- ▲ High tide 4:49 pm 4.4 ft · coef. 74
↓ Falling The tide is falling. 6 h 20 min to low tide at 1:27 am.
Tide coefficient 76 for the 6:19 am high tide and 74 for the 4:49 pm high tide. Average coefficient. The water rises and falls 4.6 ft between the highest high and the lowest low: a large 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 July 13 (4.6 ft) and the lowest, on June 16 (-0.8 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 89, 3.8 ft range). The smallest, from October 17 to 18 (coefficient 50, 3.1 ft).

Where this tide comes from
Tides from the Rio Vista station (NOAA), 1.3 mi from Rio Vista. Times and heights are its predictions.

The sea at Rio Vista
Sea stateSea state: calm (rippled)
The waves you may find
- Most commonMost common0.0 ft
- Significant0.1 ft
- Highest expectedHighest0.1 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 0.1 ft. Before heading out, expect waves of up to 0.1 ft.
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 southeast and the wind blows from land out to sea: calm shore and clean waves, but watch the drift out to sea.
Wave height, next 7 daysWaves, next 7 days
Waves stay much the same all week. The biggest waves arrive on Sunday 1: 0.4 ft with a period of 2 s, from the north-northwest (smooth).

The best window, 9:50 am to 12:30 pm, combines slack water at low tide, little swell, light wind and the sun high. Also good from 4:20 pm to 5:30 pm, with slack water at high tide, little swell and light wind.
Slack water comes from the tide: in inlets, channels and between islands the water can keep running for an hour or two after. Ask the local dive shop.

The moon in Rio Vista
Moon phase and position
Today the moon is 226,426 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 1:50–3:50 am Major · the moon passes overhead · high activity
- 2:22–4:22 pm Major · the moon passes underfoot · high activity
- 10:12–11:12 am Minor · moonset · medium activity
- 7:28–8:28 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. Very shallow: the water doesn't reach 16 ft within 1 mi. Cast far from the beach, ideally around high tide.
- 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 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. There is land ahead (an island, a headland or the far shore) 1 mi out. The profile is turned slightly from the coast so it does not run into an island or a headland.
