Local Environmental Conditions
Around 33% of the area near the center of Portlethen is built-up land, with a good deal of open grassland and some farmland. Willow, birch and maple are among the allergenic trees nearby. Grasses and weeds such as plantain and pigweed round out the local mix. Street trees, private gardens and mown lawns add to local pollen in the more built-up surroundings.
Willow, birch and maple lead the season in mid-spring, as temperatures climb to around 5°C, and tree pollen reaches its peak. Grass pollen follows, peaking in midsummer and easing off by early fall. The season closes with plantain and pigweed from late spring into early fall. Rain is heaviest in winter, often giving short breaks from high pollen levels.

How often is the Portlethen pollen forecast updated?
The Portlethen pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Portlethen 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 Portlethen 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 Portlethen, 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. |
