  • ▼ Low tide 10:00 pm 2.2 ft

↑ Rising The tide is rising. 2 h 41 min to high tide at 3:21 am.

Tide coefficient 76 for the 3:21 am high tide and 75 for the 3:49 pm high tide. Average coefficient. The water rises and falls 7.0 ft between the highest high and the lowest low: an average 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 30 (9.7 ft) and the lowest, on April 20 (0.6 ft).

Semidiurnal: two high and two low tides a day, of similar height.

Heights above chart datum: the lowest astronomical tide (LAT), the zero of nautical charts in Europe. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. chart datum (LAT)

Tide coefficient and range in October

The biggest tides of the month came from October 10 to 11 (coefficient 84, 8.4 ft range). The smallest, from October 20 to 21 (coefficient 48, 4.8 ft).

Where this tide comes from

B · Nearby station

Oldsum has no station of its own, so we use the tide at Hörnum (TICON-4), 6.2 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.

How we calculate the tide

Sea and waves

The sea at Oldsum

7-day waves

Sea stateSea state: slight

Slight Douglas 3 · moderate breeze, Beaufort 4
Waves 3.6 ft · 5.4 s from the west (262°)
Swell 2.9 ft · 5.1 s from the west
Current 0.2 mph toward the SSW

The waves you may find

  • Most commonMost common1.8 ft
  • Significant3.6 ft
  • Highest expectedHighest7.4 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 7.4 ft. Before heading out, expect waves of up to 7.4 ft.

Wind on the coast and offshore

On the coast 6 mph W · gusts 10
Offshore (7.9 mi W)Offshore 13 mph W · gusts 17

Cross-onshore wind. The coast faces southwest 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.

Your diving day at a glance

The best window, 9:00 am to 10:20 am, combines slack water at low tide, light wind, weak current and the sun high. Also good from 2:00 pm to 5:00 pm, with slack water at high 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.

Solunar periods

Today's activity: high
  • 1:50–3:50 am Major · the moon passes overhead · high activity
  • 2:22–4:22 pm Major · the moon passes underfoot · high activity
  • 11:55 am–12:55 pm Minor · moonset · medium activity
  • 5:49–6:49 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.

Water depth

Very shallow

Very shallow and flat: even 3.1 mi from shore the water is less than 16 ft deep.

From the shoreline (2.4 mi from Oldsum) out to sea, heading west.

How far from shore

  • 16 ft deepnot within 3.1 mi
  • 33 ft deepnot within 3.1 mi
  • 66 ft deepnot within 3.1 mi
  • 164 ft deepnot within 3.1 mi

For fishing, swimming and diving

  • Shore fishing. Very shallow: the water doesn't reach 16 ft within 3.1 mi. Cast far from the beach, ideally around high tide.
  • 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.

Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide. The profile is turned slightly from the coast so it does not run into an island or a headland.
