New Hampshire tides: common questions

What time is high tide in New Hampshire today?

High tide arrives at a different time at each station. Atlantic Heights reaches 8.2 ft at 2:01 pm; Dover Point reaches 7.0 ft at 2:57 pm; Dover, Cocheco River reaches 7.66 ft at 3:05 pm. The table above lists the next high and the next low for all 9 New Hampshire stations.

Where is the biggest tidal range in New Hampshire?

Fort Point, where high and low water differ by 9.5 ft today. The smallest of the 9 New Hampshire stations with a range today is Dover Point at 7.0 ft. Range varies along a coast because the shape of a bay or estuary amplifies or damps the same ocean tide.

Is there a minus tide in New Hampshire today?

Yes, at Atlantic Heights, Dover Point, Fort Point and 5 others. The lowest is -0.02 ft at 7:53 pm. A minus tide is water below mean lower low water, the zero point for US predictions, and it exposes ground that is normally covered.

Are New Hampshire tides semidiurnal or diurnal?

All 9 New Hampshire stations here are semidiurnal, which means two highs and two lows a day, of roughly equal size. Each station page classifies itself from its own predictions rather than from a regional rule, because the pattern changes along a single coast.

How accurate are these New Hampshire tide predictions?

NOAA states roughly ten minutes on timing and half a foot on height for a reference station in ordinary weather. 2 of the 9 stations here are reference stations; the rest are subordinate, with times and heights derived from one by a published offset, so expect a little more spread. Weather is the bigger factor either way. A storm surge or a strong onshore wind can raise real water well above the prediction, which is astronomy only.
