A tide chart for every stretch of coast people ask about, built from NOAA’s predictions rather than copied from another site. Each page names the NOAA station it uses and how far away it is, gives today’s highs and lows with a curve, the week and the month, and adds what an angler wants next to it: sunrise, the moon, and the solunar periods that line up with moving water.

Questions
Where do the tide times come from?
From NOAA’s Center for Operational Oceanographic Products and Services (CO-OPS), which publishes tide predictions for some 3,500 stations on the US coasts. Each place on this site uses the nearest prediction station, within 20 km, and names it.
What is MLLW?
Mean lower low water: the average of the lower of the two daily low tides over a 19-year cycle. US charts measure depth from it, so a tide of +2 ft means two feet more water than the charted depth, and a negative tide means less.
Why do high tides come about 50 minutes later each day?
Because the tide follows the moon, and the moon comes back over the same meridian about 50 minutes later every day. That is also why the solunar fishing periods shift by about the same amount.
Can I use these tide charts for navigation?
No. They are predictions of the astronomical tide; wind, pressure and river flow change the real water level. Use NOAA’s official predictions and charts for navigation.
