Planning your day in Zaragoza? Here you will find the latest weather information, including up-to-date data, forecasts, and useful charts to make your stay as comfortable as possible.

The climate in Zaragoza is characterised as semi-arid (steppe) with features of a continental Mediterranean climate. This means the city experiences significant seasonal temperature fluctuations. Summers are hot and mostly dry, while winters are cool but not severe. Rainfall throughout the year is low, making Zaragoza one of the driest regions in Spain.

The city has four distinct seasons. Summer months, especially July and August, are distinguished by high temperatures, often exceeding 30°C, and minimal rainfall. Winter, from December to February, brings cool weather with average temperatures around 7-9°C, occasionally with night frosts, but snow falls rarely. Spring and autumn are transitional seasons with more moderate and pleasant temperatures, although precipitation remains low during these periods too.

One of the notable features of Zaragoza's weather is its aridity. Average monthly rainfall rarely exceeds 1-2 mm, and the number of rainy days per month is also low. This makes the city attractive for those who prefer sunny weather, but it also means travellers should be prepared for dry air, especially during the summer period.

The climate in Zaragoza is characterised by noticeable seasonal temperature fluctuations. The annual temperature range is quite wide: from cool winter months to hot summers. The coldest month is usually January, with an average temperature of about 7.1°C, when nightly lows can drop to 2.8°C and daily highs reach an average of 11.5°C. Conversely, the peak heat occurs in July and August. In July, the average temperature is 26.6°C, with daily highs often exceeding 30°C and reaching 34.0°C, and nightly lows around 19.1°C. August is very similar, with an average temperature of 26.2°C.

Summer months in Zaragoza, especially June, July, and August, are distinguished by hot and predominantly dry weather. Daytime temperatures regularly rise above 30°C, creating true summer heat conditions. However, significant diurnal temperature variations are observed: the difference between daily highs and nightly lows can be 13-15°C. This means that even after a very hot day, evenings and nights can bring pleasant coolness as the temperature drops to 16-19°C.

Winter in Zaragoza, covering December, January, and February, is mild and cool, but not freezing. Average temperatures during this period range from 7.1°C in January to 9.4°C in February. Night temperatures can approach freezing point, especially in January (average low 2.8°C), however, daily highs usually remain above zero, reaching 11-15°C. Diurnal temperature fluctuations in winter are also noticeable, though less pronounced than in summer, averaging 8-10°C. This means days can be relatively mild, while nights and early morning hours are quite cold.

Zaragoza is distinguished by an arid climate, where precipitation falls in very small amounts throughout the year. There is no clearly defined rainy season here, as total monthly rainfall remains consistently low. Nevertheless, there are some fluctuations in the frequency of rainy days from month to month.

The highest amount of precipitation, albeit modest (2 mm per month), usually falls in April, October, and November. April and November are also the months with the highest number of days with precipitation – an average of 8 days each. In March, June, and October, one can also expect about 7 rainy days. The nature of the precipitation, given its small quantity, is predominantly light – this could be drizzle or brief, light showers.

The "driest" months in terms of rain frequency are February, July, and August, when there are on average only 4 days with precipitation. In January, May, September, and December, rainfall usually does not exceed 1 mm, and the number of rainy days varies from 5 to 6. Given the average winter temperatures and extremely low precipitation levels, snowfall in Zaragoza is a rare and insignificant phenomenon.

Overall, when travelling to Zaragoza, one should count on predominantly dry weather. Brief and light rains are possible in any season, but they are unlikely to become a serious obstacle to exploring the city, making it comfortable to visit at any time of year for those who value sunny days.

When planning a trip to Zaragoza, it is important to consider local climate specifics to pack your luggage correctly. Summer here, especially in July and August, is hot, with an average temperature of around 26°C and maximum values reaching 33-34°C. During this time, you will need light, breathable clothing made from natural fabrics, a hat, sunglasses, and high SPF sunscreen. Evenings can be slightly cooler, so a light cardigan or shawl would not go amiss. Winter months, from December to February, are noticeably colder: the average temperature stays around 7-9°C, and nightly lows can drop to 2-4°C. For a winter trip, pack a warm jacket, sweaters, a hat, gloves, and a scarf. The principle of layering clothing will be relevant at any time of year, as day and night temperatures can differ significantly.

Spring (March-May) and autumn (September-November) in Zaragoza are characterised by moderate temperatures that gradually rise or fall respectively. During these periods, you will find a mid-season jacket, jeans or thick trousers, t-shirts, and light sweaters useful. Although rainfall in Zaragoza is low (1-2 mm per month), rainy days do happen regularly (from 4 to 8 days per month). Therefore, it is worth having a compact umbrella or a light raincoat with you, especially in the spring and autumn months, as well as in November. Regardless of the season, comfortable walking shoes are a must-have attribute for a tourist, as you will be walking a lot while sightseeing in the city.
