How to connect?

Curitiba's urban green network, anchored by Barigui Park and the Iguaçu River corridor, features Araucaria pine, eucalyptus, and native Atlantic Forest species as the main tree pollen sources, with exposure varying between these green areas and the more built-up city centre. Surrounding Paraná highland woodland and farmland contribute substantial tree and grass pollen, with the subtropical highland climate producing a more defined pollen season than in lower-altitude Brazilian cities.

When is pollen season in Curitiba?
Curitiba's pollen season is most pronounced during the dry season from May to September, when eucalyptus, pine, and native Atlantic Forest species release pollen and grass exposure increases across the city. The subtropical highland climate means the season is more defined than in tropical Brazilian cities, with the wet summer months from November to March bringing frequent rainfall that suppresses dispersal across the city.
How often is the Curitiba pollen forecast updated?

The Curitiba pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Does pollen in Curitiba come from nearby or far away?

Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.

Are pollen levels in Curitiba based on measurements or forecasts?

Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.

Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Curitiba, modern forecasts combine recent measurements, weather data, and information about local vegetation.

This allows us to estimate pollen levels for today and the coming days, not just report the past.
