SAN DIEGO — Tuesday afternoon high temperatures will be slightly above seasonal norms.

- Inland highs 67°-75°, normal around 70°.
- Mountain highs 61°-69°, normal around 53°.
- Desert highs 75°-80°, normal around 72°.
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.
A cut-off low pressure system from the Eastern Pacific Ocean will make its way onshore Friday into the weekend. Temperatures will drop Friday through the weekend, with coolest temperatures Saturday. Rain is also in the forecast, with best chances for some light rain to occur Saturday and primarily for the foothills and mountains.
