Where this tide comes from
Withernsea Pier has no station of its own, so we use the tide at Spurn Point (Environment Agency), 11 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 flood and river level data from the real-time data API (Beta): Spurn Point (L3370), https://environment.data.gov.uk/flood-monitoring/id/stations/L3370. 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 measured tidal levels of 2025-10-29 to 2026-10-22 (356 days).

Sea stateSea state: calm (rippled)
The waves you may find
- Most commonMost common0.1 ft
- Significant0.3 ft
- Highest expectedHighest0.6 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 0.6 ft. Before heading out, expect waves of up to 0.6 ft.
Wind on the coast and offshore
Offshore wind. The coast faces east and the wind blows from land out to sea: calm shore and clean waves, but watch the drift out to sea.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Monday 2: 3.3 ft with a period of 5 s, from the north-northeast (slight).

Your diving day at a glance
The best window, 11:40 am to 1:30 pm, combines slack water at low tide, little swell and the sun high, though with moderate wind and current.
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.

Moon phase and position
Today the moon is 226,451 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 12:22–2:22 am Major · the moon passes overhead · high activity
- 12:53–2:53 pm Major · the moon passes underfoot · high activity
- 10:01–11:01 am Minor · moonset · medium activity
- 4:39–5:39 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.
