Tide coefficient 91 for the 6:56 am high tide and 87 for the 7:22 pm high tide. Spring tides. The water rises and falls 22.1 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.

2026 extremes: the highest tide of the year is on September 12 (26.6 ft) and the lowest, on March 20 (1.3 ft).

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

Heights above chart datum: the lowest astronomical tide (LAT), the zero of nautical charts in Europe. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. chart datum (LAT)

Tide coefficient and range in October

The biggest tides of the month came from October 26 to 28 (coefficient 98, 23.6 ft range). The smallest, from October 19 to 20 (coefficient 29, 7.3 ft).

Where this tide comes from

B · Nearby station

Gorran Haven has no station of its own, so we use the tide at Port Isaac (TICON-4), 24 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.

How we calculate the tide

Sea and waves

The sea at Gorran Haven

7-day waves

Sea stateSea state: slight

Slight Douglas 3 · gentle breeze, Beaufort 3
Waves 2.7 ft · 7.5 s from the southwest (221°)
Swell 2.0 ft · 7.4 s from the southwest
Current 0.5 mph toward the WSW

The waves you may find

  • Most commonMost common1.3 ft
  • Significant2.7 ft
  • Highest expectedHighest5.4 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 5.4 ft. Before heading out, expect waves of up to 5.4 ft.

Wind on the coast and offshore

On the coast 6 mph SSW · gusts 11
Offshore (1.9 mi ENE)Offshore 8 mph SSW · gusts 11

Cross-onshore wind. The coast faces southeast 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.

Today’s surf at a glance

The best window is 7:00 am to 11:00 am, though with a short-period swell, wind swell and onshore 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, 7:00 am to 7:50 am, combines slack water at high tide and light wind, though with current. Also worth a look from 12:30 pm to 2:00 pm, with slack water at low tide 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: medium
  • 1:45–3:45 am Major · the moon passes overhead · high activity

  • 11:14 am–12:14 pm Minor · moonset · medium activity
  • 6:21–7:21 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

Deepens quickly

The bottom deepens quickly: 33 ft of water 950 ft from shore. It reaches 164 ft at 2.6 mi.

From the shoreline (0.55 mi from Gorran Haven) out to sea, heading southeast.

How far from shore

  • 16 ft deep600 ft
  • 33 ft deep950 ft
  • 66 ft deep0.35 mi
  • 164 ft deep2.6 mi

For fishing, swimming and diving

  • Shore fishing. 33 ft of water just 950 ft from shore: a good cast reaches deep water. Current and surf hit harder here.
  • Swimming. The water gets deeper little by little, but a few dozen yards out you can no longer stand.
  • Diving. Shore diving works here: 33 ft at 950 ft and 66 ft at 0.35 mi from shore.
