Local Environmental Conditions
The area around the heart of Portaferry is a patchwork of open water, open grassland and woodland. Grasses matter a great deal here, and plantain and pigweed are the main weed sources. Roadside verges and patches of open ground provide further room for grasses and weeds. Wind carries pollen over long distances, so the wider landscape also shapes what arrives here.
Flowering trees bring the first pollen of the year in mid-spring. Grasses take over in midsummer, with temperatures around 15°C, and their pollen lingers into early fall. Later, plantain and pigweed keep weed pollen in the air from late spring into early fall. By early winter, as temperatures fall to around 5°C, pollen levels are low again.

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