About Pollen in Toulouse
Toulouse’s spring allergy season (February-May) is dominated by Cypress and Plane pollen; Cypress (Cupressus) prolific in residential gardens; London Plane (Platanus x acerifolia) widespread along the Canal du Midi and Grand Rond. Ash (Fraxinus) and Oak (Quercus) contribute significantly from the Forêt de Bouconne. Summer (May-July) sees high Grass (Poaceae) pollen levels, originating from the Prairie des Filtres and Garonne riverbanks.
The Autan wind carries pollen from the Lauragais plains; it creates high concentrations in the city center. Autumn and winter see elevated Mould (Alternaria, Cladosporium) spore counts, from damp leaf litter along the Garonne and Jardin des Plantes.
