Blue Heron Bridge mid-swing times below mark predicted peak flow on its 3.0 ft average cycle (why moving water matters):
Sea surface temperature 18 km away at Palm Beach Offshore is currently 30.9 °C (87.5 °F), 5.0 °C above the seasonal normal, from satellite and ocean-model data refreshed daily.
Blue Heron Bridge numbers: NOAA CO-OPS #8722588 (Port of Palm Beach), 1.6 km off Blue Heron Bridge center; this open-water pick beat 15 closer-in candidates. Onshore wind or a storm can push real water at Blue Heron Bridge above the 3.8 ft predicted peak; offshore wind can hold it under. All Blue Heron Bridge times station-local, refreshed 2026-09-08.
