How We Calculate Conditions

We consider snorkeling conditions to be ideal when all of the following criteria, fetched from the Open-Meteo API, are met during daylight hours (between sunrise and sunset):

Wave height is less than 0.36 meters.
Wind speed is below 5.4 meters/second.
Sea surface temperature is between 20.6°C and 30.4°C.
Within ±72 min of high tide and currents ≤ 0.36 m/s.
