Local Environmental Conditions
Most of the area around the heart of Rochdale is built-up land, with a good deal of woodland. Close to running water, riverside trees such as willow, poplar and alder contribute to what is in the air. Of the trees nearby, oak, alder and birch are the ones that matter most for allergies. Grasses are a major source, with plantain and mugwort adding to the weed pollen load.
The pollen year starts in late winter, when alder flowers. Tree pollen peaks in late spring, when the weather warms to around 10°C and oak and birch are in full flower. Grasses take over in midsummer and keep pollen in the air into late summer. Later, plantain and mugwort keep weed pollen in the air from late spring into late summer.

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