the windiest city in California?

What are the regions from which wind blows into Southern California?
Santa Ana Winds occur when air from a region of high pressure over the dry, desert region of the southwestern U.S. flows westward towards low pressure located off the California coast. This creates dry winds that flow east to west through the mountain passages in Southern California.
Can California have tornadoes?
Tornadoes in California are not unheard of. The state averages a dozen or so tornadoes per year, most of them quick-hitting and weak. Most form in the Central Valley, where low-level southerly winds are accelerated up the length of the valley. Storms in California do occasionally rival those of Tornado Alley.
