Paris Summer Nights: What to Expect Temperature-Wise

During the summer months (June–August), the average nightly low in Paris hovers around 16°C (61°F).

However, nights can vary significantly. Heatwaves can keep temperatures in the low 20s°C (70s°F), while cool, rainy spells can drop them to 10–12°C (50–54°F). Urban heat island effects make the city center slightly warmer than outer arrondissements or parks like Bois de Boulogne.

Pack layers: a light jacket or sweater is essential for evenings, even in July.
