Where this tide comes from
Wells-next-the-Sea has no station of its own, so we use the tide at Cromer (Environment Agency), 19 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): Cromer (E71224), https://environment.data.gov.uk/flood-monitoring/id/stations/E71224.

The sea at Wells-next-the-Sea
Sea stateSea state: calm (rippled)
The waves you may find
- Most commonMost common0.2 ft
- Significant0.3 ft
- Highest expectedHighest0.7 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 0.7 ft. Before heading out, expect waves of up to 0.7 ft.
Wind on the coast and offshore
Cross-offshore wind. The coast faces north and the wind comes off the land at an angle: calmer water near the shore, and bait and boats 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: 4.4 ft with a period of 5 s, from the north-northeast (moderate).

Your diving day at a glance
The best window, 9:30 am to 12:30 pm, combines little swell, light wind, weak current and the sun high, though with tidal current. Also worth a look from 1:50 pm to 3:40 pm, with slack water at low tide, little swell and light wind, though with 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.

Solunar periods
Today's activity: medium- 1:22–3:22 am Major · the moon passes overhead · high activity

- 11:11 am–12:11 pm Minor · moonset · 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 2.1 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 2.9 mi. For dives deeper than 33 ft, go by boat.
