What is the tide coefficient?
2026 extremes: the highest tide of the year is on December 26 (17.0 ft) and the lowest, on April 18 (0.8 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 101, 14.9 ft range). The smallest, on October 20 (coefficient 30, 4.1 ft).

Where this tide comes from
Inner Hope has no station of its own, so we use the tide at Dartmouth (Environment Agency), 14 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 flood and river level data from the real-time data API (Beta): Dartmouth (46154), https://environment.data.gov.uk/flood-monitoring/id/stations/46154. 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 measured tidal levels of 2025-10-29 to 2026-10-22 (356 days).
The sea at Inner Hope
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.5 ft
- Significant3.0 ft
- Highest expectedHighest6.0 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 6.0 ft. Before heading out, expect waves of up to 6.0 ft.
Wind on the coast and offshore
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.
Wave height, next 7 daysWaves, next 7 days
Waves stay much the same all week. The biggest waves arrive on Thursday 29: 3.7 ft with a period of 9 s, from the southwest (slight).
Water temperature
Water temperature →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.

- First or last light of the day
- Rising tide (high tide at 7:58 am)
- Light: First light 6:27 am · sunrise 7:01 am · sunset 4:57 pm · last light 5:31 pm
- Tide: low 1:31 am (2.3 ft), high 7:58 am (16.4 ft), low 1:51 pm (2.5 ft) and high 8:21 pm (15.7 ft). Every break has its own tide: some work at low tide and others at high tide. The tide doesn’t change the score here.

Today’s surf at a glance
The best window, 6:27 am to 8:00 am, has a good size.
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.
Diving in Inner Hope today
Diving and snorkeling today
Likely visibility: fair- Slack water around high tide (7:58 am): little current from 7:40 am to 8:20 am
- 2.5 ft swell at 8 s from the west-southwest: some surge on the bottom
- Light onshore wind (9 mph)
- 0.2 mph current toward the east-southeast, weak (model)
- Daylight
- Slack water today: low tide 1:31 am (1:16–1:46 am), high tide 7:58 am (7:40–8:20 am), low tide 1:51 pm (1:36–2:06 pm) and high tide 8:21 pm (8:00–8:50 pm)
- Likely visibility: fair. Swell (up to 5.6 ft at 9 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 59.2 °F: a 7 mm wetsuit, with hood and booties.
- Snorkeling: doable, with some waves or wind.
- Night dive: dark from 5:31 pm. Waning gibbous (85%), rising at 6:47 pm: a bright night.
Your diving day at a glance
The best window, 7:30 am to 9:30 am, combines slack water at high tide, light wind and weak current. Also worth a look from 1:30 pm to 2:10 pm, with slack water at low tide, light wind and the sun high, though with 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.

The moon in Inner Hope
Moon phase and position
Today the moon is 226,641 mi away and looks 32′ 45″ across.
Solunar periods
Today's activity: medium- 1:41–3:41 am Major · the moon passes overhead · high activity
- 2:14–4:14 pm Major · the moon passes underfoot · high activity
- 11:10 am–12:10 pm Minor · moonset · medium activity
- 6:17–7:17 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.

For fishing, swimming and diving
- Shore fishing. 33 ft of water just 1,000 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. 33 ft deep 1,000 ft from shore; 66 ft is far out (1.2 mi): for deeper dives, go by boat.
