Fishing barometer

1009 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 1007 hPa max 1011 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 8

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.

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.

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.

Solunar theory rates today a slow day for fishing at Playa Buena Vista — 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.

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.

Low tide turn

00:00 – 01:10

Water bottoms out at 00:10 then starts to rise.

Prime window

05:30 – 07:30

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

Low tide turn

11:50 – 13:50

Water bottoms out at 12:50 then starts to rise.

Prime window

18:00 – 20:00

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

Frequently asked questions

Tides, coefficients and fishing times for Playa Buena Vista, explained.

What time is high tide in Playa Buena Vista today?

High water at Playa Buena Vista today is at 06:30 and 19:00. 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 Playa Buena Vista?

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 39 (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 Playa Buena Vista today?

The sun rises at 05:32 and sets at 17:49 local time, giving 12h 17m of daylight.

What is the water temperature in Playa Buena Vista today?

The sea surface at Playa Buena Vista is around 30.8°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 Playa Buena Vista today?

The significant wave height at Playa Buena Vista is currently 1.1 m with a period of 11.4 s between crests. Individual sets can stack up to roughly twice that height, so allow a margin at exposed marks and anchorages.
