Jupiter is semidiurnal — paired highs (3.2 and 3.0 ft today) and paired lows of similar size. The tide here is gentle — the water moves about 1.6 ft between high and low on an average swing this week, so timing matters less than on big-tide coasts. A 3.0 ft swing — Jupiter's biggest this table — runs from the 4:46 AM low on Mon Sep 14 into the next high. Jupiter tops out at 3.2 ft (Mon Sep 14 11:24 AM) and bottoms at 0.2 ft (Mon Sep 14 4:46 AM).
Jupiter mid-swing times below mark predicted peak flow on its 1.6 ft average cycle (why moving water matters):
Sea surface temperature 29 km away at Stuart Sailfish Alley is currently 29.2 °C (84.6 °F), 3.4 °C above the seasonal normal, from satellite and ocean-model data refreshed daily.
Jupiter numbers: NOAA CO-OPS #8722495 (Jupiter Inlet, South Jetty), 2.3 km off Jupiter center; this open-water pick beat 18 closer-in candidates. With only 1.6 ft of average swing at Jupiter, wind and pressure can move the real water line more than the tide itself does — treat these times as the schedule, not the whole story.
