↑ Rising The tide is rising. 4 h 31 min to high tide at 10:22 pm.
Tide coefficient 99 for the 12:04 pm high tide and 97 for the 10:22 pm high tide. Spring tides. The water rises and falls 2.9 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.

2026 extremes: the highest tide of the year is on December 25 (3.6 ft) and the lowest, on May 18 (-0.1 ft).
Mixed: two high and two low tides a day, but of quite different heights.
Heights above lower low water, large tide (LLWLT), the zero of Canadian charts. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. LLWLT

The waves you may find
- Most commonMost common1.9 ft
- Significant3.9 ft
- Highest expectedHighest8.1 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 8.1 ft. Before heading out, expect waves of up to 8.1 ft.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
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.

Waves ease over the next few days. The biggest waves arrive on Wednesday 28: 6.7 ft with a period of 7 s, from the northwest (moderate).

Surf in Cap-aux-Meules today
Surf today
Poor- 1.5–2.4 ft surf at the shore, a fun size for most surfers
- 3.7 ft swell at 7 s from the north-northwest, short: weak, messy waves; it hits this coast at an angle
- 3.2 ft wind swell at 5 s: messy waves
- Fresh offshore wind (23 mph)
- Rising tide (high tide at 12:04 pm)
- Light: First light 7:13 am · sunrise 7:45 am · sunset 5:57 pm · last light 6:28 pm
- Tide: low 4:27 am (0.4 ft), high 12:04 pm (3.2 ft), low 4:45 pm (2.0 ft) and high 10:22 pm (3.3 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.

- Energy: 162 kJ · Medium power
Today’s surf at a glance
The best window is 8:00 am to 12:00 pm, though with a short-period swell and wind swell. 3:00 pm to 6:00 pm can also work, though with small waves and a short-period swell.
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 Cap-aux-Meules today
Diving and snorkeling today
Likely visibility: fair- Slack water around high tide (12:04 pm): little current from 11:10 am to 12:40 pm
- 3.4 ft swell at 6 s from the north-northwest: some surge on the bottom
- Fresh offshore wind (19 mph): it pushes surface swimmers away from shore
- 0.4 mph current toward the east-southeast, weak (model)
- Sun high: more light underwater
- Slack water today: low tide 4:27 am (4:10–4:42 am), high tide 12:04 pm (11:10 am–12:40 pm), low tide 4:45 pm (4:30–5:10 pm) and high tide 10:22 pm (10:07–10:37 pm)
- Likely visibility: fair. Swell (up to 3.7 ft at 7 s) and wind over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 46.6 °F: a drysuit, with hood, gloves and booties.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 6:28 pm. Waning gibbous (92%), rising at 7:07 pm: a bright night.
Your diving day at a glance
The best window, 11:10 am to 1:20 pm, combines slack water at high tide, weak current and the sun high, though with some swell and fresh 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.
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 226,432 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 1:40–3:40 am Major · the moon passes overhead · high activity
- 2:12–4:12 pm Major · the moon passes underfoot · high activity
- 10:42–11:42 am Minor · moonset · medium activity
- 6:37–7:37 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. Very shallow: the water doesn't reach 16 ft within 3.1 mi. Cast far from the beach, ideally around high tide.
- 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: the water doesn't reach 33 ft within 3.1 mi. For deeper dives, take a boat farther out.
