  • Swimming Use care · 5.2 ft

    5.2 ft waves every 9 s: swim with care and stay where you can stand. High rip current risk. If you're caught in a rip current, don't swim against it: swim parallel to shore and wave for help. Always follow the lifeguard's flags.

  • ▲ High tide 6:33 pm 17.3 ft · coef. 87

↓ Falling The tide is falling. 5 h 11 min to low tide at 1:05 pm.

Tide coefficient 90 for the 6:11 am high tide and 87 for the 6:33 pm high tide. Spring tides. The water rises and falls 15.5 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 March 21 (18.4 ft) and the lowest, on August 14 (0.9 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 95, 16.2 ft range). The smallest, from October 19 to 20 (coefficient 33, 5.9 ft).

Where this tide comes from

B · Nearby station

Pentreath has no station of its own, so we use the tide at Newlyn (Environment Agency), 17 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.

Station data attribution: This uses Environment Agency tide gauge data from the real-time data API (Beta): Newlyn (E72224), https://environment.data.gov.uk/flood-monitoring/id/stations/E72224. Contains public sector information licensed under the Open Government Licence v3.0 (https://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/). Modified: harmonic constants fitted by TidePlanet from the 15-minute sea levels of 2025-10-29 to 2026-10-22 (352 days).

How we calculate the tide

Sea and waves

The sea at Pentreath

7-day waves

Sea stateSea state: moderate

Moderate Douglas 4 · moderate breeze, Beaufort 4
Waves 5.2 ft · 9.0 s from the west-southwest (253°)
Swell 4.9 ft · 7.7 s from the west-southwest
Current 1.4 mph toward the E

The waves you may find

  • Most commonMost common2.6 ft
  • Significant5.2 ft
  • Highest expectedHighest10 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 10 ft. Before heading out, expect waves of up to 10 ft.

Wind on the coast and offshore

On the coast 15 mph SSE · gusts 18

The model doesn't separate offshore wind here: it's the same as on the coast.

Cross-onshore wind. The coast faces south 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.

The best window, 7:00 am to 8:00 am, has a good size, though with a short-period swell and onshore wind. 9:00 am to 1:00 pm can also work, with a good size, though with a short-period 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.

Your diving day at a glance

The best window, 2:30 pm to 3:30 pm, combines weak current and the sun high, though with tidal current, some swell and moderate wind. Also worth a look from 8:30 am to 9:30 am, with weak current, though with tidal current, some swell and moderate wind.

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.

Solunar periods

Today's activity: medium
  • 1:47–3:47 am Major · the moon passes overhead · high activity
  • 2:19–4:19 pm Major · the moon passes underfoot · high activity
  • 11:14 am–12:14 pm Minor · moonset · medium activity
  • 6:25–7:25 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 0.3 mi from shore. It reaches 164 ft at 2.8 mi.

From the shoreline out to sea, heading south.

How far from shore

  • 16 ft deep900 ft
  • 33 ft deep0.3 mi
  • 66 ft deep1 mi
  • 164 ft deep2.8 mi

For fishing, swimming and diving

  • Shore fishing. Deep water close in: about 6.6 ft just 330 ft out. Good for casting from rocks, jetties or the beach itself; 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. 33 ft deep 0.3 mi from shore; 66 ft is far out (1 mi): for deeper dives, go by boat.
