Wind and weather at Bay St. Louis
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 | 4–10 kn SW | 13 kn | 79–91 °F | Clear | 9 % |
| Thu, August 13 | 5–10 kn SSW | 14 kn | 79–92 °F | Clear | 5 % |
| Fri, August 14 | 4–9 kn SSW | 12 kn | 79–93 °F | Clear | 1 % |
| Sat, August 15 | 4–6 kn S | 9 kn | 79–94 °F | Mostly sunny | 6 % |
| Sun, August 16 | 3–7 kn S | 10 kn | 80–94 °F | Mostly sunny | 23 % |
| Mon, August 17 | 4–8 kn W | 11 kn | 80–95 °F | Mostly sunny | 17 % |

Boating, beach and fishing at Bay St. Louis
The same forecast as above, read for three things people do here. Each verdict names what decided it.
| Day | Boating | Beach | Fishing |
|---|---|---|---|
| Today | Goodwind 10 kn or less | Good91 °F and dry | Goodlight wind, major window in daylight |
| Thu, August 13 | Goodwind 10 kn or less | Good92 °F and dry | Goodlight wind, major window in daylight |
| Fri, August 14 | Goodwind 9 kn or less | Good93 °F and dry | Goodlight wind, major window in daylight |
| Sat, August 15 | Goodwind 6 kn or less | Good94 °F and dry | Goodlight wind, major window in daylight |
| Sun, August 16 | Goodwind 7 kn or less | Good94 °F and dry | Goodlight wind, major window in daylight |
| Mon, August 17 | Goodwind 8 kn or less | Good95 °F and dry | Goodlight wind, major window in daylight |
| Tue, August 18 | Goodwind 7 kn or less | Good95 °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 Bay St. Louis
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 Bay St. Louis tides
Answered from the same NOAA predictions as the table above. Where this page has no basis for an answer, there is no entry.
- What time is high tide in Bay St. Louis today?
- High water at 11:56 am (2.3 ft), local time in Bay St. Louis. 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 Bay St. Louis today?
- Low water at 10:09 pm (0.2 ft), local time in Bay St. Louis. 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 Bay St. Louis 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 9 high waters and 9 low waters. Where a date shows only three turns, the fourth has slipped past midnight and is listed under the following day.
- What is the tidal range at Bay St. Louis?
- About 2.2 ft between today's lowest and highest water. Across the next seven days the water moves between 0.2 and 2.3 ft — a span of about 2.2 ft. The range is widest around new and full moon and narrowest at the quarters, so it changes from week to week.
- Which tide station do these Bay St. Louis tide times come from?
- NOAA station 8747437, St. Louis Bay entrance — a reference station, about 3.2 km from the centre of Bay St. Louis. 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 Bay St. Louis tide times in?
- Every time on this page is clock time in Bay St. Louis — the America/Chicago 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 Bay St. Louis today?
- The major windows run 11:37 pm to 1:37 am and 12:04 pm to 2:04 pm, with shorter minor windows around moonrise and moonset. They are computed from the moon's position over Bay St. Louis, not measured — anglers use them to pick a time on the water. The moon is 0% lit and waning.
- How far ahead does this Bay St. Louis tide chart go?
- Seven days in the table, and every high and low water for August 2026 and September 2026 in the calendar below it. The page is rebuilt every morning, so the first day is always today.
