Local Environmental Conditions
Local farmland and hedgerows nearby add meaningful grass pollen through late spring and summer, especially under the area's changeable Atlantic weather. On top of that, birch and pine are the two species driving most tree pollen in Oban, especially around parks and green corridors. Locals with allergies tend to plan around two peaks a year rather than one long stretch.
Ask anyone with allergies in Oban and they'll tell you it's birch and pine that cause the trouble. Then grass pollen takes the baton from May all the way to September, usually peaking in June and July — that's when most people really feel it. Expect birch pollen roughly from March to May, then pine carries on from April until June. Something to plan around if pollen usually gets to you.

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