The sea at Hellschen-Heringsand-Unterschaar
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.5 ft
- Significant3.0 ft
- Highest expectedHighest6.1 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 6.1 ft. Before heading out, expect waves of up to 6.1 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 Thursday 29: 4.0 ft with a period of 5 s, from the west-southwest (slight).
Water temperature

Surf in Hellschen-Heringsand-Unterschaar today
Surf today
Poor- 1.8–2.8 ft surf at the shore, a fun size for most surfers
- 2.7 ft swell at 5 s from the west, short: weak, messy waves
- Almost no wind (2 mph): glassy water
- Falling tide (low tide at 9:56 am)
- Light: First light 6:42 am · sunrise 7:20 am · sunset 4:56 pm · last light 5:33 pm
- Tide: high 3:30 am (9.1 ft), low 9:56 am (1.8 ft), high 3:59 pm (9.1 ft) and low 10:16 pm (2.2 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 53.4 °F–54.3 °F: a 5/4 fullsuit with booties (and a hood if it’s windy).
- Energy: 27 kJ · Low power
Today’s surf at a glance
The best window, 7:00 am to 11:00 am, has a good size and glassy water, though with a short-period swell. 4:00 pm to 5:33 pm can also work, with glassy water, though with 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.

- Snorkeling: doable, with some waves or wind.
- Night dive: dark from 5:33 pm. Waning gibbous (85%), rising at 6:22 pm: a bright night.
Your diving day at a glance
The best window, 1:50 pm to 4:50 pm, combines slack water at high tide, light wind and weak current. Also worth a look from 9:10 am to 10:20 am, with slack water at low tide, 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: high- 1:48–3:48 am Major · the moon passes overhead · high activity
- 2:21–4:21 pm Major · the moon passes underfoot · high activity
- 11:48 am–12:48 pm Minor · moonset · medium activity
- 5:52–6:52 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.
