Wind and weather at Port Jefferson
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 | 4–7 kn SE | 12 kn | 70–77 °F | Mostly cloudy | 97 % |
| Mon, September 14 | 5–13 kn NNW | 20 kn | 66–73 °F | Mostly sunny | 30 % |
| Tue, September 15 | 4–11 kn NNE | 15 kn | 61–69 °F | Clear | 0 % |
| Wed, September 16 | 3–6 kn S | 9 kn | 64–75 °F | Mostly sunny | 0 % |
| Thu, September 17 | 2–6 kn S | 11 kn | 67–77 °F | Partly cloudy | 19 % |
| Fri, September 18 | 5–8 kn W | 14 kn | 68–77 °F | Partly cloudy | 27 % |

Boating, beach and fishing at Port Jefferson
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 | Poor97% chance of rain | Fair97% chance of rain |
| Mon, September 14 | Fairgusts to 20 kn | Fair30% chance of rain | Goodlight wind, major window in daylight |
| Tue, September 15 | Goodwind 11 kn or less | Fair69 °F | Goodlight wind, major window in daylight |
| Wed, September 16 | Goodwind 6 kn or less | Good75 °F and dry | Goodlight wind, major window in daylight |
| Thu, September 17 | Goodwind 6 kn or less | Good77 °F and dry | Goodlight wind, major window in daylight |
| Fri, September 18 | Goodwind 8 kn or less | Good77 °F and dry | Goodlight wind, major window in daylight |
| Sat, September 19 | Goodwind 9 kn or less | Fair39% 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 Port Jefferson
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 Port Jefferson 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 Port Jefferson today?
- High water at 1:11 am (7.2 ft) and 1:31 pm (7.7 ft), local time in Port Jefferson. 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 Port Jefferson today?
- Low water at 7:22 am (0.1 ft) and 7:53 pm (0.1 ft), local time in Port Jefferson. 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 Port Jefferson 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.
- What is the tidal range at Port Jefferson?
- About 7.7 ft between today's lowest and highest water. Across the next seven days the water moves between 0.1 and 7.7 ft — a span of about 7.7 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 Port Jefferson tide times come from?
- NOAA station 8514560 — a reference station, about 2.2 km from the centre of Port Jefferson. 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 Port Jefferson tide times in?
- Every time on this page is clock time in Port Jefferson — 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 Port Jefferson today?
- The major windows run 1:19 am to 3:19 am and 1:42 pm to 3:42 pm, with shorter minor windows around moonrise and moonset. They are computed from the moon's position over Port Jefferson, not measured — anglers use them to pick a time on the water. The moon is 7% lit and waxing.
- How far ahead does this Port Jefferson 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.
