What this means for you

Symptoms are likely even with treatment, and asthma can be triggered. Stay indoors with the windows closed where you can, avoid drying laundry outside, and keep reliever medication to hand.

How pollen levels are scored

Thresholds differ by plant, because the amount of pollen it takes to provoke symptoms differs by plant. A count of 20 is a moderate grass day and a very high ragweed one.

How these figures are produced

These counts come from the Copernicus atmospheric monitoring service, which models pollen concentrations on a grid across Europe, sampled at the coordinates of Les Pennes-Mirabeau. They are modelled values rather than grains counted at a pollen trap in the town, so neighbouring localities in the same grid cell will show similar figures, and a tree in flower on your street can matter more than the number here. Treat them as a regional indication. They are not medical advice: if symptoms are severe or persistent, speak to a doctor or pharmacist.
