Local Environmental Conditions
The area around the heart of Alkmaar is densely built up, with some woodland. Allergenic trees nearby include maple, alder and hazel. Grass pollen is plentiful, while plantain and mugwort lead among the weeds. Mugwort is unusually common here compared with most other locations, making it a particularly important local pollen source.
First to flower are alder and hazel, in late winter. Tree pollen peaks in mid-spring, when the weather warms to around 10°C and maple is in full flower. Grasses take over in early summer and keep pollen in the air into late summer. Plantain and mugwort bring the strongest peak of the year from late spring into early fall.

How often is the Alkmaar pollen forecast updated?
The Alkmaar pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Alkmaar 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 Alkmaar 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 Alkmaar, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
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. |
