Wind and weather at Belfast
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 | 0–6 kn SSW | 12 kn | 70–84 °F | Mostly sunny | 25 % |
| Mon, August 10 | 1–8 kn WNW | 15 kn | 63–83 °F | Partly cloudy | 52 % |
| Tue, August 11 | 0–7 kn WNW | 14 kn | 61–83 °F | Mostly sunny | 45 % |
| Wed, August 12 | 2–5 kn WNW | 10 kn | 60–81 °F | Mostly sunny | 11 % |
| Thu, August 13 | 0–7 kn WSW | 14 kn | 60–76 °F | Partly cloudy | 64 % |
| Fri, August 14 | 3–12 kn WNW | 22 kn | 57–76 °F | Mostly sunny | 23 % |
| Sat, August 15 | 4–10 kn NW | 19 kn | 55–77 °F | Mostly sunny | 5 % |

Boating, beach and fishing at Belfast
The same forecast as above, read for three things people do here. Each verdict names what decided it.
| Day | Boating | Beach | Fishing |
|---|---|---|---|
| Today | Goodwind 6 kn or less | Good84 °F and dry | Goodlight wind, major window in daylight |
| Mon, August 10 | Goodwind 8 kn or less | Fair52% chance of rain | Goodlight wind, major window in daylight |
| Tue, August 11 | Goodwind 7 kn or less | Fair45% chance of rain | Goodlight wind, major window in daylight |
| Wed, August 12 | Goodwind 5 kn or less | Good81 °F and dry | Goodlight wind, major window in daylight |
| Thu, August 13 | Goodwind 7 kn or less | Poor64% chance of rain | Fair64% chance of rain |
| Fri, August 14 | Fairgusts to 22 kn | Good76 °F and dry | Goodlight wind, major window in daylight |
| Sat, August 15 | Goodwind 10 kn or less | Good77 °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 Belfast
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 Belfast 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 Belfast today?
- High water at 8:08 am (9.6 ft) and 8:26 pm (11.5 ft), local time in Belfast. 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 Belfast today?
- Low water at 1:51 am (0.2 ft) and 2:03 pm (1.1 ft), local time in Belfast. 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 Belfast 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 Belfast?
- About 11.3 ft between today's lowest and highest water. Across the next seven days the water moves between -1.2 and 12.4 ft — a span of about 13.5 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 Belfast tide times come from?
- NOAA station 8415191 — a subordinate station, about 1.7 km from the centre of Belfast. Belfast on Penobscot Bay. Belfast in Northern Ireland is not this place. 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 Belfast tide times in?
- Every time on this page is clock time in Belfast — 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 Belfast today?
- The major windows run 8:39 am to 10:39 am and 9:12 pm to 11:12 pm, with shorter minor windows around moonrise and moonset. They are computed from the moon's position over Belfast, not measured — anglers use them to pick a time on the water. The moon is 13% lit and waning.
- How far ahead does this Belfast 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.
