Local Environmental Conditions
Just over 65% of the area near the heart of Sandstone is woodland, with some open grassland and built-up land. Close to a watercourse, riverside vegetation contributes to what is in the air. Common allergenic trees nearby include birch and maple. Grasses add a sizeable share of the local pollen.
Birch and maple lead the season in mid-spring, as temperatures climb to around 5°C, and tree pollen reaches its peak. Then come the grasses, strongest in early summer and fading by late summer. A smaller weed peak follows from early summer into early fall. Summer is the wettest time of year, and heavy showers can bring short breaks in pollen.

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