Local Environmental Conditions
Around 47% of the area near the center of Capelle aan den IJssel is woodland, with a good deal of built-up land and some open grassland. Common allergenic trees nearby include maple, hazel and alder. Grasses also feature strongly, alongside plantain and pigweed among the weeds. Compared with most places, pellitory is especially widespread here, which makes it one of the key local allergens.
Tree pollen peaks in mid-spring, when the weather warms to around 10°C and maple is in full flower. Grass pollen follows, peaking in early summer and easing off by late summer. Later, plantain and pigweed keep weed pollen in the air from late spring into early fall. The pellitory period in late spring is usually the most intense time of year here.

How often is the Capelle aan den IJssel pollen forecast updated?
The Capelle aan den IJssel pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Capelle aan den IJssel 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 Capelle aan den IJssel 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 Capelle aan den IJssel, 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.
