Fishing barometer

1016 hPa ↗ Rising
  • Rising Very good — today Rising pressure after a low signals settling weather — fish feed confidently and this is often the best barometer window of all.
  • Stable Normal activity A steady barometer for a day or more means settled conditions and predictable, average feeding around tides and solunar peaks.
  • Falling Good at first A dropping barometer sparks a burst of feeding before the weather turns, then activity slows markedly as the front arrives.
min 1009 hPa max 1016 hPa Hover, tap or arrow-key the line to read any hour.

The barometer is rising, which usually switches feeding back on: fish sense settling conditions and move to feed with confidence. A rising trend after a spell of low pressure is one of the strongest signals to get out on the water.

Little risk — most people need no sun protection.

Very high High Average Low

A larger coefficient means a wider gap between high and low water, so the strongest currents run along the sea bed. Tidal range also shifts with the weather — check the wind and swell before you head out.

Swell

Bite windows

Thursday 3 September

Fish feed hardest when the water starts moving — plan around the hour before and after each tide turn, and doubly so where a turn meets a solunar major period.

Prime window

03:50 – 05:50

Tide turn overlaps a major solunar period — the best bite of the day.

High tide turn

11:00 – 13:00

Water peaks at 12:00 then starts to fall.

Prime window

16:50 – 18:50

Tide turn overlaps a major solunar period — the best bite of the day.

High tide turn

21:50 – 23:50

Water peaks at 22:50 then starts to fall.

Frequently asked questions

Tides, coefficients and fishing times for Colonia del Sacramento, explained.

What time is high tide in Colonia del Sacramento today?

High water at Colonia del Sacramento today is at 12:00 and 22:50. The full list of high and low tide times is in the table above and refreshes every day.

Is today a good day to fish in Colonia del Sacramento?

Based on solunar theory the fishing rating today is Slow. The strongest windows are the major periods around the lunar transit, which often line up with sunrise and sunset.

What is the tidal coefficient and why does it matter?

The coefficient runs from 0 to 120 and measures the tidal range — today it is 41 (Low). Higher numbers mean stronger currents and a bigger gap between high and low water, which matters for fishing, diving and boating.

When are sunrise and sunset in Colonia del Sacramento today?

The sun rises at 07:07 and sets at 18:34 local time, giving 11h 27m of daylight.

What is the water temperature in Colonia del Sacramento today?

The sea surface at Colonia del Sacramento is around 13.5°C right now. Water temperature sets the pace of fish metabolism, so the hourly strip above is worth a glance — even a small shift can change where fish hold and how actively they feed.

How big are the waves in Colonia del Sacramento today?

The significant wave height at Colonia del Sacramento is currently 0.4 m with a period of 2.8 s between crests. Individual sets can stack up to roughly twice that height, so allow a margin at exposed marks and anchorages.
