Local Environmental Conditions
Around 46% of the area near this part of Hordern Vale is woodland, with a good deal of open water. Close to a stream or river, riverside vegetation contributes to what is in the air. Trees are an important local pollen source, given how much woodland surrounds the area. Beyond the trees, grasses matter a great deal, and pigweed is the main weed source.
Tree pollen comes first, peaking in early spring. Grasses take over in early summer, with temperatures around 15°C, and their pollen lingers into late summer. Pigweed brings a final peak from early summer into early fall. In warm, humid weather from midsummer into early fall, mold spores add to the mix, especially after rain.

Are pollen levels in Hordern Vale based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.

This allows us to estimate pollen levels for today and the coming days, not just report the past.
