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 1012 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.

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 Ushiro Wan — plan around the major and minor periods below.

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.

High tide turn

01:40 – 03:40

Water peaks at 02:40 then starts to fall.

Low tide turn

07:50 – 09:50

Water bottoms out at 08:50 then starts to rise.

High tide turn

13:40 – 15:40

Water peaks at 14:40 then starts to fall.

Prime window

19:30 – 21:30

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

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

Frequently asked questions

Tides, coefficients and fishing times for Ushiro Wan, explained.

What time is high tide in Ushiro Wan today?

High water at Ushiro Wan today is at 02:40 and 14:40. 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 Ushiro Wan?

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 34 (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 Ushiro Wan today?

The sun rises at 06:52 and sets at 20:09 local time, giving 13h 17m of daylight.

What is the water temperature in Ushiro Wan today?

The sea surface at Ushiro Wan is around 16.9°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 Ushiro Wan today?

The significant wave height at Ushiro Wan is currently 0.1 m with a period of 6.4 s between crests. Individual sets can stack up to roughly twice that height, so allow a margin at exposed marks and anchorages.
