About Harry Tappen Marina, Hempstead Harbor tides
Tide predictions for Harry Tappen Marina, Hempstead Harbor come from NOAA station 8516607 (New York), 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.
Harry Tappen Marina, Hempstead Harbor 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.
