Local Environmental Conditions
Most of the area around the heart of São José dos Campos is built-up land, with a good deal of woodland. Locally, the surrounding woods make trees an important source; street trees, parks and lawns are the main sources in the built-up parts. Roadside verges and patches of open ground provide further room for grasses and weeds.
Tree pollen comes first, peaking in early spring. Grasses take over in mid-spring, with temperatures around 20°C, and their pollen lingers into mid-fall. Weeds on open ground add a smaller late peak from early summer into early fall. In warm, humid weather from early summer into mid-fall, mold spores add to the mix, especially after rain.

Are pollen levels in São José dos Campos 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 São José dos Campos, 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.
