Local Environmental Conditions
The heart of Shannon is surrounded mainly by woodland, which covers around 89% of the nearby area. With a stream or river close by, riverside vegetation contributes to the local mix. Around here, the surrounding woods make trees an important source. Grasses along roadsides, verges and open ground also add to the overall pollen load.
Tree pollen comes first, peaking in early spring. Grass pollen follows, peaking in late spring and easing off by early fall. Rain is heaviest in winter, often giving short breaks from high pollen levels. Dry, sunny and breezy weather raises levels within each period, and steady rain brings them down.

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