Where this tide comes from
Stene has no station of its own, so we use the tide at Cadzand (TICON-4), 23 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 Stene
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.1 ft
- Significant2.3 ft
- Highest expectedHighest4.8 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 4.8 ft. Before heading out, expect waves of up to 4.8 ft.
Wind on the coast and offshore
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 Monday 2: 5.0 ft with a period of 5 s, from the north-northeast (moderate).
Water temperature
Water temperature →The satellite measured 2.9 °F more yesterday than the model gives now: the water is probably warmer than the forecast says.
Water temperature changes how fish behave: in very cold or very warm water they feed less. The water cools over the next few days: about 55.1 °F by Tuesday 3.
Water warmer than normal for late October (+1.3 °F).

Surf in Stene today
Surf today
Poor- 1.3–2.0 ft surf at the shore, a fun size for most surfers
- 1.4 ft swell at 4 s from the west-northwest, short: weak, messy waves
- 1.6 ft wind swell at 3 s: messy waves
- Light offshore wind (6 mph): it holds up and grooms the waves
- First or last light of the day
- Falling tide (low tide at 8:52 am)
- Light: First light 6:59 am · sunrise 7:34 am · sunset 5:30 pm · last light 6:04 pm
- Tide: high 2:49 am (16.4 ft), low 8:52 am (2.3 ft), high 3:08 pm (16.6 ft) and low 9:13 pm (2.0 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 55.9 °F: a 5/4 fullsuit with booties (and a hood if it’s windy).
- Energy: 9 kJ · Low power
Today’s surf at a glance
The best window, 7:00 am to 10:00 am, has light offshore wind, though with a short-period swell and wind swell. 11:00 am to 3:00 pm can also work, though with a short-period swell and wind 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.

Diving in Stene today
Diving and snorkeling today
Likely visibility: good- Slack water around high tide (3:08 pm): little current from 2:53 pm to 3:23 pm
- 2.8 ft surface waves
- Light onshore wind (9 mph)
- 0.1 mph current toward the west, weak (model)
- Sun high: more light underwater
- Slack water today: high tide 2:49 am (2:34–3:04 am), low tide 8:52 am (8:30–9:10 am), high tide 3:08 pm (2:53–3:23 pm) and low tide 9:13 pm (8:50–9:30 pm)
- Likely visibility: good. Swell (up to 2.5 ft at 5 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 55.9 °F: a 7 mm semi-dry suit, with hood, gloves and booties.
- Snorkeling: doable, with some waves or wind.
- Night dive: dark from 6:04 pm. Waning gibbous (93%), rising at 6:16 pm: a bright night.
Your diving day at a glance
The best window, 2:40 pm to 3:30 pm, combines slack water at high tide, light wind, weak current and the sun high. Also good from 8:20 am to 9:50 am, with slack water at low tide, light wind and weak 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 226,461 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 1:10–3:10 am Major · the moon passes overhead · high activity
- 1:41–3:41 pm Major · the moon passes underfoot · high activity
- 10:31–11:31 am Minor · moonset · medium activity
- 5:46–6:46 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 0.3 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 2.8 mi. For dives deeper than 33 ft, go by boat.
