Local Environmental Conditions
Most of the area around this location in Val Verde is open grassland, with a good deal of scrubland. The damp ground beside a watercourse nearby supports trees such as willow, adding to local pollen. Of the trees nearby, oak and willow are the ones that matter most for allergies. Grass pollen is plentiful, while pigweed and mugwort lead among the weeds.
Oak and willow lead the season in mid-spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Grasses take over in late spring, with temperatures around 20°C, and their pollen lingers into early fall. The season closes with pigweed and mugwort from early summer into early fall. Winter is the wettest time of year, and heavy showers can bring short breaks in pollen.

Does pollen in Val Verde 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 Val Verde 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 Val Verde, 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.
