↓ Falling The tide is falling. 5 h 16 min to low tide at 3:13 am.
Tide coefficient 111 for the 10:47 am high tide. Big spring tides. The water rises and falls 1.2 ft between the highest high and the lowest low: a large range for this place. 70 is an average tide here; 90 and above means spring tides; below 45, neap tides. What is the tide coefficient?
2026 extremes: the highest tide of the year is on October 27 (1.8 ft) and the lowest, on May 18 (0.0 ft).
Mixed, mainly diurnal: on many days there is only one high and one low tide.
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 come from October 28 to 29 (coefficient 113, 1.3 ft range). The smallest, on October 8 (coefficient 20, 0.2 ft).

Where this tide comes from
Island Harbour has no station of its own, so we use the tide at Saint-Martin (TICON-4), 13 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.

The sea at Island Harbour
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.7 ft
- Significant3.5 ft
- Highest expectedHighest7.1 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 7.1 ft. Before heading out, expect waves of up to 7.1 ft.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
Cross-shore wind. The coast faces north 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 Tuesday 3: 3.9 ft with a period of 6 s, from the east (slight).
Water temperature

Surf in Island Harbour today
Surf today
Poor- 2.0–3.1 ft surf at the shore, a fun size for most surfers
- 2.5 ft swell at 7 s from the north, short: weak, messy waves
- Moderate cross-shore wind (14 mph): a bit of chop
- Falling tide
- Light: First light 5:48 am · sunrise 6:10 am · sunset 5:41 pm · last light 6:04 pm
- Tide: low 2:39 am (0.6 ft) and high 10:47 am (1.8 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 85.3 °F: boardshorts or a swimsuit and a rash guard.
- Energy: 64 kJ · Low power
Today’s surf at a glance
The best window, 11:00 am to 3:00 pm, has a good size, though with a short-period swell and 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 Island Harbour today
Diving and snorkeling today
Likely visibility: good- Slack water around high tide (10:47 am): little current from 10:32 am to 11:02 am
- 2.5 ft swell at 7 s from the north: some surge on the bottom
- Moderate cross-shore wind (14 mph)
- 0.5 mph current toward the west-northwest, weak (model)
- Sun high: more light underwater
- Slack water today: low tide 2:39 am (2:20–2:54 am) and high tide 10:47 am (10:32–11:02 am)
- Likely visibility: good. Swell (up to 2.9 ft at 9 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 85.3 °F: a shorty or a rash guard.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 6:04 pm. Waning gibbous (91%), rising at 7:52 pm: a bright night.
Your diving day at a glance
The best window, 10:20 am to 11:20 am, combines slack water at high tide, weak current and the sun high, though with moderate wind. Also worth a look from 5:00 pm to 5:40 pm, with 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.
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 226,429 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 12:45–2:45 am Major · the moon passes overhead · high activity
- 1:16–3:16 pm Major · the moon passes underfoot · high activity
- 8:09–9:09 am Minor · moonset · medium activity
- 7:22–8:22 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.

Water depth
Gentle slopeThe bottom slopes gently: 16 ft deep 1,200 ft from shore and 33 ft at 0.35 mi. Right off the beach it already drops to about 14 ft.

- 66 ft deep1.1 mi
- 164 ft deepnot within 3.1 mi
For fishing, swimming and diving
- Shore fishing. Deep water close in: about 14 ft just 330 ft out. Good for casting from rocks, jetties or the beach itself; current and surf hit harder here.
- Swimming. The bottom drops quickly near the shore and you are soon out of your depth. Keep an eye on kids and weak swimmers.
- Diving. 33 ft deep 0.35 mi from shore; 66 ft is far out (1.1 mi): for deeper dives, go by boat.
