The Ebro valley has everything for warnings. In summer, heat and storms; from November to March, wind, the city's cierzo, which makes Zaragoza one of the cities on this list with the most wind warnings; and in winter, fog as well.
If there were a prize for variety, Zaragoza would be a favourite: it has had red warnings for heat, rain and snow. The snow ones, on 9 and 10 January 2021, during storm Filomena.
Zaragoza has 693,091 inhabitants and sits in the Ribera del Ebro de Zaragoza warning zone (Zaragoza). Warnings are issued for the whole zone: it shares them with 9 other towns, such as Utebo, Caspe and Zuera.

If you live in Zaragoza or are thinking of moving
- With 22 orange or red days a year, serious warnings are part of the calendar: it pays to know when they come.
- Get ready for wind: the cierzo doesn't always reach warning level, but you'll feel it in your clothes, on your bike and in your heating bill.
- Summers bring heat and storms in nearly equal parts: going from a heat warning to a storm warning in the same week is not unusual.
- In winter, fog can disrupt roads and flights for several days in a row.
In short
Among the busiest cities on this list for warnings, with a bit of everything and something for every season.

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.
