Where this tide comes from
Broad Haven has no station of its own, so we use the tide at Milford Haven (Environment Agency), 5.5 mi away. On the open coast the difference is usually a few minutes and inches; inside estuaries, rivers and enclosed bays it can be much larger.
Station data attribution: This uses Environment Agency tide gauge data from the real-time data API (Beta): Milford Haven (E73024), https://environment.data.gov.uk/flood-monitoring/id/stations/E73024. Contains public sector information licensed under the Open Government Licence v3.0 (https://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/). Modified: harmonic constants fitted by TidePlanet from the 15-minute sea levels of 2025-10-29 to 2026-10-22 (356 days).
The sea at Broad Haven
Sea stateSea state: moderate
The waves you may find
- Most commonMost common2.4 ft
- Significant4.8 ft
- Highest expectedHighest9.6 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 9.6 ft. Before heading out, expect waves of up to 9.6 ft.
Wind on the coast and offshore
Cross-onshore wind. The coast faces west and the wind comes in from the sea at an angle: a bit more surf at the shore and drift along the coast, toward land.
Wave height, next 7 daysWaves, next 7 days
Waves ease over the next few days. The biggest waves arrive on Wednesday 28: 6.8 ft with a period of 9 s, from the west-southwest (moderate).
Water temperature

Diving in Broad Haven today
Diving and snorkeling today
Likely visibility: poor- Slack water around low tide (1:28 pm): little current from 1:00 pm to 1:50 pm
- 4.7 ft swell at 8 s from the west-southwest: strong surge on the bottom
- Moderate onshore wind (15 mph)
- 0.4 mph current toward the northeast, weak (model)
- Sun high: more light underwater
- Slack water today: low tide 1:06 am (12:40–1:30 am), high tide 7:09 am (6:50–7:30 am), low tide 1:28 pm (1:00–1:50 pm) and high tide 7:31 pm (7:10–7:50 pm)
- Likely visibility: poor. Swell (up to 8.5 ft at 9 s) and wind over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 56.8 °F: a 7 mm semi-dry suit, with hood, gloves and booties.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 5:35 pm. Waning gibbous (92%), rising at 5:45 pm: a bright night.
Your diving day at a glance
The best window, 12:30 pm to 2:20 pm, combines slack water at low tide, weak current and the sun high, though with some swell and moderate wind. Also worth a look from 7:10 am to 8:10 am, with slack water at high tide and weak current, though with some swell and moderate wind.
Slack water comes from the tide: in inlets, channels and between islands the water can keep running for an hour or two after. Ask the local dive shop.
Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

Moon phase and position
Today the moon is 226,451 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 12:43–2:43 am Major · the moon passes overhead · high activity
- 1:14–3:14 pm Major · the moon passes underfoot · high activity
- 10:09–11:09 am Minor · moonset · medium activity
- 5:15–6:15 pm Minor · moonrise · medium activity
According to solunar theory, fish feed more when the moon passes overhead or underfoot (major periods, about 2 h) and when it rises or sets (minor periods, 1 h). It works best around new and full moon.

For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 0.55 mi): cast far from the beach and fish the high tide, when there is more water close in.
- Swimming. A very gentle way in with plenty of shallow water, good for kids. At low tide the water can be far out.
- Diving. Shallow near shore: you only reach 33 ft at 0.95 mi. For dives deeper than 33 ft, go by boat.
Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide.
