Pollen Count & Forecast for Montpellier

Montpellier’s spring allergy season (February-May) is dominated by Cypress and Plane pollen; Cypress (Cupressus) widespread along the Promenade du Peyrou; Plane (Platanus) common along the Esplanade Charles-de-Gaulle. Olive (Olea europaea) contributes from orchards near the city periphery. Summer (May-July) sees high Grass (Poaceae) pollen levels, originating from the Lez River banks and Pellitory-of-the-wall (Parietaria) from stone walls in the Écusson district.

Mistral winds carry pollen from the Cévennes mountains and the garrigue scrubland. Autumn and winter see elevated Mould (Alternaria, Cladosporium) spore counts, from decomposing organic matter in the Jardin des Plantes and damp Mediterranean environments.
