Fishing barometer

29.88 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 29.85 inHg max 30.06 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.

Swell

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

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.

Frequently asked questions

Tides, coefficients and fishing times for Old Saybrook, explained.

What time is high tide in Old Saybrook today?

High water at Old Saybrook today is at 03:30 and 15:50. 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 Old Saybrook?

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 40 (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 Old Saybrook today?

The sun rises at 06:17 and sets at 19:18 local time, giving 13h 01m of daylight.

What is the water temperature in Old Saybrook today?

The sea surface at Old Saybrook is around 22.7°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 Old Saybrook today?

The significant wave height at Old Saybrook is currently 0.4 m with a period of 3.5 s between crests. Individual sets can stack up to roughly twice that height, so allow a margin at exposed marks and anchorages.
