Local Environmental Conditions
Built-up land makes up around 47% of the area near the heart of Heist-op-den-Berg, with a good deal of woodland and some open grassland. Oak heads the list of allergenic trees nearby, ahead of alder and birch. Grasses and weeds such as pigweed and plantain round out the local mix. Oak is unusually common here compared with most other locations, making it a particularly important local pollen source.
The pollen year starts in late winter, when alder flowers. Tree pollen peaks in late spring, when the weather warms to around 15°C and oak and birch are in full flower. Grass pollen follows, peaking in early summer and easing off by late summer. Pigweed and plantain bring a final peak from midsummer into mid-fall. The oak period in late spring is usually the most intense time of year here.

How often is the Heist-op-den-Berg pollen forecast updated?
The Heist-op-den-Berg pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Heist-op-den-Berg 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 Heist-op-den-Berg 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 Heist-op-den-Berg, 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.

Understanding the Scale
The 0–100 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
