San Jose rolled into Saturday under a gray blanket of low clouds and patchy fog, with temperatures hovering near 55°F at Mineta San José International Airport. The familiar marine layer is hanging along the coast and in some low-lying inland spots through the morning, before inland neighborhoods break out into the low 70s by midafternoon.
Foggy Mornings, Sunny Afternoons
Patchy fog is expected through about 9 a.m., then skies should open up to partly sunny to mostly sunny conditions, with an afternoon high near 72°F. Inland areas away from the immediate shoreline will run warmest, while spots right along the bay likely stay a bit cooler. Northwest winds stay light early, then increase to around 5–10 mph later in the day.
Coastal Hazards And Boaters
Out at the coast, a long-period northwesterly swell is setting up the kind of day where the ocean looks inviting but can turn nasty in a hurry. Dangerous sneaker waves and strong rip currents are expected along Pacific beaches through Sunday evening, and seas offshore will be rough for smaller vessels. Small craft should be ready for choppy conditions and follow local advisories, according to the National Weather Service.

Rain Chances Early Next Week
A weak system may brush the region Monday into Tuesday, bringing a slight chance of light, spotty rain mainly along the coast and over the hills. Forecasters say confidence in any rain is low. If the wetter model scenarios play out, any measurable totals would still be on the light side; otherwise, expect only drizzle or an isolated sprinkle or two, according to the National Weather Service.
Practical Tips
For the morning drive, plan on slower going where fog cuts visibility. Use low beams, give yourself extra time even for quick trips, and watch for damp pavement, especially near the water. Beachgoers and boaters should stay well above the surf line, keep an eye on the waves, and check local advisories before heading out.
