Can you snorkel in Zakynthos today?

Yes. The next good snorkeling window in Zakynthos starts Wed 04:00 and lasts until 06:00. Around 75% of the next 72 hours are suitable.

What is the best time of day to snorkel in Zakynthos?

Snorkel during daylight, ideally in the morning before the wind picks up, and around high slack tide when water is clearest and currents are weakest. SnorkelForecast scores every daylight hour in Zakynthos so you can pick the calmest window.

What is the best tide for snorkeling?

High slack tide — within about an hour of the high-tide peak when currents are weakest — is the safest, clearest window. Strong low tides, strong tidal flow near channels or headlands, and large tidal-range days reduce score.

Jellyfish drift risk

Drift estimate from wind, swell, current and warm water.

Low · 32/100

Low drift risk now.

warm water supports seasonal jellyfish activity; surface drift/current is noticeable; local shoreline exposure is not mapped yet.

Sightings override the model: if you see small purple jellyfish with long trailing tentacles, treat them as sting-capable and give them space.

Scoring methodology (for technical users)

We score each hour from 0 to 1 using daylight and these weighted components:

Wave height (35%): best below 0.36m, then decreases as it rises.
Wind speed (25%): best below 5.4m/s, lower is better.
Sea surface temperature (15%): best within 20.6°C to 30.4°C.
Tide and currents (15%): best around slack/high-tide windows.
Daylight (10%): visibility and safety gate (outside daylight scores lower).
