Local Environmental Conditions
Residents in Paisley Renfrew dealing with hay fever usually point to rowan and alder as the culprits, particularly in spring near parks and gardens. The nearby local common land adds further grass and tree pollen exposure, particularly under southwesterly winds. Overall exposure follows the broader regional trend, moderated somewhat by the town's parks and gardens.
Locals in Paisley Renfrew usually notice rowan first, with alder not far behind it. After that, grass pollen carries the season from May through to September, with June and July normally the toughest stretch. Rowan pollen typically runs from May to June, while alder follows on from January to April. Not a bad idea to stock up on antihistamines before it all kicks off.

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. |
