2026 extremes: the highest tide of the year is on December 26 (20.4 ft) and the lowest, on August 14 (0.7 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 93, 16.4 ft range). The smallest, from October 19 to 20 (coefficient 37, 7.2 ft).

Where this tide comes from
Y Felinheli has no station of its own, so we use the tide at Holyhead (Environment Agency), 19 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): Holyhead (E70524), https://environment.data.gov.uk/flood-monitoring/id/stations/E70524. 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 (356 days).

Sea stateSea state: slight
The waves you may find
- Most commonMost common1.0 ft
- Significant2.0 ft
- Highest expectedHighest4.2 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 4.2 ft. Before heading out, expect waves of up to 4.2 ft.
Wind on the coast and offshore
Cross-shore wind. The coast faces west and the wind blows along the shore: drift and current run parallel to the beach.
Wave height, next 7 daysWaves, next 7 days
Waves stay much the same all week. The biggest waves arrive on Friday 30: 2.2 ft with a period of 5 s, from the southwest (slight).
Water temperature

- Likely visibility: fair. Swell (up to 2.7 ft at 7 s) and rain (0.22 in) over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 54.3 °F: a 7 mm semi-dry suit, with hood, gloves and booties.
- Snorkeling: doable, with some waves or wind.
- Night dive: dark from 5:27 pm. Waning gibbous (85%), rising at 6:26 pm: a bright night.
Your diving day at a glance
The best window, 10:40 am to 1:00 pm, combines slack water at high tide, little swell, light wind, weak current and the sun high.
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.

Moon phase and position
Today the moon is 226,641 mi away and looks 32′ 45″ across.
Solunar periods
Today's activity: medium- 1:43–3:43 am Major · the moon passes overhead · high activity
- 2:15–4:15 pm Major · the moon passes underfoot · high activity
- 11:34 am–12:34 pm Minor · moonset · medium activity
- 5:56–6:56 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.

- 66 ft deepnot within 0.3 mi
- 164 ft deepnot within 0.3 mi
For fishing, swimming and diving
- Shore fishing. About 7.2 ft of water 330 ft out: long casts help, and so does a rising tide, which brings fish closer in.
- Swimming. The water gets deeper little by little, but a few dozen yards out you can no longer stand.
- Diving. Shallow: the water doesn't reach 33 ft within 0.3 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. There is land ahead (an island, a headland or the far shore) 0.3 mi out. Where the bottom comes up to the surface there are shoals, rocks or an islet next to the profile.
