When to go
Ibiza and Formentera are diveable in some form yearround, but the easiest allround trip windows are May to June and September to October.
Best overall window
Comfortable air, improving or stillwarm water, active ferry and dive schedules, and fewer holiday crowds than peak summer.
Outside that window
Cooler water near winter lows around 14°C, shorter days, more wind, and fewer touristseason services.
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 regional shifts apply only to the selected scope.
| Area | Best months | Why it changes |
|---|---|---|
| Ibiza | May to June and September to October | Ibiza is the better base for flights, deep wrecks, nightlife, and yearround logistics. Main caution: Peak holiday weeks feel busier and book faster. |
| Formentera | May to June and September to October | Formentera is more sensitive to ferry timing, vehicle restrictions from June through September, and peak beach demand. Main caution: Peak holiday weeks feel busier and book faster. |
These do not replace the overall planner. Use them only if a specific animal or event is driving your trip dates.
