Local Environmental Conditions
Around 77% of the area near the center of Viladecáns is built-up land. Oak, olive and poplar are among the allergenic trees nearby. Grasses also feature strongly, alongside plantain and pigweed among the weeds. Compared with most places, olive is especially widespread here, which makes it one of the key local allergens.
Oak, olive and poplar 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 and keep pollen in the air into early fall. Plantain and pigweed flower through much of the warmer half of the year. The olive period in late spring is usually the most intense time of year here.

Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Viladecáns 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 Viladecáns, 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.
