Huntington Beach California weather is largely influenced by Pacific Ocean currents, providing what's described as Mediterranean climate. Winters are beautiful and mellow, seldom dipping below 65 degrees during the day. Summers are mellow, as well, and you'll rarely see the thermometer reach 90 degrees.
When you travel to HB, be sure to dress in layers and bring a jacket. Nights can be cool and chilly, but days warm to pleasant temps. Like clockwork, the ocean breezes begin to blow each afternoon between 2 and 3 p.m. Those winds can make you want to add an additional layer of clothing, but the winds die down around 5 p.m. again.
Evenings are cool and nights are normally blanket weather, though summer nights are perfect at around 60 to 65 degrees.
It doesn't rain much in Huntington Beach, so you generally don't need to pack an umbrella or rain coat when you visit, unless you specifically hear predictions of rain. It doesn't snow so you won't need boots or heavy coats for a visit, either. Maybe it sounds a little boring, but the weather, thanks to the Pacific Ocean that contributes to the beautiful beach scenes, is one of the reasons the area continues to grow.
