Where this tide comes from
Crail has no station of its own, so we use the tide at Leith (Environment Agency), 28 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): Leith (E70824), https://environment.data.gov.uk/flood-monitoring/id/stations/E70824. Contains public sector information licensed under the Open Government Licence v3.0 (https://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/).

The sea at Crail
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.6 ft
- Significant1.1 ft
- Highest expectedHighest2.3 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 2.3 ft. Before heading out, expect waves of up to 2.3 ft.
Wind on the coast and offshore
Offshore wind. The coast faces east and the wind blows from land out to sea: calm shore and clean waves, but watch the drift out to sea.
Wave height, next 7 daysWaves, next 7 days
Waves ease over the next few days. The biggest waves arrive on Wednesday 28: 2.9 ft with a period of 4 s, from the southwest (slight).
Water temperature

Flat- Barely any waves (0.9 ft sets): flat

- Falling tide (low tide at 9:08 am)
It’s flat today: almost no waves reach this coast.
- Light: First light 6:30 am · sunrise 7:10 am · sunset 4:38 pm · last light 5:17 pm
- Tide: high 3:17 am (19.5 ft), low 9:08 am (2.8 ft), high 3:44 pm (18.8 ft) and low 9:28 pm (2.9 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, 7:00 am to 11:00 am, has light offshore wind, though with barely any waves.
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 Crail today
Diving and snorkeling today
Likely visibility: fair- Slack water around high tide (3:44 pm): little current from 3:10 pm to 4:10 pm
- 0.5 ft swell at 5 s from the southeast: barely any surge
- Moderate offshore wind (13 mph): it pushes surface swimmers away from shore
- 0.3 mph current toward the southeast, weak (model)
- Daylight
- Slack water today: high tide 3:17 am (2:40–3:40 am), low tide 9:08 am (8:40–9:40 am), high tide 3:44 pm (3:10–4:10 pm) and low tide 9:28 pm (9:00–10:00 pm)
- Likely visibility: fair. Swell (up to 3.0 ft at 5 s) and wind over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 53.6 °F: a 7 mm semi-dry suit, with hood, gloves and booties.
- Snorkeling: doable, with some waves or wind.
- Night dive: dark from 5:17 pm. Waning gibbous (92%), rising at 4:57 pm: a bright night.
Your diving day at a glance
The best window, 2:20 pm to 4:30 pm, combines slack water at high tide, little swell and weak current, though with moderate wind. Also worth a look from 8:50 am to 10:20 am, with slack water at low tide, little swell, weak current and the sun high, though with 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.

Moon phase and position
Today the moon is 226,451 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 12:33–2:33 am Major · the moon passes overhead · high activity
- 1:04–3:04 pm Major · the moon passes underfoot · high activity
- 10:35–11:35 am Minor · moonset · medium activity
- 4:27–5:27 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 0.25 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. Shallow near shore: you only reach 33 ft at 0.7 mi. For dives deeper than 33 ft, go by boat.
