Wind and weather at Rio Vista
Seven days from the National Weather Service forecast for this stretch of coast. Each row is the range across the whole day, not a reading for one moment.
| Day | Wind | Gusts | Air | Sky | Rain |
|---|---|---|---|---|---|
| Today | 8–17 kn W | 28 kn | 56–80 °F | Clear | 0 % |
| Mon, September 14 | 8–10 kn W | 19 kn | 57–88 °F | Clear | 0 % |
| Tue, September 15 | 5–10 kn WSW | 16 kn | 57–88 °F | Clear | 0 % |
| Wed, September 16 | 7–11 kn WSW | 18 kn | 58–86 °F | Clear | 0 % |
| Thu, September 17 | 7–12 kn W | 21 kn | 59–87 °F | Clear | 0 % |
| Fri, September 18 | 9–13 kn WSW | 22 kn | 59–87 °F | Clear | 0 % |
| Sat, September 19 | 10–13 kn WSW | 23 kn | 58–84 °F | Mostly sunny | 1 % |

Boating, beach and fishing at Rio Vista
The same forecast as above, read for three things people do here. Each verdict names what decided it.
| Day | Boating | Beach | Fishing |
|---|---|---|---|
| Today | Poorgusts to 28 kn | Fairwind to 17 kn | Poorgusts to 28 kn |
| Mon, September 14 | Goodwind 10 kn or less | Good88 °F and dry | Goodlight wind, major window in daylight |
| Tue, September 15 | Goodwind 10 kn or less | Good88 °F and dry | Goodlight wind, major window in daylight |
| Wed, September 16 | Goodwind 11 kn or less | Good86 °F and dry | Goodlight wind, major window in daylight |
| Thu, September 17 | Fairgusts to 21 kn | Good87 °F and dry | Goodlight wind, major window in daylight |
| Fri, September 18 | Fairgusts to 22 kn | Good87 °F and dry | Goodlight wind, major window in daylight |
| Sat, September 19 | Fairgusts to 23 kn | Good84 °F and dry | Goodlight wind, major window in daylight |
Boating turns to Poor at the National Weather Service small craft threshold — sustained wind of 22 kn, gusts of 26 kn, or seas of 5 ft — and to Fair at 15 kn or 3 ft. Beach weighs air temperature, chance of rain and wind.Fishing asks whether the day is fishable at all and whether a solunar major window falls in daylight; it is not a prediction of what will bite. None of this replaces the marine forecast before you go out.

Solunar windows for Rio Vista
The moon pulls hardest when it is directly overhead or on the far side of the earth — the two major windows of about two hours. The shorter minor windows sit around moonrise and moonset. Anglers use them to pick a time on the water; they are computed from the moon's position, not measured.

Questions about Rio Vista tides
Answered from the same NOAA predictions as the table above; the solunar windows come from this page's own moon calculation. Where this page has no basis for an answer, there is no entry.
- What time is high tide in Rio Vista today?
- High water at 5:36 am (3.4 ft) and 5:48 pm (4.0 ft), local time in Rio Vista. Heights are feet above MLLW. Because the tide runs on the moon rather than the clock, each turn falls roughly 50 minutes later tomorrow — the seven-day table above carries the shift.
- What time is low tide in Rio Vista today?
- Low water at 12:15 am (0.7 ft) and 12:02 pm (0.8 ft), local time in Rio Vista. A height below zero is a minus tide: the water falls further than MLLW, the level the heights are counted from.
- How many tides does Rio Vista get in a day?
- Two high waters and two low waters on most days, a little over six hours apart. Over the seven days on this page that comes to 14 high waters and 14 low waters.
- What is the tidal range at Rio Vista?
- About 3.2 ft between today's lowest and highest water. Across the next seven days the water moves between 0.4 and 4.0 ft — a span of about 3.6 ft.
- Which tide station do these Rio Vista tide times come from?
- NOAA station 9415316 — a reference station, about 3.7 km from the centre of Rio Vista. The Sacramento River at Rio Vista, deep in the Delta. A reference station has its own long-running record, which is the strongest basis NOAA publishes. The predictions here are NOAA's, unchanged.
- What time zone are the Rio Vista tide times in?
- Every time on this page is clock time in Rio Vista — the America/Los_Angeles zone, daylight saving already applied. Nothing has to be converted, and no time is shown in UTC except the retrieval stamp at the foot of the page.
- When are the solunar windows at Rio Vista today?
- The major windows run 1:40 am to 3:40 am and 2:02 pm to 4:02 pm, with shorter minor windows around moonrise and moonset. They are computed from the moon's position over Rio Vista, not measured — anglers use them to pick a time on the water. The moon is 8% lit and waxing.
- How far ahead does this Rio Vista tide chart go?
- Seven days in the table, and every high and low water for September 2026 and October 2026 in the calendar below it. The page is rebuilt every morning, so the first day is always today.
