Where this tide comes from
Tides from the St Marys station (Environment Agency), 3.3 mi from Higher Town. Times and heights are its predictions.

The sea at Higher Town
Sea stateSea state: moderate
The waves you may find
- Most commonMost common3.6 ft
- Significant7.3 ft
- Highest expectedHighest15 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 15 ft. Before heading out, expect waves of up to 15 ft.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
Cross-offshore wind. The coast faces northeast 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 ease over the next few days. The biggest waves arrive on Wednesday 28: 12 ft with a period of 11 s, from the west (rough).

Surf in Higher Town today
Surf today
Good- 2.0–3.1 ft surf at the shore, a fun size for most surfers
- 10 ft swell at 10 s from the west-southwest, average; this coast faces away from it
- Fresh offshore wind (20 mph): it holds up and grooms the waves
- Falling tide (low tide at 12:05 pm)
- Light: First light 6:34 am · sunrise 7:08 am · sunset 5:09 pm · last light 5:43 pm
- Tide: high 5:36 am (18.6 ft), low 12:05 pm (2.1 ft) and high 5:57 pm (18.4 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 56.5 °F: a 5/4 fullsuit with booties (and a hood if it’s windy).
- Energy: 1,927 kJ · Very high power
Today’s surf at a glance
The best window, 7:00 am to 8:00 am, has a good size and light offshore wind. 9:00 am to 1:00 pm also works, with a good size and light offshore 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 Higher Town today
Diving and snorkeling today
Likely visibility: poor- Tidal current running: mid-tide, the water is moving
- 10 ft swell at 10 s from the west-southwest: heavy surge on the bottom
- Fresh offshore wind (19 mph): it pushes surface swimmers away from shore
- 1.7 mph current toward the southwest, strong (model)
- Daylight
Not a day for shore diving: swell, wind, current or storms during the best window. If you go, go with a dive shop and only if they give the OK.
- Slack water today: high tide 5:36 am (5:20–5:51 am), low tide 12:05 pm (11:40 am–12:20 pm) and high tide 5:57 pm (5:40–6:12 pm)
- Likely visibility: poor. Swell (up to 12 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 56.5 °F: a 7 mm semi-dry suit, with hood, gloves and booties.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 5:43 pm. Waning gibbous (92%), rising at 6:02 pm: a bright night.
Your diving day at a glance
The best window runs from 6:30 am to 9:30 am, though with tidal current, a big swell, fresh wind and 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.

Moon phase and position
Today the moon is 226,451 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 12:48–2:48 am Major · the moon passes overhead · high activity
- 1:19–3:19 pm Major · the moon passes underfoot · high activity
- 10:02–11:02 am Minor · moonset · medium activity
- 5:32–6:32 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 0.35 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. Shore diving works here: 33 ft at 0.45 mi and 66 ft at 0.6 mi from shore.
