How to read it
-
Every high & low tide
All daily tides, not just the biggest ones. High water above the curve, low water below, in local time.
-
Heights in feet
Each tide shows its height, so you can spot the extreme lows and big highs at a glance.
-
Tidal coefficient
One number per tide that tells you how strong it is. The higher it is, the bigger the swing between high and low.
-
Moon phases
New moon, first quarter, full moon and last quarter, placed right on the tide curve.
Three seasons, three colors: Jan – Apr May – Aug Sep – Dec
