Sea stateSea state: moderate
The waves you may find
- Most commonMost common2.1 ft
- Significant4.2 ft
- Highest expectedHighest8.5 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 8.5 ft. Before heading out, expect waves of up to 8.5 ft.
Wind on the coast and offshore
Cross-shore wind. The coast faces northwest and the wind blows along the shore: drift and current run parallel to the beach.
Wave height, next 7 daysWaves, next 7 days
Waves ease over the next few days. The biggest waves arrive on Wednesday 28: 7.2 ft with a period of 9 s, from the west (moderate).

Surf in Combe Martin today
Surf today
Fair- 3.7–5.7 ft surf at the shore, a good size with some punch
- 4.4 ft swell at 9 s from the west-southwest, a bit short
- 3.8 ft wind swell at 4 s: messy waves
- Moderate cross-shore wind (13 mph): a bit of chop
- Falling tide (low tide at 12:55 pm)
- Light: First light 6:27 am · sunrise 7:02 am · sunset 4:57 pm · last light 5:32 pm
- Tide: low 12:35 am (2.9 ft), high 6:54 am (31.5 ft), low 12:55 pm (3.1 ft) and high 7:18 pm (31.3 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 58.8 °F: a 4/3 fullsuit (booties if you run cold).
- Energy: 326 kJ · Medium power
Today’s surf at a glance
The best window, 9:00 am to 10:00 am, has a good size, though with wind swell and cross-shore wind. 2:00 pm to 5:32 pm can also work, with a good size, though with cross-shore 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.
Diving in Combe Martin today
Diving and snorkeling today
Likely visibility: poor- Slack water around low tide (12:55 pm): little current from 12:30 pm to 1:20 pm
- 4.3 ft swell at 8 s from the west: strong surge on the bottom
- Moderate onshore wind (17 mph)
- 0.2 mph current toward the northwest, weak (model)
- Sun high: more light underwater
- Slack water today: low tide 12:35 am (12:10–1:00 am), high tide 6:54 am (6:39–7:10 am), low tide 12:55 pm (12:30–1:20 pm) and high tide 7:18 pm (7:00–7:40 pm)
- Likely visibility: poor. Swell (up to 5.9 ft at 10 s) and wind over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 58.8 °F: a 7 mm wetsuit, with hood and booties.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 5:32 pm. Waning gibbous (92%), rising at 5:45 pm: a bright night.
Your diving day at a glance
The best window, 12:30 pm to 1:30 pm, combines slack water at low tide, weak current and the sun high, though with some swell and moderate wind. Also worth a look from 6:30 am to 7:30 am, with slack water at high tide and weak current, though with some swell, moderate wind and low light.
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- 12:39–2:39 am Major · the moon passes overhead · high activity
- 1:10–3:10 pm Major · the moon passes underfoot · high activity
- 10:00–11:00 am Minor · moonset · medium activity
- 5:15–6:15 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. Shallow, gradual bottom (16 ft at 0.3 mi): cast far from the beach and fish the high tide, when there is more water close in.
- Swimming. A very gentle way in with plenty of shallow water, good for kids. At low tide the water can be far out.
- Diving. 33 ft deep 0.45 mi from shore; 66 ft is far out (1.6 mi): for deeper dives, go by boat.
