Tomorrow Festival takes place at the Tomorrowland festival grounds in Boom on the Schelde River plain in the Antwerp province, where oak, birch, and linden are the main tree pollen sources across this large open festival landscape. The flat Flemish polder surroundings allow pollen to disperse widely, while birch peaks through April and May, grass from the extensive open festival grounds peaks strongly through June and July, and mugwort extends into September throughout this iconic Belgian electronic music festival.

Does pollen in Boom 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 Boom 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 Boom, 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.
