Today in San Francisco County, marine conditions feature steady northwest winds moving across the coastal waters at 15 to 20 knots, pushing afternoon air temperatures to a cool high near 62° following a morning low of 53°. Data provided by the National Oceanic and Atmospheric Administration indicates that regional buoys are currently logging a primary northwest swell tracking at 7 feet with an 8-second period, running alongside a softer secondary southern swell measured at 2 feet with a 14-second interval. Near the San Francisco Bar and open beaches, this translates to average wave sizes holding steady between 3 and 5 feet, creating steep, choppy, and energetic sea surfaces throughout the afternoon. Tidal movements for the day show that an early morning low tide dropped to minus 1.52 feet at 5:18 AM, which was followed by a moderate high tide of 4.86 feet at 12:41 PM. The ocean will reach its next low tide of 3.06 feet at 4:49 PM this afternoon before pushing up significantly toward a robust late-night high tide of 7.20 feet at 11:01 PM.
