Tides in Trosa
Today's high and low tides
- ▼ Low tide 12:01 am 0.0 ft
- ▲ High tide 7:47 am 0.2 ft
↓ Falling The tide is falling. 14 h 43 min to low tide at 12:44 am.
In Trosa 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 (0.4 ft) and the lowest, on April 27 (-0.5 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 sea at Trosa
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.7 ft
- Significant1.3 ft
- Highest expectedHighest2.8 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 2.8 ft. Before heading out, expect waves of up to 2.8 ft.
Wind on the coast and offshore
Cross-onshore wind. The coast faces south 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 stay much the same all week. The biggest waves arrive on Sunday 1: 1.6 ft with a period of 3 s, from the south-southwest (smooth).
Water temperature
Water temperature →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 47.0 °F by Wednesday 4.
Water warmer than normal for late October (+1.8 °F).

The moon in Trosa
Moon phase and position
Today the moon is 226,618 mi away and looks 32′ 45″ across.
Solunar periods
Today's activity: high- 1:12–3:12 am Major · the moon passes overhead · high activity
- 1:44–3:44 pm Major · the moon passes underfoot · high activity
- 12:09–1:09 pm Minor · moonset · medium activity
- 4:19–5:19 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

For fishing, swimming and diving
- Shore fishing. About 6.9 ft of water 330 ft out: long casts help, and so does a rising tide, which brings fish closer in.
- Swimming. The water gets deeper little by little, but a few dozen yards out you can no longer stand.
- Diving. Shallow: the water doesn't reach 33 ft within 1.2 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) 1.2 mi out. Where the bottom comes up to the surface there are shoals, rocks or an islet next to the profile.
