Today's high and low tides
- ▼ Next low tide 2:44 am 0.2 ft
- ▲ High tide 8:29 am 0.3 ft
- ▼ Low tide 4:01 pm 0.1 ft
↓ Falling The tide is falling. 54 min to low tide at 2:44 am.
In Ruhnu the astronomical tide is very small: about 0.2 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 December 25 (0.6 ft) and the lowest, on April 26 (-0.6 ft).
Heights above mean sea level. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. mean sea level

The waves you may find
- Most commonMost common1.0 ft
- Significant1.9 ft
- Highest expectedHighest4.1 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 4.1 ft. Before heading out, expect waves of up to 4.1 ft.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
Offshore wind. The coast faces northeast and the wind blows from land out to sea: calm shore and clean waves, but watch the drift out to sea.

Waves build over the next few days. The biggest waves arrive on Tuesday 3: 5.8 ft with a period of 5 s, from the north (moderate).

Moon phase and position
Today the moon is 226,597 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
- 2:20–4:20 pm Major · the moon passes underfoot · high activity
- 12:28–1:28 pm Minor · moonset · medium activity
- 5:12–6:12 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 0.3 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 1.2 mi. For dives deeper than 33 ft, go by boat.
