Climate in Zaragoza (Aragon)

The climate of Zaragoza is continentalized Mediterranean, with quite mild winters (but with some cold periods) and hot, sunny summers. The rains are scarce.
The city is the capital of Aragon and is located in northeastern Spain, at an altitude between 200 and 290 meters (650 and 950 feet).
The climate is not very different from that of Madrid, as Zaragoza is located at a lower altitude but at a higher latitude. In addition, in Zaragoza and in the Ebro valley (the longest river in Spain, which runs through the city), a cold and dry wind from the north-west, the cierzo, can blow, bringing the cold air masses that originally come from the Atlantic.

The average temperature of the coldest months (January, December) is of 7 °C (45 °F), that of the warmest months (July, August) is of 25.5 °C (78 °F).

Precipitation amounts to 330 millimeters (13 inches) per year.

The winter, from December to February, is quite mild, and it is particularly dry. However, it is often cold at night, and fog can form, especially in December.
Also, there can sometimes be cold periods. On the coldest nights of the year, the temperature typically drops to -4/-5 °C (23/25 °F). The extreme minimum is -11.5 °C (11.5 °F) and was recorded in February 1963. From 2000 to 2020, the temperature dropped to -9.5 °C (15 °F) in December 2001.
Snow in Zaragoza is quite rare, as the altitude is low and the winter is dry, but it can sometimes occur. A snowfall can be observed every year or so, but it is rare that it accumulates on the ground. However, in February 2005 and January 2021, 20 cm (8 in) of snow fell, while in February 2018, snow depth reached 10 cm (4 in). The most abundant snowfall occurred in 1932, with a thickness of 30 cm (12 in).

The summer, from June to August or early September, is very hot and sunny, with rare thunderstorms. When cool air from the Atlantic manages to enter the Ebro Valley, there can be windy days, with highs below 30 °C (86 °F), and quite cool nights.
However, due to its location in a valley and far from the sea, the city is particularly prone to heat waves. On the hottest days of the year, the temperature typically reaches 39/40 °C (102/104 °F), however, it can sometimes exceed these values. In July 2015, it even reached 44.5 °C (112 °F), while in 2019, it reached 43 °C (109.5 °F) at the end of June.
