What December is like in San Diego
December is mild and festive. Highs sit near 65F (18C), nights get chilly, and the first winter rain can arrive. The ocean is cold. Early in the month is quiet and fairly cheap, but prices and crowds rise over the holidays as families come for sun. Gray whales start passing Point Loma, and Balboa Park lights up for December Nights.
This month suits families escaping winter, holiday lovers, and anyone who wants whales and lights instead of beach swimming. It is not a swim month. If you want the beach at its best, come back in September. If you want quiet and low prices, choose the first half of December or January.
