- ▼ Low tide 8:31 am 1.2 ft
- ▲ High tide 2:13 pm 2.4 ft · coef. 82

↑ Rising The tide is rising. 44 min to high tide at 2:41 am.
Tide coefficient 89 for the 2:41 am high tide and 82 for the 2:13 pm high tide. Average coefficient. The water rises and falls 1.9 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 March 20 (3.0 ft) and the lowest, on July 14 (0.0 ft).
Mixed: two high and two low tides a day, but of quite different heights.
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 came from October 25 to 27 (coefficient 107, 2.3 ft range). The smallest, from October 18 to 19 (coefficient 20, 0.0 ft).

Where this tide comes from
Grand Baie has no station of its own, so we use the tide at Port Louis (TICON-4), 11 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 Grand Baie
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.5 ft
- Significant3.0 ft
- Highest expectedHighest6.0 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 6.0 ft. Before heading out, expect waves of up to 6.0 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 northwest 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 Sunday 1: 4.6 ft with a period of 7 s, from the east-northeast (moderate).
Water temperature
Water temperature →Water temperature changes how fish behave: in very cold or very warm water they feed less. The water warms over the next few days: about 78.4 °F by Wednesday 4.

Surf in Grand Baie today
Surf today
Poor- 0.9–1.4 ft surf at the shore, small: good for learning or a longboard
- 2.3 ft swell at 5 s from the east-northeast, short: weak, messy waves; it hits this coast at an angle
- 1.4 ft wind swell at 3 s: messy waves
- Moderate cross-shore wind (14 mph): a bit of chop
- Falling tide (low tide at 8:31 am)
- Light: First light 5:07 am · sunrise 5:30 am · sunset 6:17 pm · last light 6:40 pm
- Tide: high 2:41 am (2.2 ft), low 8:31 am (1.2 ft), high 2:13 pm (2.4 ft) and low 9:04 pm (0.5 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 77.0 °F–77.9 °F: boardshorts or a swimsuit and a rash guard.
- Energy: 26 kJ · Low power
Today’s surf at a glance
The best window is 5:07 am to 9:00 am, though with small waves, a short-period swell, wind 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 Grand Baie today
Diving and snorkeling today
Likely visibility: good- Slack water around high tide (2:13 pm): little current from 1:50 pm to 2:30 pm
- 2.0 ft swell at 5 s from the east-northeast: some surge on the bottom
- Light cross-shore wind (12 mph)
- 0.2 mph current toward the southwest, weak (model)
- Sun high: more light underwater
- Slack water today: high tide 2:41 am (2:20–3:00 am), low tide 8:31 am (7:50–9:00 am), high tide 2:13 pm (1:50–2:30 pm) and low tide 9:04 pm (8:40–9:30 pm)
- Likely visibility: good. Swell (up to 2.6 ft at 5 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 77.0–77.9 °F: a 3 mm wetsuit.
- Snorkeling: doable, with some waves or wind.
- Night dive: dark from 6:40 pm. Waning gibbous (86%), rising at 10:00 pm: a bright night.
Your diving day at a glance
The best window, 1:20 pm to 2:40 pm, combines slack water at high tide, light wind, weak current and the sun high. Also worth a look from 7:10 am to 9:40 am, with slack water at low tide and weak current, 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 226,557 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 1:25–3:25 am Major · the moon passes overhead · high activity
- 1:57–3:57 pm Major · the moon passes underfoot · high activity
- 7:24–8:24 am Minor · moonset · medium activity
- 9:30–10:30 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.

- 33 ft deep2.7 mi
- 66 ft deep2.8 mi
- 164 ft deep3 mi
For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 2.7 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 2.7 mi. For dives deeper than 33 ft, go by boat.
Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves). The profile is turned slightly from the coast so it does not run into an island or a headland. Where the bottom comes up to the surface there are shoals, rocks or an islet next to the profile.
