On 16 July 2026, Grass is the dominant pollen source in Alcobendas. cypress, willow, alder, artemisia, birch, and hazel are not currently active.

Alcobendas' pollen season opens in February with hazel and olive before oak and ash peak through April. Grass from surrounding Castilian Meseta farmland peaks strongly through May and June. The dry continental climate concentrates pollen during spring, while the Jarama valley channels airflows and the intense early summer heat ends the season abruptly by July.

The Alcobendas 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 Alcobendas, 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.
