1 = most warnings
The Ibiza and Formentera zone is among Spain's most-warned zones. No single phenomenon dominates: rain, wind, storms and heat share the year, with August the busiest month.
The serious stuff is rare: one red heat day in August 2022 and one red rain day in September 2025. The rest, mostly yellow.
Ibiza has 55,337 inhabitants and sits in the Ibiza y Formentera warning zone (Ibiza y Formentera). Warnings are issued for the whole zone: it shares them with 2 other towns, such as Santa Eulària des Riu and Sant Antoni de Portmany.

If you live in Ibiza or are thinking of moving
- With 13 orange or red days a year, serious warnings are part of the calendar: it pays to know when they come.
- You'll see warnings often, nearly always yellow.
- If you sail, wind and sea warnings matter most.

How this was made
Everything comes from the archive of official AEMET warnings that Climaviso has kept since June 2018: each day counts once, at the highest level the zone had. A warning is a forecast, not damage or a measurement, and it's issued for the whole zone, not your street. We don't cover measured temperatures or rainfall: only when, and why, a warning was issued.
