In the Alcarria de Guadalajara, heat is the top reason for a warning, closely followed by storms and rain. July and August hold most of the year; in summer 2022 warnings ran back to back from 20 July to 13 August.

Winter is calmer but has its moment: in January 2021, storm Filomena put the zone on red for snow two days running, followed by a red for cold on 12 January. They are the zone's only red warnings in the last eight years.

Guadalajara has 92,834 inhabitants and sits in the Alcarria de Guadalajara warning zone (Guadalajara). Warnings are issued for the whole zone: it shares them with 3 other towns, such as Azuqueca de Henares, Alovera and Cabanillas del Campo.

If you live in Guadalajara or are thinking of moving

With 9.9 orange or red days a year, serious warnings come a few times a year, nearly always in the same seasons.
Plan around summer: a cool home and morning activities in July and August.
Summer storms are the second reason for a warning: keep an eye on the afternoon forecast.
Winter brings few warnings, but a heavy snowfall can bring the zone to a halt.

In short

A summer that shows in the warnings and a quiet winter with the odd snow scare.

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.
