Fishing barometer

1014 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 1014 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.

UV index

solar protection

UV 9

Very high

Very high exposure — unprotected skin burns quickly. Cover up, reapply sunscreen often and keep out of the midday sun.

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.

Best fishing times today

Slow

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

Major Peak activity

04:36 – 06:36

Moon overhead (lunar transit)

Overlaps sunrise or sunset
Minor Average activity

11:22 – 12:22

Moonset

Major Peak activity

17:06 – 19:06

Moon underfoot (opposing transit)

Overlaps sunrise or sunset
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 Purnama, explained.

What time is high tide in Purnama today?

High water at Purnama today is at 10:50 and 22:30. 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 Purnama?

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 Purnama today?

The sun rises at 06:09 and sets at 18:17 local time, giving 12h 08m of daylight.
