Wind and weather at St. Augustine Beach
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 | Waves |
|---|---|---|---|---|---|---|
| Today | 4–7 kn W | 10 kn | 76–86 °F | Partly cloudy | 42 % | 2 ft 9 s |
| Mon, September 14 | 4–8 kn WSW | 10 kn | 77–86 °F | Mostly sunny | 12 % | 2 ft 9 s |
| Tue, September 15 | 1–23 kn NE | 26 kn | 80–85 °F | Partly cloudy | 58 % | 6 ft 9 s |
| Wed, September 16 | 18–26 kn NE | 30 kn | 79–82 °F | Partly cloudy | 47 % | 8 ft 7 s |
| Thu, September 17 | 12–21 kn NE | 24 kn | 78–83 °F | Partly cloudy | 53 % | 8 ft 8 s |
| Fri, September 18 | 4–11 kn ENE | 13 kn | 78–83 °F | Partly cloudy | 51 % | 5 ft 8 s |

Boating, beach and fishing at St. Augustine Beach
The same forecast as above, read for three things people do here. Each verdict names what decided it.
| Day | Boating | Beach | Fishing |
|---|---|---|---|
| Today | Goodwind 7 kn or less | Fair42% chance of rain | Goodlight wind, major window in daylight |
| Mon, September 14 | Goodwind 8 kn or less | Good86 °F and dry | Goodlight wind, major window in daylight |
| Tue, September 15 | Poor6 ft of sea | Poorwind to 23 kn | Poorgusts to 26 kn |
| Wed, September 16 | Poor8 ft of sea | Poorwind to 26 kn | Poorgusts to 30 kn |
| Thu, September 17 | Poor8 ft of sea | Poorwind to 21 kn | Fairwind to 21 kn |
| Fri, September 18 | Poor5 ft of sea | Fair51% chance of rain | Goodlight wind, major window in daylight |
| Sat, September 19 | Fair3 ft of sea | Fair48% chance of rain | 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 St. Augustine Beach
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 St. Augustine Beach 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 St. Augustine Beach today?
- High water at 10:18 am (5.7 ft) and 10:37 pm (5.1 ft), local time in St. Augustine Beach. 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 St. Augustine Beach today?
- Low water at 3:55 am (0.1 ft) and 4:28 pm (0.4 ft), local time in St. Augustine Beach. 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 St. Augustine Beach 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 13 high waters and 14 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 St. Augustine Beach?
- About 5.6 ft between today's lowest and highest water. Across the next seven days the water moves between 0.1 and 5.7 ft — a span of about 5.6 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 St. Augustine Beach tide times come from?
- NOAA station 8720587 — a reference station, about 1.8 km from the centre of St. Augustine Beach. 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 St. Augustine Beach tide times in?
- Every time on this page is clock time in St. Augustine Beach — the America/New_York 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 St. Augustine Beach today?
- The major windows run 1:53 am to 3:53 am and 2:15 pm to 4:15 pm, with shorter minor windows around moonrise and moonset. They are computed from the moon's position over St. Augustine Beach, not measured — anglers use them to pick a time on the water. The moon is 7% lit and waxing.
- How far ahead does this St. Augustine Beach 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.
