Mérida's Guadiana River floodplain and the surrounding Extremaduran dehesa landscape feature oak, olive, and eucalyptus as the main tree pollen sources, with the cork oak and holm oak dehesa being a particularly significant and distinctive regional source. Surrounding farmland extends grass pollen, while the hot, dry continental climate concentrates pollen dispersal firmly during the spring season.

How often is the Mérida pollen forecast updated?

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

Does pollen in Mérida 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 Mérida 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 Mérida, 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.
