Re: Typical Weather in December. Jun 23, 2012, 9:54 AM. December is pretty predictable....sunny and not too hot- around 28 during the day. Always a nice breeze from the ocean, so if you are on the beach under an umbrella, you don't feel hot, but also you can sit out in the sun and feel very warm. The ocean temp is also quite nice at that time.
