↑ Rising The tide is rising. 56 min to high tide at 1:44 am.

Tide coefficient 76 for the 1:44 am high tide and 75 for the 2:07 pm high tide. Average coefficient. The water rises and falls 10.2 ft between the highest high and the lowest low: an average range for this place. 70 is an average tide here; 90 and above means spring tides; below 45, neap tides. What is the tide coefficient?

2026 extremes: the highest tide of the year is on October 10 (13.7 ft) and the lowest, on April 18 (0.9 ft).

Semidiurnal: two high and two low tides a day, of similar height.

How we calculate the tide

Sea and waves

The sea at Termunterzijl

7-day waves

Sea stateSea state: smooth

Smooth Douglas 2 · gentle breeze, Beaufort 3
Waves 0.7 ft · 3.1 s from the west-southwest (253°)
Swell 0.5 ft · 2.8 s from the west
Current 0.3 mph toward the NNE

The waves you may find

  • Most commonMost common0.4 ft
  • Significant0.7 ft
  • Highest expectedHighest1.5 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 1.5 ft. Before heading out, expect waves of up to 1.5 ft.

Wind on the coast and offshore

On the coast 9 mph SW · gusts 15
Offshore (14 mi N)Offshore 12 mph WSW · gusts 18

Offshore wind. The coast faces north 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: 1.8 ft with a period of 5 s, from the north (slight).

Water temperature

Water now53.6 °F
Today 53.2–53.8 °F air: 48 / 58 °F
Satellite (2 days ago) 57.2 °F measured 0.7 mi away

The satellite measured 3.6 °F more 2 days ago than the model gives now: the water is probably warmer than the forecast says.

Water temperature changes how fish behave: in very cold or very warm water they feed less. The water is steady these days, with no sudden changes.

Water about normal for late October.

Your diving day at a glance

The best window, 11:50 am to 2:50 pm, combines slack water at high tide, little swell, light wind, weak current and the sun high. Also good from 7:20 am to 8:10 am, with slack water at low tide, little swell, light wind and weak 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.

  • 1:56–3:56 am Major · the moon passes overhead · high activity

  • 11:48 am–12:48 pm Minor · moonset · medium activity
  • 6:08–7:08 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

Shallow, gradual

Shallow, gradual bottom: 16 ft at 0.8 mi from shore and 9.2 ft at 3.1 mi.

From the shoreline (1,100 ft from Termunterzijl) out to sea, heading northwest.

How far from shore

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

For fishing, swimming and diving

  • Shore fishing. Shallow, gradual bottom (16 ft at 0.8 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.

Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide. The profile is turned slightly from the coast so it does not run into an island or a headland.
