Tide times
High and low tides for your launch point, with the station they are predicted from.
Search for your launch point, or use your position, to see its highs and lows.
What you will get
- Every high tide and low tide, day by day, with the time each turns.
- The predicted height in feet for each one.
- The tide station the prediction is computed from — so you can judge how far your spot sits from it.
These are predictions, not measurements.
NOAA computes the astronomical tide — the water level produced by the moon, the sun and the earth's motion. In their words, they “cannot predict the effect that wind, rain, freshwater runoff, and other short-term meteorological events will have on the tides.”
That gap is not small. NOAA notes that winds blowing along the length of a bay “have been known to cause water levels to be 1-2 feet above or below the predicted tides.” If you are timing a shallow launch, a bar crossing or a bridge clearance, treat the number as the starting point and the wind as the correction.
A prediction also belongs to a station, not to wherever you are standing. The relationship between tide times and slack water “is unique to each location and cannot be determined from a generic ‘rule of thumb’.” The further your spot sits from the station named above, the more the times drift.
