San Francisco woke up today to a classic June mix of cool, mostly cloudy skies and mid 50s temperatures near the water, while sunshine started to punch through inland. Along the shoreline, highs should reach near 74°F this afternoon, with noticeably hotter conditions farther from the water. Southwest winds will strengthen through the day, with gusts up to about 18 mph in exposed spots along the bayfront.
What To Watch Tonight
A Coastal Flood Advisory is in effect along the San Francisco Bay shoreline through 3:00 AM next Wednesday, paired with a Beach Hazards Statement from early tomorrow through next Wednesday, warning of dangerous sneaker waves and strong rip currents, according to NWS San Francisco. Forecasters expect the San Francisco tidal gauge to run roughly 1.9 feet above normal around 10:20 PM today and near 2.0 feet above normal around 11:10 PM tomorrow, making those nightly high tides the main coastal trouble spot this weekend. At those levels, water can spill into low-lying lots, parks, and roads during peak tides.
Where Flooding And Sneaker Waves Are Most Likely
Low-lying bayside areas, including stretches of the Embarcadero, portions of Bayshore, and waterfront parks, are the most vulnerable to minor flooding during the late-night high tides. Along the outer Pacific coast, the bigger concern is in the surf zone, with elevated risk from sneaker waves and strong rip currents. Staying off jetties and rocks and keeping a healthy distance from the waterline is strongly advised. If you need to be near the shoreline after dark, build in extra time and follow any posted closures or detours.
Afternoon Winds And Interior Heat
While the immediate coast hangs onto the natural air conditioning, much of the interior East Bay and South Bay remains under a Heat Advisory through 7:00 PM today, with inland highs pushing into the 80s and up toward 100°F in the far inland valleys, per NWS San Francisco. Southwest winds of 2 to 13 mph, with gusts near 18 mph, will help stir the air and trim temperatures a bit later in the day. Residents are urged to stay hydrated, shift strenuous activity to cooler hours, and tap local cooling resources if they are sensitive to heat.
Tips And Where To Check
Keep children and pets well back from the high tide line, never turn your back to the ocean, and avoid driving through standing water, no matter how shallow it looks. For up-to-the-minute tide predictions, check the NOAA San Francisco tide gauge, and review the latest from NWS San Francisco before heading to the shoreline. Evening commuters on bayside roads should plan for possible minor delays and follow safety instructions from local authorities.
