Fishing barometer

1002 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 996 hPa max 1008 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.

The sea surface holds around 9.5° today, moving between 9.5° and 9.5°. 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.

Solunar theory rates today a slow day for fishing at Fossil River entrance — plan around the major and minor periods below.

Major Peak activity

Major Peak activity

Major period Minor period Daylight

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.

Frequently asked questions

Tides, coefficients and fishing times for Fossil River entrance, explained.

What time is high tide in Fossil River entrance today?

High water at Fossil River entrance today is at 04:20 and 17:30. 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 Fossil River entrance?

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 37 (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 Fossil River entrance today?

The sun rises at 08:11 and sets at 22:25 local time, giving 14h 14m of daylight.

What is the water temperature in Fossil River entrance today?

The sea surface at Fossil River entrance is around 9.5°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.
