Local Environmental Conditions
Glendalough's glacial valley setting in the Wicklow Mountains features oak, birch, and heather moorland as the main pollen sources, with exposure varying between the wooded valley floor and the exposed upland slopes above.
Set within the Wicklow Mountains beside two glacial lakes, Glendalough experiences a cool, valley-shaded pollen season, with birch and hazel producing a moderately delayed spring bloom, while the surrounding upland bog and forest keep grass pollen lighter than in lowland Ireland, and scattered mugwort and nettle along trail edges provide only a minor late-summer trace.

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