Fishing barometer

1013 hPa → Stable
  • Rising Very good Rising pressure after a low signals settling weather — fish feed confidently and this is often the best barometer window of all.
  • Stable Normal activity — today 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 1010 hPa max 1015 hPa Hover, tap or arrow-key the line to read any hour.

The barometer is holding steady. Expect routine feeding behaviour, with the usual peaks around tide changes and the solunar periods rather than any pressure-driven surge.

Moderate exposure — wear sunglasses and apply SPF 30+ if you are out over the middle of the day.

Little risk — most people need no sun protection.

Wear a hat, sunglasses and SPF 30+, and take shade around midday.

The sea surface holds around 20.3° today, moving between 20.2° and 20.5°. 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.

Swell

Most frequent waves 0.3 m About half the significant height — what you will see most of the time.
Significant height 0.7 m The standard forecast figure — roughly 1 wave in 7 runs higher, on a 4.0 second period.

These figures describe the swell out in open water. Closer to the beach the waves shift with the shape of the coastline and the seabed, though in most spots they end up broadly similar.

Best fishing times today

Slow

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

Major Peak activity

03:51 – 05:51

Moon overhead (lunar transit)

Overlaps sunrise or sunset
Minor Average activity

Moonrise

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

03:50 – 05:50

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

Prime window

15:00 – 17:00

Frequently asked questions

Tides, coefficients and fishing times for Hamanaka, explained.

What time is high tide in Hamanaka today?

High water at Hamanaka today is at 04:50. 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 Hamanaka?

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 33 (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 Hamanaka today?

The sun rises at 05:00 and sets at 18:08 local time, giving 13h 08m of daylight.

What is the water temperature in Hamanaka today?

The sea surface at Hamanaka is around 20.3°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 Hamanaka today?

The significant wave height at Hamanaka is currently 0.7 m with a period of 4.0 s between crests. Individual sets can stack up to roughly twice that height, so allow a margin at exposed marks and anchorages.
