Fishing barometer

29.91 inHg → 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 29.91 inHg max 30.03 inHg 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.

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.

Bite windows

Thursday 3 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

03:30 – 05:30

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

Low tide turn

07:20 – 09:20

Water bottoms out at 08:20 then starts to rise.

High tide turn

14:20 – 16:20

Water peaks at 15:20 then starts to fall.

Low tide turn

22:10 – 23:59

Water bottoms out at 23:10 then starts to rise.

Frequently asked questions

Tides, coefficients and fishing times for Kirby Park, Elkhorn Slough, explained.

What time is high tide in Kirby Park, Elkhorn Slough today?

High water at Kirby Park, Elkhorn Slough today is at 04:30 and 15:20. 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 Kirby Park, Elkhorn Slough?

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 38 (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 Kirby Park, Elkhorn Slough today?

The sun rises at 06:39 and sets at 19:32 local time, giving 12h 52m of daylight.

What is the water temperature in Kirby Park, Elkhorn Slough today?

The sea surface at Kirby Park, Elkhorn Slough 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 Kirby Park, Elkhorn Slough today?

The significant wave height at Kirby Park, Elkhorn Slough is currently 1.1 m with a period of 10.5 s between crests. Individual sets can stack up to roughly twice that height, so allow a margin at exposed marks and anchorages.
