↑ Rising The tide is rising. 6 h 18 min to high tide at 10:18 am.
Tide coefficient 96 for the 10:18 am high tide and 91 for the 10:42 pm high tide. Spring tides. The water rises and falls 4.0 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 December 26 (5.2 ft) and the lowest, on May 18 (0.0 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

Surf in Glenridge Crescent today
Surf today
Good- 3.0–4.5 ft surf at the shore, a good size with some punch
- 4.7 ft swell at 9 s from the north, a bit short
- Moderate offshore wind (14 mph): it holds up and grooms the waves
- First or last light of the day
- Rising tide (high tide at 10:18 am)
- Light: First light 7:08 am · sunrise 7:40 am · sunset 5:48 pm · last light 6:20 pm
- Tide: low 3:49 am (1.0 ft), high 10:18 am (4.8 ft), low 4:54 pm (0.8 ft) and high 10:42 pm (3.6 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 45.0 °F: a 6/5 hooded fullsuit with booties and gloves.
- Energy: 351 kJ · Medium power
Today’s surf at a glance
The best window, 7:08 am to 11:00 am, has 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 Glenridge Crescent today
Diving and snorkeling today
Likely visibility: poor- Slack water around high tide (10:18 am): little current from 10:00 am to 10:40 am
- 4.4 ft swell at 9 s from the north: strong surge on the bottom
- Moderate offshore wind (13 mph): it pushes surface swimmers away from shore
- 0.5 mph current toward the south-southeast, weak (model)
- Sun high: more light underwater
- Slack water today: low tide 3:49 am (3:20–4:20 am), high tide 10:18 am (10:00–10:40 am), low tide 4:54 pm (4:30–5:10 pm) and high tide 10:42 pm (10:10–11:10 pm)
- Likely visibility: poor. Swell (up to 6.2 ft at 9 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 45.0 °F: a drysuit, with hood, gloves and booties.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 6:20 pm. Waning gibbous (84%), rising at 7:59 pm: a bright night.
Your diving day at a glance
The best window, 9:40 am to 11:10 am, combines slack water at high tide, weak current and the sun high, though with some swell and moderate wind. Also worth a look from 3:20 pm to 5:50 pm, with slack water at low tide, though with some swell, moderate 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.
