The sea at Borkum
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.3 ft
- Significant2.6 ft
- Highest expectedHighest5.5 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 5.5 ft. Before heading out, expect waves of up to 5.5 ft.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
Cross-shore wind. The coast faces north and the wind blows along the shore: drift and current run parallel to the beach.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Monday 2: 5.6 ft with a period of 6 s, from the north-northwest (moderate).
Water temperature
Water temperature →The satellite measured 3.1 °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 about normal for late October.

Surf in Borkum today
Surf today
Poor- 0.9–1.4 ft surf at the shore, small: good for learning or a longboard
- 1.1 ft swell at 5 s from the northwest, short: weak, messy waves
- Light cross-shore wind (5 mph)
- Falling tide (low tide at 6:54 pm)
- Light: First light 6:50 am · sunrise 7:27 am · sunset 5:06 pm · last light 5:43 pm
- Tide: high 12:21 am (9.9 ft), low 6:35 am (1.9 ft), high 12:45 pm (9.8 ft) and low 6:54 pm (2.3 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.
- Water at 53.8 °F: a 5/4 fullsuit with booties (and a hood if it’s windy).
- Energy: 6 kJ · Low power
Today’s surf at a glance
The best window is 2:00 pm to 5:43 pm, 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.

Your diving day at a glance
The best window, 10:50 am to 1:30 pm, combines slack water at high 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.
Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

Solunar periods
Today's activity: medium- 1:57–3:57 am Major · the moon passes overhead · high activity

- 11:52 am–12:52 pm Minor · moonset · 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.

- 66 ft deepnot within 3.1 mi
- 164 ft deepnot within 3.1 mi
For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 2.6 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 3 mi. For dives deeper than 33 ft, go by boat.
