San Diego rolled in today, under mostly clear skies and a brisk start in the upper 40s, with a quick warm-up already in the cards. Skies stay mostly sunny through the day, with coastal highs near 76°F and inland spots running a few degrees warmer. Expect bright afternoons and noticeably lower humidity compared with the last few weeks.
Afternoon Winds Pick Up
By afternoon, north winds are set to develop, especially along coastal bluffs and canyon mouths. Forecasts call for sustained breezes around 0–15 mph, with gusts up to 25 mph later in the day. The National Weather Service San Diego office notes that those gusts will be most likely toward the latter part of the afternoon, so anything lightweight in the yard or on the sand is fair game to get tossed around.

Coast Versus Inland
The warming trend gives inland valleys the edge, with highs running well above seasonal averages as the week goes on, while coastal neighborhoods hover in the mid-70s. Some inland pockets could end up 10–20 degrees above normal later in the week, a pattern outlined in coverage from the Times of San Diego. For outdoor plans, coastal mornings will be the most comfortable slice of the day.
What To Expect Through The Week
High pressure keeps conditions dry and warm through Friday, while a weak onshore flow sliding back in later in the week will start to thicken the nighttime marine layer, bringing cooler mornings by Thursday and Friday. Forecasters are not expecting hazardous marine conditions through Friday, and a gradual cooling trend may start to take hold next weekend. Light layers will still come in handy for the morning commute, and it is worth checking updated forecasts before committing to any late-evening beach time.
