About Onion Key, Lostmans River tides
Tide predictions for Onion Key, Lostmans River come from NOAA station 8724863 (Florida), computed from long-term harmonic analysis of observed water levels. Heights are shown in feet relative to MLLW (Mean Lower Low Water) — the same datum used on US nautical charts — so they line up directly with charted depths.
Onion Key, Lostmans River typically sees a mixed semidiurnal tide, with two highs and two lows of differing heights each day. Use the curve above to time a harbor entrance, a beach walk, fishing a moving tide, or clearing a shallow bar — and remember that wind and pressure can push the real water level above or below prediction. The daily tidal range in the 30-day table shows how much water moves each day: bigger ranges around the new and full moon mean stronger currents.
Frequently asked
What time is high tide in Onion Key, Lostmans River today?+
Today (Wednesday, July 22), high tide at Onion Key, Lostmans River is at 10:09 AM (0.7 ft). Heights are referenced to MLLW (Mean Lower Low Water).
