Fishing barometer

1013 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 1011 hPa max 1015 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 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.

The sea surface holds around 30.9° today, moving between 30.7° and 31.2°. 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

Best fishing times today

Slow

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

Major Peak activity

04:54 – 06:54

Moon overhead (lunar transit)

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.

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

04:30 – 06:30

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

High tide turn

09:40 – 11:40

Water peaks at 10:40 then starts to fall.

Prime window

15:30 – 17:30

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

High tide turn

22:50 – 23:59

Water peaks at 23:50 then starts to fall.

Frequently asked questions

Tides, coefficients and fishing times for Ujung Batu, explained.

What time is high tide in Ujung Batu today?

High water at Ujung Batu today is at 10:40 and 23:50. 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 Ujung Batu?

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 Ujung Batu today?

The sun rises at 06:26 and sets at 18:36 local time, giving 12h 10m of daylight.

What is the water temperature in Ujung Batu today?

The sea surface at Ujung Batu is around 30.8°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 Ujung Batu today?

The significant wave height at Ujung Batu is currently 0.9 m with a period of 11.6 s between crests. Individual sets can stack up to roughly twice that height, so allow a margin at exposed marks and anchorages.
