Tides in Östhammar
Today's high and low tides
- ▲ High tide 4:34 am 0.2 ft
- ▼ Low tide 9:09 pm 0.1 ft
↑ Rising The tide is rising. 6 h 34 min to high tide at 5:24 am.
In Östhammar the astronomical tide is very small: about 0.1 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 (0.5 ft) and the lowest, on April 27 (-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

Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.3 ft
- Significant0.7 ft
- Highest expectedHighest1.4 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 1.4 ft. Before heading out, expect waves of up to 1.4 ft.
Wind on the coast and offshore
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.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Tuesday 3: 2.8 ft with a period of 4 s, from the north-northwest (slight).
Water temperature

Moon phase and position
Today the moon is 226,461 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 12:05–2:05 am Major · the moon passes overhead · high activity
- 12:36–2:36 pm Major · the moon passes underfoot · high activity
- 10:55–11:55 am Minor · moonset · medium activity
- 3:10–4:10 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 1,050 ft): 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: the water doesn't reach 33 ft within 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. There is land ahead (an island, a headland or the far shore) 1 mi out. The profile is turned slightly from the coast so it does not run into an island or a headland.
