Wind and weather at Aptos
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 | 2–12 kn W | 17 kn | 56–63 °F | Partly cloudy | 0 % | 4 ft 8 s |
| Wed, August 19 | 2–11 kn W | 18 kn | 58–62 °F | Mostly cloudy | 0 % | 4 ft 8 s |
| Thu, August 20 | 4–14 kn NW | 20 kn | 58–63 °F | Mostly cloudy | 0 % | 4 ft 9 s |
| Fri, August 21 | 6–18 kn WNW | 26 kn | 58–69 °F | Mostly cloudy | 0 % | 3 ft 8 s |
| Sat, August 22 | 4–11 kn NNW | 21 kn | 58–69 °F | Partly cloudy | 0 % | 3 ft 8 s |
| Sun, August 23 | 1–6 kn W | 15 kn | 57–65 °F | Partly cloudy | 0 % | 2 ft 8 s |

Boating, beach and fishing at Aptos
The same forecast as above, read for three things people do here. Each verdict names what decided it.
| Day | Boating | Beach | Fishing |
|---|---|---|---|
| Today | Fair4 ft of sea | Pooronly 63 °F | Goodlight wind, major window in daylight |
| Wed, August 19 | Fair4 ft of sea | Pooronly 62 °F | Goodlight wind, major window in daylight |
| Thu, August 20 | Fair4 ft of sea | Pooronly 63 °F | Goodlight wind, major window in daylight |
| Fri, August 21 | Poorgusts to 26 kn | Fair69 °F | Poorgusts to 26 kn |
| Sat, August 22 | Fair3 ft of sea | Fair69 °F | Goodlight wind, major window in daylight |
| Sun, August 23 | Goodwind 6 kn or less | Fair65 °F | Goodlight wind, major window in daylight |
| Mon, August 24 | Goodwind 7 kn or less | Fair65 °F | 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 Aptos
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 Aptos 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 Aptos today?
- High water at 3:21 am (3.4 ft) and 3:14 pm (5.0 ft), local time in Aptos. 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 Aptos today?
- Low water at 8:24 am (2.1 ft) and 10:31 pm (1.2 ft), local time in Aptos. 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 Aptos 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 13 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 Aptos?
- About 3.8 ft between today's lowest and highest water. Across the next seven days the water moves between 0.1 and 5.4 ft — a span of about 5.3 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 Aptos tide times come from?
- NOAA station 9413745 — a subordinate station. Santa Cruz station on the open waters of Monterey Bay, 11.6 km north-west — the nearest station on the same open coast. The closer Elkhorn Slough stations sit inside a tidal slough, not on the bay itself. A subordinate station carries no gauge of its own: NOAA publishes its times as an offset from a nearby reference station, which is how the agency itself issues them. The predictions here are NOAA's, unchanged.
- What time zone are the Aptos tide times in?
- Every time on this page is clock time in Aptos — 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 Aptos today?
- The major windows run 4:35 am to 6:35 am and 4:58 pm to 6:58 pm, with shorter minor windows around moonrise and moonset. They are computed from the moon's position over Aptos, not measured — anglers use them to pick a time on the water. The moon is 37% lit and waxing.
- How far ahead does this Aptos 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.
