Castellón de la Plana's coastal parks and the Rambla de la Viuda corridor feature orange, olive, and pine as the main tree pollen sources, with exposure varying between these green areas and the more built-up city centre. Surrounding Valencian citrus and vegetable farmland contribute substantial grass and crop pollen, while the Mediterranean coastal position means sea breezes can periodically disperse pollen.

Are pollen levels in Castellón de la Plana 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 Castellón de la Plana, 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.
