What is the best time of day to snorkel in Aitutaki Lagoon?

Snorkel in daylight, if possible in the morning before the wind picks up. Currents are often weaker near high slack tide. SnorkelForecast scores each daylight hour for Aitutaki Lagoon.

What is the best tide for snorkeling?

High slack tide, within about an hour of the high-tide peak, often has weaker currents. Strong low tides and tidal flow near channels or headlands reduce the score.

Jellyfish drift risk

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

Low · 28/100

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 is better in daylight, so night hours score lower.
