According to the five-day outlook, cypress pollen levels are expected to gradually decrease, while willow pollen will increase, suggesting mixed conditions later in the week.

On 16 July 2026, Cypress is the dominant pollen source in Franca. willow and amaranthaceae are not currently active.

The driest stretch in Franca, May to September, brings the heaviest pollen exposure as eucalyptus and coffee plantation vegetation pollen circulates without rain to interrupt it, before wetter weather resumes and washes much of it from the air.

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

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.

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 Franca, 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.
