Your day at a glance

The best window, 1:50 pm to 2:30 pm, combines the 1:27 pm high tide, a major period and some swell, though with rising pressure. Also worth a try from 1:10 am to 2:10 am, with the 1:10 am high tide, a major period, a light onshore breeze and some swell, though with rising pressure. Also worth a try from 7:20 am to 8:30 am, with the 8:23 am low tide, sunrise and some swell, though with rising pressure.

Species with the most records nearby: whiting, European plaice, small-spotted catshark and Atlantic horse mackerel. October is one of the months when these are seen most: Atlantic horse mackerel. What you can catch

Sea and waves

The sea at Calais

7-day waves

Waves 2.2 ft · 6.1 s from the west-southwest (252°)

The waves you may find

One wave in seven is higher than the significant height, and about 3 times a day one reaches 4.6 ft. Before heading out, expect waves of up to 4.6 ft.

Cross-shore wind. The coast faces north and the wind blows along the shore: drift and current run parallel to the beach.

The best window is 1:00 pm to 5:00 pm, though with small waves, a short-period swell, wind swell and cross-shore wind.

An estimate for this stretch of coast, not for a specific break: every beach or reef works its own way (its tide, bottom and angle). Check it when you get there.

Follow the flags and the lifeguards, and don’t paddle out if the surf is above your level: this score is a guide, not a substitute for what you see when you get there.

Your diving day at a glance

The best window, 3:30 pm to 4:30 pm, combines light wind and weak current, though with tidal current. Also worth a look from 10:30 am to 11:30 am, with light wind, weak current and the sun high, though with tidal 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.

Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

Solunar periods

Today's activity: high
  • 1:14–3:14 am Major · the moon passes overhead · high activity
  • 1:45–3:45 pm Major · the moon passes underfoot · high activity
  • 10:33–11:33 am Minor · moonset · medium activity
  • 5:52–6:52 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.

Water depth

Gentle slope

The bottom slopes gently: 16 ft deep 120 ft from shore and 33 ft at 0.8 mi. Right off the beach it already drops to about 27 ft.

From the shoreline (1.1 mi from Calais) out to sea, heading north.

How far from shore

  • 16 ft deep120 ft
  • 33 ft deep0.8 mi
  • 66 ft deep1.9 mi
  • 164 ft deepnot within 3.1 mi

For fishing, swimming and diving

  • Shore fishing. Deep water close in: about 27 ft just 330 ft out. Good for casting from rocks, jetties or the beach itself; current and surf hit harder here.
  • Swimming. The bottom drops quickly near the shore and you are soon out of your depth. Keep an eye on kids and weak swimmers.
  • Diving. Shallow near shore: you only reach 33 ft at 0.8 mi. For dives deeper than 33 ft, go by boat.

Right by the shore the bottom may drop even faster than shown. Where the bottom comes up to the surface there are shoals, rocks or an islet next to the profile.
