Local Environmental Conditions
Kilkenny's River Nore setting features oak, ash, and beech as the main tree pollen sources, with exposure varying between riverside greenery and the built-up medieval city centre. Surrounding farmland extends grass pollen through summer.
Kilkenny sits along the River Nore amid Ireland's fertile southeastern farmland, giving it a moderate pollen season, with alder and hazel producing a fairly typical spring bloom, while surrounding pastureland sustains Ireland's characteristically long grass pollen season, and mugwort and nettle along riverbanks and city walls add a gentle late-summer trickle.

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

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. |
