When to go
Loreto is diveable yearround, but the experience shifts with wind and water temperature.
Best overall window
Drier weather, comfortable days, and peak whalewatching. Expect occasional Norte winds around 30 km/h that can roughen the bay.
Outside that window
Hotter, more humid conditions and tropicalstorm risk later in summer. Water can reach 30°C but keep a close eye on forecasts.
Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.
The overall row stays visible so you can compare it against the currently selected scope.
