The sea at Stuifakker
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.7 ft
- Significant1.4 ft
- Highest expectedHighest3.1 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 3.1 ft. Before heading out, expect waves of up to 3.1 ft.
Wind on the coast and offshore
Cross-onshore wind. The coast faces west and the wind comes in from the sea at an angle: a bit more surf at the shore and drift along the coast, toward land.
Wave height, next 7 daysWaves, next 7 days
Waves stay much the same all week. The biggest waves arrive on Monday 2: 2.2 ft with a period of 5 s, from the north (slight).
Water temperature
Water temperature →The satellite measured 2.7 °F more 2 days ago 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 is steady these days, with no sudden changes.
Water colder than normal for late October (−1.0 °F).

Today’s surf at a glance
The best window, 2:00 pm to 5:57 pm, has glassy water, though with barely any waves.
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.

Your diving day at a glance
The best window, 11:30 am to 1:50 pm, combines little swell, light wind, weak current and the sun high. Also worth a look from 9:30 am to 10:10 am, with slack water at low tide, little swell, light wind and the sun high, though with 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.

Moon phase and position
Today the moon is 226,618 mi away and looks 32′ 45″ across.
Solunar periods
Today's activity: medium- 2:08–4:08 am Major · the moon passes overhead · high activity
- 2:41–4:41 pm Major · the moon passes underfoot · high activity
- 11:49 am–12:49 pm Minor · moonset · medium activity
- 6:32–7:32 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 2.8 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: the water doesn't reach 33 ft within 3.1 mi. For deeper dives, take a boat farther out.
The profile is turned slightly from the coast so it does not run into an island or a headland.
