Local Environmental Conditions
This site in West Pennant Hills is surrounded mainly by woodland, which covers around 77% of the nearby area, with some built-up land. Olive heads the list of allergenic trees nearby, ahead of maple. Beyond the trees, grasses matter a great deal, and plantain and pigweed are the main weed sources.
Olive and maple lead the season in early spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Grasses take over in mid-spring and keep pollen in the air into mid-fall. Plantain and pigweed flower through much of the warmer half of the year. In warm, humid weather from midsummer into early fall, mold spores add to the mix, especially after rain.

Are pollen levels in West Pennant Hills 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 West Pennant Hills, 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.
