A 5.8 ft swing — Santa Cruz's biggest this table — runs from the 2:26 PM high on Sat Oct 31 into the next low. Santa Cruz tops out at 5.7 ft (Sat Nov 7 8:22 AM) and bottoms at -0.5 ft (Sat Oct 31 10:16 PM).
Santa Cruz mid-swing times below mark predicted peak flow on its 3.4 ft average cycle (why moving water matters):
Sea surface temperature 18 km away at Monterey Bay Submarine Canyon is currently 18.6 °C (65.4 °F), 2.6 °C above the seasonal normal, from satellite and ocean-model data refreshed daily.
Santa Cruz numbers: NOAA CO-OPS #9413745 (Santa Cruz, Monterey Bay), 10.5 km off Santa Cruz center. Onshore wind or a storm can push real water at Santa Cruz above the 5.7 ft predicted peak; offshore wind can hold it under. All Santa Cruz times station-local, refreshed 2026-10-30.
