↓ Falling The tide is falling. 7 h 35 min to low tide at 12:24 am.
Tide coefficient 76 for the 5:43 am high tide and 75 for the 4:05 pm high tide. Average coefficient. The water rises and falls 3.1 ft between the highest high and the lowest low: an average range for this place. 70 is an average tide here; 90 and above means spring tides; below 45, neap tides. What is the tide coefficient?
2026 extremes: the highest tide of the year is on June 15 (5.1 ft) and the lowest, on June 16 (-0.5 ft).
Mixed: two high and two low tides a day, but of quite different heights.
Heights above mean lower low water (MLLW), the zero of US nautical charts. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. MLLW
Tide coefficient and range in October
The biggest tides of the month came from October 8 to 10 (coefficient 87, 4.0 ft range). The smallest, from October 17 to 18 (coefficient 48, 3.3 ft).

Where this tide comes from
Tides from the Pittsburg station (NOAA), 1.3 mi from Diamond. Times and heights are its predictions. It is a NOAA subordinate station: its times and heights come from the Port Chicago reference station with the official corrections.

The sea at Diamond
Sea state
The wave model doesn't reach Diamond: it's on inland water (an estuary, sound or sheltered bay) or far from the open sea. Wind is still available right here.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
Offshore wind. The coast faces northeast and the wind blows from land out to sea: calm shore and clean waves, but watch the drift out to sea.

The moon in Diamond
Moon phase and position
Today the moon is 226,426 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 1:51–3:51 am Major · the moon passes overhead · high activity
- 2:22–4:22 pm Major · the moon passes underfoot · high activity
- 10:13–11:13 am Minor · moonset · medium activity
- 7:29–8:29 pm Minor · moonrise · medium activity
According to solunar theory, fish feed more when the moon passes overhead or underfoot (major periods, about 2 h) and when it rises or sets (minor periods, 1 h). It works best around new and full moon.

For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 2.7 mi): cast far from the beach and fish the high tide, when there is more water close in.
- Swimming. A very gentle way in with plenty of shallow water, good for kids. At low tide the water can be far out.
- Diving. Shallow: the water doesn't reach 33 ft within 3.1 mi. For deeper dives, take a boat farther out.
Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide. Where the bottom comes up to the surface there are shoals, rocks or an islet next to the profile.
