Tybee Island is semidiurnal — paired highs (7.1 and 8.2 ft today) and paired lows of similar size. This is a big-tide station: an average swing this week moves 7.4 ft, so the water line, current and structure change dramatically through a single cycle. A 8.5 ft swing — Tybee Island's biggest this table — runs from the 2:10 PM low on Thu Sep 10 into the next high. Tybee Island tops out at 8.4 ft (Wed Sep 9 7:27 PM) and bottoms at -0.2 ft (Thu Sep 10 2:10 PM).
Tybee Island mid-swing times below mark predicted peak flow on its 7.4 ft average cycle (why moving water matters):
Sea surface temperature 6 km away at Savannah Georgia Offshore is currently 30.8 °C (87.5 °F), 5.6 °C above the seasonal normal, from satellite and ocean-model data refreshed daily.
Tybee Island numbers: NOAA CO-OPS #8670892 (Tybee Light), 3.4 km off Tybee Island center; this open-water pick beat 4 closer-in candidates. On a coast that swings 7.4 ft, storm surge stacked on the 8.4 ft high is a real hazard at Tybee Island — predictions are astronomical only. All Tybee Island times station-local, refreshed 2026-09-08.
