Local Environmental Conditions
Tree pollen in Lampeter comes mostly from oak and ash, with parks and mature gardens standing in contrast to the more built-up centre. Fields and hedgerows just outside town push grass pollen counts up noticeably once the area's changeable Atlantic weather set in. The relatively open, low-lying landscape lets pollen disperse readily across the area through the season.
Ask anyone with allergies in Lampeter and they'll tell you it's oak and ash that cause the trouble. Grass then takes over from May right through September, peaking around June and July for most people. Oak tends to release pollen between April and May, before ash takes over, usually March to May. Something to plan around if pollen usually gets to you.

How often is the Lampeter pollen forecast updated?

Does pollen in Lampeter 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 Lampeter 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 Lampeter, 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. |
