About the tides at Harry Tappen Marina
Expect two roughly equal high tides a day at Hempstead Harbor, each arriving about 50 minutes later than the day before. With a mean range of about 7.3 ft, the shoreline here changes a lot between high and low water. That is larger than most New York stations on this site. From the average lower low to the average higher high, the difference is 7.9 ft. Over the next two weeks the biggest daily range, 10.4 ft, comes on October 27, and the smallest, 4.7 ft, tomorrow. Looking a year ahead, predictions peak at 9.4 ft on September 2 and bottom out at −1.7 ft on January 23.
Predictions for Harry Tappen Marina come from this station's own tide records. There is no live sensor, so the table shows forecast only. NOAA measured the tide here in 2014 to set up these predictions. The nearest other station is Glen Cove, 2 mi away, where high tide comes about 9 min later. For tidal currents, see Hempstead Harbor, off Glenwood Landing.
