Fishing barometer

1017 hPa ↗ 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 1017 hPa max 1018 hPa 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.

High exposure — protection is essential: hat, sunglasses and SPF 30+, and take shade around midday.

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.

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.

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

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.

High tide turn

01:20 – 03:20

Water peaks at 02:20 then starts to fall.

Prime window

07:40 – 09:40

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

High tide turn

14:30 – 16:30

Water peaks at 15:30 then starts to fall.

Low tide turn

20:20 – 22:20

Water bottoms out at 21:20 then starts to rise.

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

Frequently asked questions

Tides, coefficients and fishing times for Formia, explained.

What time is high tide in Formia today?

High water at Formia today is at 02:20 and 15:30. 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 Formia?

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 31 (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 Formia today?

The sun rises at 06:34 and sets at 19:33 local time, giving 12h 59m of daylight.

What is the water temperature in Formia today?

The sea surface at Formia is around 28.4°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 Formia today?

The significant wave height at Formia is currently 0.4 m with a period of 4.5 s between crests. Individual sets can stack up to roughly twice that height, so allow a margin at exposed marks and anchorages.
