Introduction

---

In Aragon, an autonomous community and province of Spain, there are the following climatic zones:
- the Pyrenean range in the far north, on the border with France, characterized by an alpine climate (cold mountain climate);
- the pre-Pyrenean range in the north, in valleys and slopes at low-mountain elevations (see Jaca, Bielsa), where the weather is cold in winter and mild in summer, with some hot days, and relatively abundant rainfall;
- all the center-south, at medium-low altitudes, is characterized by an arid or semi-arid climate, and more or less warm depending on altitude, so we have a transitional Mediterranean (slightly continental) climate in the Ebro Valley (see Zaragoza), with quite mild winters and hot summers, often scorching, while above 600 meters (2,000 feet), there is a semi-continental climate, similar to that of the central plateau of Spain (meseta);
- in the center-south, there is another mountain range, the Iberian System (Sistema Ibérico): here, the climate becomes colder with increasing altitude, while rain (and snow in winter) becomes more abundant, so much so that the mountains are covered with forests.

Pyrenees

---

In the far north, on the border with France, we find the chain of the Pyrenees; the highest peak of the entire chain, Pico de Aneto, 3,404 meters (11,168 feet) high, is located in Aragon. Above 2,700 meters (9,000 feet), there are glaciers, which are among the most southern in Europe (together with the small Calderone glacier in Abruzzo, Italy, and the glaciers of Caucasus).
In the Pyrenean area, we find the Ordesa y Monte Perdido National Park.
In the area at the foot of the Pyrenees, at the same altitude, the climate is cooler than in the south-central part of the region; in addition, this area is exposed to cold air outbreaks in winter, with strong winds.

Jaca

In Jaca, located at the foot of the Pyrenees, at 800 meters (2,600 feet) above sea level, the average temperature ranges from 2.5 °C (36.5 °F) in January to 17.5 °C (63.5 °F) in July and August; therefore, winter is cold, and sometimes, there can be heavy snowfalls. Although the summer averages are not high, there can be some hot days.
Here are the average temperatures.

In Jaca, 780 millimeters (30.5 inches) of rain or snow fall, well distributed throughout the year, with a maximum in May of 85 mm (3.3 in) and a minimum in July of 45 mm (1.8 in). The latter is not very pronounced, since a few Atlantic fronts can affect this area even in summer, in addition, some thunderstorms can erupt in the afternoon.

Center-south

Huesca

In Huesca, located in the center-north, at no great distance from the Pyrenees and at 450 meters (1,475 ft) of altitude, we already enter the zone with a semi-arid climate and hot summers. Here, the monthly average temperature ranges from 5 °C (41 °F) in January to 24 °C (75 °F) in July and August. In winter, there can be cold spells, with night frosts, and when the weather is stable, cold and foggy periods may occur. In summer, days with intense heat are possible, although the air is dry and nights remain cool.
Here are the average temperatures.

In Huesca, 485 mm (19 in) of rain fall per year, with two maxima in spring and autumn, and quite poor rains, but not entirely absent, in winter (when they are a bit more common but not abundant) and in summer (when rare thunderstorms can break out). Here is the average precipitation.

Zaragoza

Further to the south, we find Zaragoza, located in the Ebro Valley, 250 meters (820 feet) above sea level, ie in the area where the altitude is lower, and the climate can be described as transitional Mediterranean. Here, the average temperature ranges from 6.5 °C (43.5 °F) in January to 25.5 °C (78 °F) in July and August. In winter, nights are often cold, with possible slight frosts. In summer, hot days are frequent, however, the air is dry, and the temperature drops considerably at night.
In Zaragoza and in the Ebro valley, a cold, dry north-west wind can blow, the cierzo.
Here are the average temperatures.

In Zaragoza, only 330 mm of rain fall annually; winter is particularly dry, in fact, only 20 mm (0.8 in) of rain fall each month. Here is the average precipitation.

The amount of sunshine in Zaragoza is not bad, in fact, some sunny day can occur all year round, although it is better, as happens in Mediterranean climates, in late spring and summer, especially from May to August, when sunny days prevail. Here are the average sunshine hours per day.

East of Zaragoza, we find the Monegros Desert (which is actually a semi-desert zone), where rainfall drops below 300 mm (12 in) per year.



In the center-south of Aragon, the altitude rises again because of the presence of the mountain chain called Sistema Ibérico, whose highest point is San Miguel, in the Moncayo Massif, 2,314 meters (7,592 feet) high.

Molina de Aragon

In Molina de Aragon, at 1,050 meters (3,450 feet), the average temperature ranges from 2.5 °C (36.5 °F) in January to 20 °C (68 °F) in July and August. You can notice the cold nights in the winter months, and the wide temperature range in summer, when nights remain very cool. Here are the average temperatures.

In Molina de Aragon, average precipitation (rain or snow) amounts to 485 mm (19 in) per year, with a peak in spring and a small amount in winter. Here is the average precipitation.

Teruel

Further to the south-east, in Teruel, the capital of the province, 900 meters (2,950 feet) above sea level, the average temperature ranges from 3.5 °C (38.5 °F) in January to 22.5 °C (72.5 °F) in July. Here are the average temperatures.

In an average year, 390 mm (15.3 in) of rain fall in Teruel. The driest season is even the winter. Here is the average precipitation.

Best Time

The best time to visit the Pyrenees and the valleys at the foot of the mountains is summer, since it is the warmest (or mildest) and sunniest period of the year.
In the areas at low altitude of central and southern Aragon (see Huesca, Zaragoza), since the summer is hot, you may prefer spring and autumn (although the rains are more frequent), especially in May, and from mid-September to mid-October.
Those who can stand the heat can choose July and August also in the center-south, but they should be ready to stroll around the cities in hot weather. Given the high temperature range, except perhaps in Zaragoza, also in the center-south, it's better to bring a sweatshirt for the evening even in summer.
