Historic wrecks in a UNESCO bay, lava caves, and seamount day trips in the Azores
When to go
Terceira sits in the mid-Atlantic, so wind and swell often matter more than temperature.
Best overall window
Warmest water (often 20°C to 25°C) and the best odds for calm-boat days.
Outside that window
More Atlantic storms and swell, cooler water (down toward 14°C), and more trip cancellations.
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.

These do not replace the overall planner. Use them only if a specific animal or event is driving your trip dates.
