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.

Low tide turn

01:40 – 03:40

Water bottoms out at 02:40 then starts to rise.

High tide turn

07:30 – 09:30

Water peaks at 08:30 then starts to fall.

Low tide turn

13:50 – 15:50

Water bottoms out at 14:50 then starts to rise.

Prime window

19:00 – 21:00

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

Frequently asked questions

Tides, coefficients and fishing times for Juan L. Lacaze, explained.

What time is high tide in Juan L. Lacaze today?

High water at Juan L. Lacaze today is at 08:30 and 20:00. 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 Juan L. Lacaze?

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 Juan L. Lacaze today?

The sun rises at 07:05 and sets at 18:33 local time, giving 11h 27m of daylight.

What is the water temperature in Juan L. Lacaze today?

The sea surface at Juan L. Lacaze is around 13.3°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 Juan L. Lacaze today?

The significant wave height at Juan L. Lacaze is currently 0.5 m with a period of 3.0 s between crests. Individual sets can stack up to roughly twice that height, so allow a margin at exposed marks and anchorages.
