San Diego 10 day weather forecast, weather report & climate zone
The San Diego weather story
The U.S. Weather Bureau describes the San Diego climate zone as the most nearly perfect in America. It can be characterized as Mediterranean-like, with mild winters and moderate 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 news, 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 map and San Diego weather satellite image are useful tools to predict the San Diego weather forecast.

San Diego's climate is really four microclimate zones
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.

The official San Diego weather forecast, weather averages and climate statistics are for the San Diego International Airport, which is located on the coast. However, as you travel east 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 report for San Diego and protect us from extreme weather reports. That's why the San Diego climate zone 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 weather storms miss San Diego!
Most of our occasional winter storms come in from the north. And since the jet stream usually tracks north of San Diego, we rarely have the violent winter storms with heavy rainfall forecasts 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 23 inches. You can make your own weather forecast by looking at the San Diego weather radar map and San Diego weather satellite image.
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. |
