In Guarda, Sequeira lies on the Beira interior plateau; local vegetation is dominated by oak and plane, and grass and coastal scrub pollen from the wider countryside pushes totals higher as spring turns to summer. Exposure differs meaningfully between the town centre and its greener edges, with the surrounding Guarda land contributing an additional, steadier layer of grass pollen through the warmer months.

How often is the Sequeira pollen forecast updated?
The Sequeira pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Sequeira 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 Sequeira 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 Sequeira, 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.
