Local Environmental Conditions
The area around the heart of St Agnes Cornwall is a mix of open grassland and woodland, plus some built-up land. Among allergenic trees nearby, willow leads, followed by maple and ash. Beyond the trees, grasses matter a great deal, and plantain and pigweed are the main weed sources. Grasses along roadsides, verges and open ground also add to the overall pollen load.
Willow, maple and ash lead the season in late winter, as temperatures climb to around 10°C, and tree pollen reaches its peak. Grasses take over in early summer, with temperatures around 15°C, and their pollen lingers into early fall. Plantain and pigweed bring a final peak from late spring into late summer. Mold spores join in from midsummer into early fall, when damp, warm spells let them thrive.

Are pollen levels in St Agnes Cornwall 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 St Agnes Cornwall, 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.

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. |
