Fishing barometer

1016 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 1013 hPa max 1016 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.

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.

The sea surface holds around 27.8° today, moving between 27.5° and 28.0°. 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 13.8 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 Tuakau — plan around the major and minor periods below.

Major Peak activity

04:03 – 06:03

Moon overhead (lunar transit)

Overlaps sunrise or sunset
Minor Average activity

10:25 – 11:25

Moonset

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.

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

Frequently asked questions

Tides, coefficients and fishing times for Tuakau, explained.

What time is high tide in Tuakau today?

High water at Tuakau today is at 02:10 and 15:00. 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 Tuakau?

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 32 (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 Tuakau today?

The sun rises at 05:46 and sets at 17:42 local time, giving 11h 56m of daylight.

What is the water temperature in Tuakau today?

The sea surface at Tuakau is around 27.5°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 Tuakau today?

The significant wave height at Tuakau is currently 0.7 m with a period of 13.8 s between crests. Individual sets can stack up to roughly twice that height, so allow a margin at exposed marks and anchorages.
