Local Environmental Conditions
Oak, birch, and oak dominate the tree canopy in Kalmar, mostly concentrated away from the paved city core. The open landscape near the Kalmar Strait facing Öland contributes substantial grass and crop pollen, especially where farmland borders the built-up area. For most residents of Kalmar, distance from parks and green belts matters more for pollen exposure than any local industry.
In Kalmar, the pollen calendar begins as early as January with alder and hazel, giving way to an intense birch peak across April and May. Once birch fades, grass pollen sustains elevated counts through most of the early summer. Kalmar's location relative to the Kalmar Strait facing Öland means daily pollen readings can swing with changes in wind direction. Surrounding oak-dominated woodland and farmland extend the tail of the season into August.

How often is the Kalmar pollen forecast updated?

Does pollen in Kalmar 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 Kalmar 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 Kalmar, 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 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
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. |
