Local Environmental Conditions
Just over 45% of the area near Roxborough Park is built-up land, with a good deal of open grassland and some woodland. Along a stream or river nearby, trees such as poplar grow in the damper ground and add their own pollen. The leading allergenic tree nearby is oak, with maple close behind. Grasses and weeds such as mugwort and pigweed round out the local mix.
Tree pollen peaks in late spring, when the weather warms to around 10°C and oak and maple are in full flower. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into early fall. Mugwort and pigweed bring a final peak from midsummer into early fall. Rain is heaviest in spring, often giving short breaks from high pollen levels.

Are pollen levels in Roxborough Park based on measurements or forecasts?

Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Roxborough Park, 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.
