Local Environmental Conditions
Around 46% of the area near this part of The Hills Shire Council is built-up land, with a good deal of woodland. Lawns and planted trees in a nearby park add to local grass and tree pollen. The key allergenic tree nearby is olive. Olive is unusually common here compared with most other locations, making it a particularly important local pollen source.
Olive leads the season in early spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Then come the grasses, strongest in mid-spring and fading by early fall. Later, pigweed and plantain keep weed pollen in the air from early summer into early fall. The olive period in early spring is usually the most intense time of year here.

Are pollen levels in The Hills Shire Council 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 The Hills Shire Council, 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.
