Local Environmental Conditions
Open water and open grassland share the area around this part of Bonny Doon, plus some woodland. Of the trees nearby, oak and cypress are the ones that matter most for allergies. Grasses and weeds such as mugwort and plantain round out the local mix. Cypress is unusually common here compared with most other locations, making it a particularly important local pollen source.
The pollen year starts in early spring, when cypress flowers. Tree pollen peaks in late spring, when the weather warms to around 15°C and oak is in full flower. Grasses take over in midsummer and keep pollen in the air into early fall. Mugwort and plantain bring a final peak through summer. The cypress period in early spring is usually the most intense time of year here.

Are pollen levels in Bonny Doon 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 Bonny Doon, 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.
