Where this tide comes from
Tides from the Harwich station (Environment Agency), 1.0 mi from Dovercourt. Times and heights are its predictions.

The sea at Dovercourt
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 southeast 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 Tuesday 3: 2.7 ft with a period of 5 s, from the northeast (slight).

Solunar periods
Today's activity: medium- 1:20–3:20 am Major · the moon passes overhead · high 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 1.5 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: the water doesn't reach 33 ft within 3.1 mi. For deeper dives, take a boat farther out.
