Paris, France has a temperate oceanic climate with mild, wet winters and warm, humid summers. Spring and fall are transition seasons with variable weather.
Pollen season in Paris typically starts in late February with tree pollen, followed by grass pollen in May and weed pollen in August. Ragweed pollen can be particularly problematic.
Paris's location in the Paris Basin and proximity to the sea can affect pollen count, with occasional spikes during dry, windy weather. However, overall pollen levels are relatively low compared to other European cities.
When pollen counts are high, we suggest doing these things to help with allergies, especially on windy days when pollen is flying around.
