SAN DIEGO WEATHER, CLIMATE & WEATHER FORECAST

San Diego weather and climate information and weather forecast

The San Diego weather story

The U.S. Weather Bureau describes the San Diego climate as the most nearly perfect in America. It can be characterized as Mediterranean-like, with warm winters and cool summers. The typical San Diego weather forecast of "sunny and mild" is just one of the many reasons why we enjoy living here and why so many people love to visit.

When tourists hear the beautiful San Diego weather forecast, they flock here from the midwest and east coast to escape the frigid winter cold and from the desert and southeast to get away from the blistering summer heat. The San Diego weather radar and satellite is a useful tool to predict the San Diego weather forecast.

San Diego's climate is really several microclimates

San Diego County is huge, covering an area of 4,225 square miles. It stretches 65 miles from north to south and 86 miles from east to west. This size and the varied terrain creates a wide variety in the San Diego local weather conditions that are known as the San Diego microclimates. The official San Diego weather forecast and weather statistics are for the San Diego International Airport, which is located on the coast. However, as you travel into the canyons, mountains and deserts, San Diego's climate changes dramatically.

What makes the San Diego climate so perfect?

The prevailing breezes off the Pacific Ocean temper the weather in San Diego and protect us from extreme weather conditions. That's why the San Diego climate is so moderate, compared with other places along the same latitude. The winds here are typically light, out of the northwest, except during "Santa Ana" conditions.

That's when the San Diego weather forecast includes high winds blowing from the east, bringing in dry, hot desert air that can push the temperature up into the 90ºs for a few days at a time. "Santa Ana's" can fly in anytime, but they usually occur in September and October and are strongest in the inland valley and mountain San Diego microclimates.

Most big storms miss San Diego!

Most of our occasional winter storms come in from the south. And since the jet stream usually tracks north of San Diego, we rarely have the violent winter storms with heavy rainfall that flood Los Angeles and Orange county - just 100 miles to the north. For example: the severe winter storms of 2004-05 dropped a record-setting 35 inches of rain in Los Angeles, while San Diego received only about 23 inches. You can make your weather forecast by looking at San Diego weather radar and satellite.

Also, San Diego is uniquely located to avoid the summer monsoons that blow south of us across Mexico and Arizona. The San Diego weather forecast does occasionally include summer thunderstorms in the mountains. Several times each winter, a snow storm will blanket the Laguna Mountains, creating spectacular views and drawing delighted San Diego residents to play in the snow.
