Weather in Lorient

Planning a trip or a walk around Lorient? In this section, you will find the most up-to-date information on weather conditions, including detailed forecasts and visual charts.

The climate in Lorient, located on the Atlantic coast of France, can be described as temperate maritime. This means there are no drastic temperature changes, and the weather is generally mild year-round. Thanks to the influence of the ocean, winters here are not harsh, and summers are comfortable without sweltering heat.

Four seasons are clearly distinguishable in Lorient. Winter (December-February) is mild, with average temperatures around 7-9°C, and is the wettest period of the year in terms of rainy days, although total precipitation remains low. Spring (March-May) brings gradual warming, with average temperatures rising to 11-14°C. Summer (June-August) is the warmest time of the year, with average temperatures around 17-18.5°C and maximum values rarely exceeding 22°C; it is also the sunniest and least rainy period. Autumn (September-November) is characterized by a gradual decrease in temperature and an increase in the number of rainy days.

A specific feature of Lorient's climate is the relatively small amount of precipitation in millimetres, but a rather frequent occurrence of it in the form of drizzle or light rain, especially during the autumn-winter period. Thus, tourists should be prepared for changeable weather and carry an umbrella or raincoat, particularly if the trip is planned for months other than summer.

The climate in Lorient is characterized by moderate temperatures throughout the year, which is typical for the coast. The annual range of average temperatures extends from approximately 7.4°C in January to 18.5°C in July. January is the coldest month, when average minimum temperatures drop to 5.4°C, and maximums barely reach 9.4°C. Conversely, the peak heat occurs in July and August, with average temperatures of 18.5°C and 18.3°C respectively, and daytime highs comfortably sitting around 21-22°C.

The summer period in Lorient, covering June, July, and August, offers pleasant warmth without exhausting heat. Daytime temperatures during this time usually range from 20°C to 22°C, while nights bring refreshing coolness with temperatures around 13-15°C. This makes summer evenings particularly comfortable. Winters in the city are mild and damp. From December to February, average night temperatures rarely drop significantly below 5-7°C, and during the day the air warms up to 9-10.5°C. Diurnal temperature variations both in winter and summer are generally small, averaging 4-6°C, which indicates the moderating influence of the Atlantic Ocean.

In the city of Lorient, precipitation occurs throughout the year, but its intensity and frequency vary depending on the season. In general, a distinct season of torrential rains is not characteristic of Lorient; rather, precipitation here most often takes the form of light rain or drizzle distributed over several days.

The greatest amount of precipitation, although remaining comparatively small, falls during the autumn-winter period. Thus, November and December are the months with the maximum average amount of precipitation – about 4 mm in each. These same months, as well as March and October, are also distinguished by the highest number of rainy days – on average 15 days per month. January is also quite damp, with approximately 14 rainy days and 3 mm of precipitation.

Summer months, on the contrary, are the driest. July stands out as the month with the fewest rainy days (on average 8) and minimum precipitation volume (about 2 mm). August is also relatively dry: about 9 rainy days and 2 mm of precipitation. Spring months, such as April and May, show a moderate amount of precipitation (2 mm) and about 10-11 rainy days, making them a transitional period between the wetter winter and the dry summer.

When planning a trip to Lorient, it is important to consider its temperate maritime climate, characterized by mild weather year-round, but with a high probability of precipitation and winds, especially in the autumn-winter period. Regardless of the time of your visit, a waterproof windbreaker or light raincoat and an umbrella will become your indispensable companions. The number of rainy days here is significant even in the summer months. Also, be sure to take comfortable closed shoes, preferably with non-slip soles, for walking around the city and along the coast.

In summer, from June to August, the average temperature hovers around 17-19°C. You will need light clothing: t-shirts, shorts, dresses, but do not forget a light sweater or cardigan for evening coolness or cloudy days. Sunscreen and a hat will also come in handy. In the off-season (spring and autumn), the weather can be changeable, so the principle of layering in clothing will be very useful: t-shirts, long-sleeved shirts, and jumpers that can be easily removed or put on. In winter (December-February), the temperature holds at an average of about 7-9°C. For this period, pack warmer items: sweaters, a fleece jacket, warm trousers, as well as a hat, scarf, and gloves, especially if you are sensitive to damp and windy weather.
