Buenos Aires' tree-lined boulevards and green spaces, including Bosques de Palermo and the Río de la Plata waterfront, feature plane, poplar, and introduced ash as the main tree pollen sources, with counts varying between these greener areas and the more built-up city centre. Surrounding Pampas grassland and farmland add substantial grass and crop pollen throughout the Southern Hemisphere spring season.

How often is the Buenos Aires pollen forecast updated?

Does pollen in Buenos Aires 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 Buenos Aires 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 Buenos Aires, 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.
