Rouen

Planning a trip or a stroll through the city of Rouen? Here you will find the latest weather information, including detailed forecasts and clear charts to help you plan your day in the best possible way.

The climate in Rouen, located in France, can be described as temperate marine. This means the city enjoys relatively mild weather throughout the year, without extreme temperature peaks or drops. Travelers should expect comfortable conditions for walking, but also be prepared for changeable weather and precipitation.

Rouen experiences four distinct seasons. Winters here are cool and damp, with average temperatures around 5-6°C; while severe frosts are rare, cloudy and rainy days are frequent. Spring brings a gradual warming, the air becomes fresher, and nature blooms, though the chance of precipitation remains. Summer in Rouen is warm and pleasant but not sweltering, with average temperatures around 17-19°C—an ideal time to explore the city. In autumn, temperatures gradually decrease, days become shorter, and the number of rainy days may slightly increase, especially by November.

One of the key features of Rouen's weather is the high probability of precipitation throughout the year. Data shows a significant number of "wet days" each month—ranging from 10 days in July to 16 days in March and December. This indicates that even with a low total amount of precipitation (listed as 2-3 mm per month), light rain or drizzle can be a frequent occurrence. Therefore, carrying an umbrella and waterproof clothing is advisable for a trip to Rouen at any time of year.

Rouen experiences a temperate climate with noticeable seasonal temperature changes throughout the year. The coldest months are January, with an average temperature of 5.0°C (lows around 2.6°C, highs of 7.4°C), and December, where the average temperature is 6.1°C (minimum 4.0°C, maximum 8.3°C). Conversely, the warmest months are traditionally July, with an average temperature of 18.7°C and highs of up to 23.3°C, and August, where the average temperature stays at 18.6°C and the maximum reaches 22.9°C.

The summer months in Rouen, from June to August, are characterized by pleasantly warm weather. The average daily temperature in June is around 17.0°C, gradually rising to 18.7°C in July. Daytime highs in the height of summer usually range from 21-23°C, creating comfortable conditions for outdoor activities. At night, the temperature drops to 12-14°C, bringing refreshing coolness. The difference between day and night temperatures in summer is quite noticeable, averaging 8-9°C, which is worth considering when planning evening activities.

The winter period in Rouen, covering December, January, and February, features cool but generally mild weather. Average temperatures in these months range from 5.0°C in January to 6.2°C in February. During the day, the thermometer usually shows between 7°C and 9°C, while at night it drops to 2.6°C - 4.0°C. Although average minimum temperatures remain above freezing, individual nights can be frosty. Diurnal temperature fluctuations in winter are less pronounced than in summer, at approximately 4-6°C. Spring and autumn are transitional seasons with gradual changes in temperature patterns.

In Rouen, precipitation occurs throughout the year, and the city does not have a pronounced rainy or dry season in terms of total rainfall volume. Monthly precipitation is quite low and stable: in January, October, November, and December, an average of 3 mm falls, while in the other months, from February to September, this figure is about 2 mm. This suggests that heavy downpours are not typical for Rouen.

Despite the low total volume, the frequency of rainy days in Rouen is quite high. The highest number of days with precipitation occurs in March and December—averaging 16 wet days in each of these months. Rain is also relatively frequent in October (15 days), and January and November (14 days each). The "driest" month in terms of rainfall frequency is July, which has about 10 rainy days, meaning there is still a roughly one-in-three chance of catching rain.

Given the combination of low volume and a high number of rainy days, it can be assumed that Rouen is characterized by frequent but light and brief rain or drizzle. In the winter months, when average minimum air temperatures range from +2.6°C to +4.0°C (January, December), precipitation falls primarily as rain. Although the data provided does not specify snowfall, at these temperatures, the possibility of sleet or wet snow mixed with rain cannot be entirely ruled out, though rain remains the primary form of winter precipitation.

When planning a trip to Rouen, it's important to consider its temperate marine climate, characterized by mild temperatures and frequent precipitation throughout the year. Regardless of the season, the key packing principle should be layering. This will allow you to easily adapt to weather changes during the day. Be sure to bring comfortable waterproof shoes, as you'll be doing a lot of walking along the city's charming streets, as well as a compact umbrella or a light raincoat—these will come in handy even in summer, given there are more than 10 rainy days in almost every month.

In the winter months (December to February), when average temperatures hover around 5-6°C, you will need warm outerwear (preferably waterproof and windproof), sweaters, fleece jackets, as well as a hat, scarf, and gloves. In spring (March-May) and autumn (September-November), the weather in Rouen can be changeable, with average temperatures from 8°C to 16°C; layering is particularly relevant here: a light or mid-weight jacket, jumpers, and cardigans. In summer (June-August), the city is usually pleasantly warm, with average high temperatures reaching 21-23°C. Light clothing such as T-shirts, shorts, and dresses is suitable for this period, but don't forget to pack a light jacket or sweater for evening walks or cooler days. Sunscreen and a hat will also be useful on clear summer days.
