Fishing barometer

1007 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 1005 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.

High

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

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.

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.

Biggest tides: 9–12 Sep (coef 104) · Quietest stretch: 18–19 Sep (coef 20) · Morning 39 · afternoon 31. Predicted levels run between -1.0 m and 1.1 m this month.

Heights are metres above the station's chart datum, so the biggest tides can dip just below zero. Every time shown is Natona local time, with daylight saving already applied.

Frequently asked questions

Tides, coefficients and fishing times for Natona, explained.

What time is high tide in Natona today?

High water at Natona today is at 08:40 and 21:10. 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 Natona?

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 31 (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 Natona today?

The sun rises at 05:43 and sets at 18:14 local time, giving 12h 31m of daylight.

What is the water temperature in Natona today?

The sea surface at Natona is around 30.0°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 Natona today?

The significant wave height at Natona is currently 0.5 m with a period of 8.2 s between crests. Individual sets can stack up to roughly twice that height, so allow a margin at exposed marks and anchorages.
