Fishing barometer

29.68 inHg ↗ 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 29.65 inHg max 29.94 inHg 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.

Frequently asked questions

Tides, coefficients and fishing times for North Bay, Stuart Island, explained.

What time is high tide in North Bay, Stuart Island today?

High water at North Bay, Stuart Island today is at 02:00 and 13:30. 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 North Bay, Stuart Island?

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 37 (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 North Bay, Stuart Island today?

The sun rises at 07:40 and sets at 21:55 local time, giving 14h 15m of daylight.

What is the water temperature in North Bay, Stuart Island today?

The sea surface at North Bay, Stuart Island is around 12.2°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 North Bay, Stuart Island today?

The significant wave height at North Bay, Stuart Island is currently 1.0 m with a period of 4.1 s between crests. Individual sets can stack up to roughly twice that height, so allow a margin at exposed marks and anchorages.
