Fishing barometer

1022 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 1020 hPa max 1024 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.

High exposure — protection is essential: hat, sunglasses and SPF 30+, and take shade around midday.

Little risk — most people need no sun protection.

Wear a hat, sunglasses and SPF 30+, and take shade around midday.

The sea surface holds around 24.3° today, moving between 24.2° and 24.4°. 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

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

03:10 – 05:10

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

Low tide turn

08:40 – 10:40

Water bottoms out at 09:40 then starts to rise.

Prime window

15:20 – 17:20

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

Frequently asked questions

Tides, coefficients and fishing times for Vieux Grand Port, explained.

What time is high tide in Vieux Grand Port today?

High water at Vieux Grand Port today is at 04:10 and 16:20. 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 Vieux Grand Port?

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 29 (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 Vieux Grand Port today?

The sun rises at 06:15 and sets at 18:01 local time, giving 11h 46m of daylight.

What is the water temperature in Vieux Grand Port today?

The sea surface at Vieux Grand Port is around 24.2°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 Vieux Grand Port today?

The significant wave height at Vieux Grand Port is currently 2.2 m with a period of 8.0 s between crests. Individual sets can stack up to roughly twice that height, so allow a margin at exposed marks and anchorages.
