Paris in September Holidays end and the city fills up again. Days feel summery and evenings are properly cool. On Heritage Days, the third weekend of September, normally closed buildings open, though some need advance booking. Rainy days start to creep up.
Neither hot nor cold: 22°C by day and 13°C after dark. Spending hours on foot was easy. Showers came now and then, about 8 rain days in all, and most of the month stayed dry. Counts moved moderately between years: 4 in 2007, 15 in 2024.
About 1 day a month still climbed past 30°C, the ones where you looked for shade. September 2023 averaged 26.0°C by day, 4.3°C above the 20-year mean. Rain came often but gently, about 6 mm on a typical wet day.
