Drizzlin’ in December

San Diegans know we have it good when it comes to winter: The average high temperature in December is 63.3°. It’s typically the month with the most rainfall — 5.8 days, or up to 1.65 inches of total rain — and the shortest days with 10 hours of daylight.

Keeping it cool in January

SD usually kicks off the new year with slightly cooler temperatures and rain: An average high of 63.1° and 1.06 inches of accumulated precipitation in January. This month is known to bring higher humidity — approx. 60%. Combined with cooler temps on land and sea, this could make the weather feel colder than it is. January-March have the lowest UV Index, but sunscreen is always a good idea.

Chillin’ in February

February usually brings the coldest temps: An average high of 63.1° and low of 51.8°. Average ocean temperatures dip to 58.7° — the coldest month of the year for SD’s seawater. Relative humidity increases to 64%, so scattered showers could become more frequent. At just over 11 hours, the days are getting slightly longer.
