At the beaches, water temperature is 57°-60° with a moderate rip current risk. Waves are 2'-4' from a west-northwest swell and a slowly building southwest swell. The UV index will peak at 5 (moderate).

The marine layer has deepened overnight, resulting in a higher cloud layer. Morning fog will be limited to higher inland areas as well as the mountain foothills. Morning clouds will dissipate by mid-morning for a mostly clear and pleasant afternoon with passing high clouds. Weak offshore flow will keep humidity levels fairly dry, with mild conditions near the coast. Remember to wear sunscreen if you are planning on enjoying the beautiful outdoors.

THE WEEK AHEAD:

Weak onshore flow overnight will bring low clouds and potential fog to areas west of the mountains through Thursday. Fair and mild weather will continue after the morning clouds dissipate. Weak ridging will increase temperatures through Thursday in addition to increasing offshore flow.

The offshore flow event will peak Thursday, with wind gusts up to 40 mph in the most wind prone locations. An approaching low pressure system will switch the wind flow to onshore for Friday.
