Fishing barometer

1015 hPa → Stable
  • Rising Very good Rising pressure after a low signals settling weather — fish feed confidently and this is often the best barometer window of all.
  • Stable Normal activity — today 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 1015 hPa Hover, tap or arrow-key the line to read any hour.

The barometer is holding steady. Expect routine feeding behaviour, with the usual peaks around tide changes and the solunar periods rather than any pressure-driven surge.

Little risk — most people need no sun protection.

The sea surface holds around 10.7° today, moving between 10.7° and 10.8°. 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.

Swell

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.

Frequently asked questions

Tides, coefficients and fishing times for Bahía Rosas, explained.

What time is high tide in Bahía Rosas today?

High water at Bahía Rosas today is at 03:40 and 16:00. 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 Bahía Rosas?

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 Bahía Rosas today?

The sun rises at 07:34 and sets at 18:51 local time, giving 11h 17m of daylight.

What is the water temperature in Bahía Rosas today?

The sea surface at Bahía Rosas is around 10.7°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 Bahía Rosas today?

The significant wave height at Bahía Rosas is currently 1.1 m with a period of 5.2 s between crests. Individual sets can stack up to roughly twice that height, so allow a margin at exposed marks and anchorages.
