When to go

Best time to visit Loreto

Loreto is diveable yearround, but the experience shifts with wind and water temperature.

Best overall window

November - May

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.

Choose your trip style

Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.
