Pollen and allergies in San Juan del Río
Pollen figures for San Juan del Río are temporarily unavailable. They will return as soon as the Copernicus model publishes again.
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 San Juan del Río. 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.
