San Diego is semidiurnal — paired highs (3.7 and 5.7 ft today) and paired lows of similar size. An average swing here this week moves 4.0 ft of water. A 6.7 ft swing — San Diego's biggest this table — runs from the 7:19 AM high on Sat Nov 7 into the next low. San Diego tops out at 6.5 ft (Sat Nov 7 7:19 AM) and bottoms at -0.2 ft (Sat Nov 7 2:07 PM).
San Diego mid-swing times below mark predicted peak flow on its 4.0 ft average cycle (why moving water matters):
Sea surface temperature 17 km away at San Diego Yellowfin Banks is currently 24.5 °C (76.1 °F), 1.7 °C above the seasonal normal, from satellite and ocean-model data refreshed daily.
San Diego numbers: NOAA CO-OPS #9410170 (San Diego (broadway)), 1.3 km off San Diego center; this open-water pick beat 6 closer-in candidates. Onshore wind or a storm can push real water at San Diego above the 6.5 ft predicted peak; offshore wind can hold it under. All San Diego times station-local, refreshed 2026-10-30.
