Where this tide comes from
Folkestone has no station of its own, so we use the tide at Dover (Environment Agency), 7.1 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): Dover (E71624), https://environment.data.gov.uk/flood-monitoring/id/stations/E71624. 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 (269 days; without 2026-05-28 to 2026-08-25, when the gauge was faulty).
The sea at Folkestone
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.7 ft
- Significant1.4 ft
- Highest expectedHighest3.0 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 3.0 ft. Before heading out, expect waves of up to 3.0 ft.
Wind on the coast and offshore
Cross-offshore wind. The coast faces southeast and the wind comes off the land at an angle: calmer water near the shore, and bait and boats drift out to sea.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Monday 2: 3.0 ft with a period of 4 s, from the northeast (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.

Surf in Folkestone today
Surf today
Poor- 1.0–1.4 ft surf at the shore, small: good for learning or a longboard
- 1.4 ft swell at 5 s from the southwest, short: weak, messy waves
- Light offshore wind (8 mph): it holds up and grooms the waves
- First or last light of the day
- Falling tide (high tide at 11:50 am)
- Light: First light 6:06 am · sunrise 6:41 am · sunset 4:37 pm · last light 5:11 pm
- Tide: low 7:12 am (3.0 ft), high 11:50 am (22.6 ft) and low 7:36 pm (2.7 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.
- Water at 59.4 °F: a 4/3 fullsuit (booties if you run cold).
- Energy: 8 kJ · Low power
Today’s surf at a glance
The best window, 6:06 am to 10:00 am, has light offshore wind, though with small waves and a short-period swell.
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 Folkestone today
Diving and snorkeling today
Likely visibility: good- Slack water around high tide (11:50 am): little current from 11:35 am to 12:30 pm
- 1.2 ft swell at 5 s from the southwest: barely any surge
- Moderate cross-shore wind (13 mph)
- 1.0 mph current toward the northeast (model)
- Sun high: more light underwater

- Likely visibility: good. Swell (up to 3.4 ft at 5 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 59.4 °F: a 7 mm wetsuit, with hood and booties.
- Snorkeling: doable, with some waves or wind.
- Night dive: dark from 5:11 pm. Waning gibbous (92%), rising at 5:24 pm: a bright night.
Your diving day at a glance
The best window, 11:20 am to 2:10 pm, combines slack water at high tide, little swell and the sun high, though with moderate wind and current. Also worth a look from 3:50 pm to 4:30 pm, with little swell, light wind and weak current, though with tidal 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.

Moon phase and position
Today the moon is 226,451 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 12:17–2:17 am Major · the moon passes overhead · high activity
- 12:48–2:48 pm Major · the moon passes underfoot · high activity
- 9:37–10:37 am Minor · moonset · medium activity
- 4:54–5:54 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.
