Local Environmental Conditions
Wexford's estuary setting on the Slaney River features oak, ash, and coastal grassland as the main pollen sources, with exposure varying between the harbourside town centre and the surrounding farmland and coastline.
Wexford sits at the mouth of the River Slaney on Ireland's southeastern coast, giving it a mild, sea-tempered pollen season, with coastal and riverine air softening the spring tree bloom, while surrounding farmland sustains Ireland's characteristically long grass pollen season, and mugwort and nettle along the quays and field edges provide a gentle late-summer trickle.

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