Temperature Ranges Across France

In September, France begins to cool down as it moves from the summer heat into milder autumn temperatures. However, the extent of this change varies widely across different regions:

North France: Here, temperatures start to drop more noticeably, with averages ranging from 12°C to 20°C. Mornings and evenings can feel particularly crisp.

South France: The Mediterranean influence keeps the south warmer, with average temperatures lingering between 15°C and 25°C. Coastal areas especially retain the summer warmth, making it a favorite for late-season vacationers.

East France: Eastern areas, especially near the Alps, experience a range of temperatures, from cooler mountainous regions averaging 10°C to warmer lowland areas around 20°C.

West France: The Atlantic coast brings mild weather, with temperatures averaging between 13°C and 22°C, influenced by the oceanic climate.

Central France: The heartland sees average temperatures similar to the north, between 12°C and 21°C, with a gradual decrease in warmth as the month progresses.

Rainfall and Frequency of Rainy Days

September can be relatively dry, but rainfall varies by region.

North and West France: These areas see more frequent rain, although it’s usually not as heavy as in the winter months. Packing an umbrella or a light raincoat is advisable.

South France: Rainfall is less frequent here, but when it does rain, it can be heavy and sometimes accompanied by storms, particularly along the Mediterranean.

Central and East France: Expect moderate rainfall, with occasional showers breaking the otherwise sunny days.

Daylight and Changing Days

As autumn approaches, the days gradually become shorter. By the end of September, there’s a noticeable difference in daylight hours.

Early sunsets and later sunrises mean cooler evenings and mornings, so it’s wise to prepare for a wider range of temperatures throughout the day. This change in light also brings beautiful early autumnal hues, making it a picturesque time to explore France’s outdoor beauty.

What to Wear: September Wardrobe Tips

General Clothing Advice for Fluctuating Temperatures

September’s varied temperatures across France mean that layering is key. Start with a base of light, breathable fabrics and add layers such as sweaters or cardigans that can be easily removed as the day warms. A lightweight waterproof jacket or a trench coat is also a good idea for unexpected showers.

Recommendations for Both Dry and Rainy Days

Dry Days: For sunnier days, especially in the south or central parts of France, wear comfortable, breathable clothing like cotton shirts, dresses, and loose trousers. Don’t forget a hat and sunglasses for protection against the still-potent sun.

Rainy Days: On wetter days, especially common in the north and west, opt for waterproof outerwear. Consider waterproof shoes or boots to keep your feet dry, and carry an umbrella.

Special Regional Considerations

In the Mountains (Alps, Pyrenees, Massif Central): If you’re planning to visit higher altitudes, bring warm layers, including fleece or wool sweaters and a windproof jacket. The weather can change rapidly in mountainous areas, so be prepared for colder conditions.

Mediterranean Coast: Evenings can still be warm, so light, airy clothing is comfortable, but have a shawl or light jacket for when the temperature drops at night. The sun can be strong, so a sunhat and sunscreen are important.

Northern and Central France: The climate is more temperate, so mid-layers like long-sleeve tops and light sweaters are versatile for day-to-night temperature variations.

Western France: Given its oceanic climate, always be ready for a breeze or sudden shower with a lightweight scarf and a waterproof layer.
