Paris Weather in September

September weather in Paris

September feels mild rather than summery, with afternoons around 22°C and cooler evenings near 11°C. Rain falls on about ten days, so a shower can interrupt a walk, but it rarely rules out a whole day. You'll get pleasant conditions for strolling along the Seine, exploring the Marais or visiting the Musée d'Orsay.

The days are getting shorter, and clouds are common. Save outdoor plans for dry spells, and use a rainy afternoon for the covered passages near the Grands Boulevards. The weather's still comfortable for sightseeing, but don't count on long, hot days by the river.

Events and crowds

The European Heritage Days usually take place in September. They open doors to historic buildings that aren't normally open to visitors, including sites around central Paris. Popular spots can draw long queues, so choose one or two rather than trying to see everything.

If you hate crowds, skip the busiest sights on heritage weekend and wander around Canal Saint-Martin instead. Paris is busy again after the quieter August holiday period, as locals return to work and school. It's not the peak summer crush, but central areas still feel lively. Prices tend to ease from August, though they remain higher than in quieter winter months.

Make the most of the month

September is a good time for a full day on foot, with a café stop when rain rolls in. For a local treat, duck into a boulangerie near Rue Montorgueil for a still-warm baguette, then take it to the nearby Jardin des Tuileries if the weather holds.

Travelling with kids? The Jardin des Plantes has room to roam, plus the Grande Galerie de l'Évolution for a rainy-day visit. Check the European Heritage Days programme for access details; some sites require a timed reservation, while others admit visitors in queues.
