Tide coefficient 85 for the 3:11 am high tide and 83 for the 3:32 pm high tide. Average coefficient. The water rises and falls 16.3 ft between the highest high and the lowest low: a large 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 27 (20.2 ft) and the lowest, on February 21 (1.1 ft).

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

Tide coefficient and range in October

The biggest tides of the month came from October 10 to 12 (coefficient 93, 17.1 ft range). The smallest, from October 5 to 6 (coefficient 53, 9.3 ft).

How we calculate the tide

Sea and waves

The sea at Ritthem

7-day waves

Sea stateSea state: smooth

Smooth Douglas 2 · gentle breeze, Beaufort 3
Waves 0.9 ft · 3.6 s from the west (273°)
Swell 0.8 ft · 3.1 s from the west
Current 0.5 mph toward the ESE

The waves you may find

  • Most commonMost common0.4 ft
  • Significant0.9 ft
  • Highest expectedHighest1.8 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 1.8 ft. Before heading out, expect waves of up to 1.8 ft.

Wind on the coast and offshore

On the coast 14 mph SW · gusts 17
Offshore (6.4 mi WNW)Offshore 9 mph SW · gusts 16

Cross-onshore wind. The coast faces west and the wind comes in from the sea at an angle: a bit more surf at the shore and drift along the coast, toward land.

Wave height, next 7 daysWaves, next 7 days

Waves stay much the same all week. The biggest waves arrive on Monday 2: 1.6 ft with a period of 4 s, from the north (smooth).

Water temperature

Water now55.8 °F
Today 55.8–55.8 °F air: 49 / 57 °F
Satellite (yesterday) 58.6 °F measured 0.9 mi away

The satellite measured 2.9 °F more yesterday 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, 8:30 am to 10:10 am, combines slack water at low tide, little swell and weak current, though with moderate wind. Also worth a look from 3:10 pm to 3:50 pm, with slack water at high 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.

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
  • 1:07–3:07 am Major · the moon passes overhead · high activity
  • 1:38–3:38 pm Major · the moon passes underfoot · high activity
  • 10:29–11:29 am Minor · moonset · medium activity
  • 5:41–6:41 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: you need to go 0.95 mi out for 33 ft of water.

From the shoreline (0.75 mi from Ritthem) out to sea, heading west.

How far from shore

  • 16 ft deep0.95 mi
  • 33 ft deep0.95 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 0.95 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 0.95 mi. For dives deeper than 33 ft, go by boat.

Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide. Where the bottom comes up to the surface there are shoals, rocks or an islet next to the profile.
