Fishing barometer

1013 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 1010 hPa max 1014 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.

UV index

solar protection

UV 9

Very high

Very high exposure — unprotected skin burns quickly. Cover up, reapply sunscreen often and keep out of the midday sun.

1–2 · Low
Little risk — most people need no sun protection.
3–7 · Moderate to high
Wear a hat, sunglasses and SPF 30+, and take shade around midday.
8+ · Very high to extreme
Use SPF 50+, cover up and stay out of the sun through the middle of the day.

The sea surface holds around 29.1° today, moving between 29.0° and 29.3°. Water temperature sets the pace of fish metabolism, so even a small shift can change where fish hold and how actively they feed.

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.

These figures describe the swell out in open water. Closer to the beach the waves shift with the shape of the coastline and the seabed, though in most spots they end up broadly similar.

Major periods track the moon's transit and opposing transit and run about two hours; minor periods open at moonrise and moonset and last about an hour. When a period lands on sunrise or sunset, activity climbs higher still — and that overlap happens today.

Bite windows

Friday 4 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

05:30 – 07:30

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

High tide turn

12:10 – 14:10

Water peaks at 13:10 then starts to fall.

Prime window

17:00 – 19:00

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

Frequently asked questions

Tides, coefficients and fishing times for Colonia, explained.

What time is high tide in Colonia today?

High water at Colonia today is at 13:10. 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?

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 33 (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 today?

The sun rises at 06:38 and sets at 18:54 local time, giving 12h 16m of daylight.

What is the water temperature in Colonia today?

The sea surface at Colonia is around 29.1°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 today?

The significant wave height at Colonia is currently 1.4 m with a period of 6.1 s between crests. Individual sets can stack up to roughly twice that height, so allow a margin at exposed marks and anchorages.
