Tides

Tides in Oshamambe

Today's high and low tides

  • ▲ High tide 3:42 am 1.1 ft
  • ▼ Low tide 11:14 am 0.3 ft
  • ▼ Low tide 10:44 pm 0.8 ft

↑ Rising The tide is rising. 4 h 8 min to high tide at 6:40 pm.

In Oshamambe the astronomical tide is very small: about 0.8 ft between high and low tide. Here the sea level is moved mostly by wind and air pressure (storm surge), which can raise or lower it more than the tide itself.

2026 extremes: the highest tide of the year is on August 13 (1.3 ft) and the lowest, on March 22 (-0.4 ft).

Heights above chart datum (CD), the zero of that port's nautical charts. 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 (CD)

Where this tide comes from

No significant tide

Tides from the Suttsu station (JMA), 21 mi from Oshamambe. Times and heights are its predictions.

How we calculate the tide

Sea and waves

The sea at Oshamambe

7-day waves

Sea stateSea state: smooth

Smooth Douglas 2 · fresh breeze, Beaufort 5
Waves 1.0 ft · 4.7 s from the south (172°)
Swell 0.5 ft · 9.1 s from the southeast
Current 0.4 mph toward the NNE

The waves you may find

  • Most commonMost common0.5 ft
  • Significant1.0 ft
  • Highest expectedHighest2.1 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 2.1 ft. Before heading out, expect waves of up to 2.1 ft.

Wind on the coast and offshore

On the coast 9 mph SSW · gusts 24
Offshore (6.3 mi E)Offshore 19 mph SSW · gusts 27

Cross-onshore wind. The coast faces southeast 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 build over the next few days. The biggest waves arrive on Sunday 1: 2.5 ft with a period of 4 s, from the west (slight).

Water temperature

Water now56.3 °F

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 53.8 °F by Wednesday 4.

Water about normal for late October.

Your diving day at a glance

The best window, 8:20 am to 11:20 am, combines little swell, light wind, weak current and the sun high.

In Oshamambe the tide barely moves the water, so there's no slack to wait for: swell, wind and current are what count.

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
  • 12:39–2:39 am Major · the moon passes overhead · high activity
  • 1:11–3:11 pm Major · the moon passes underfoot · high activity
  • 9:22–10:22 am Minor · moonset · medium activity
  • 5:58–6:58 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.
