Local Environmental Conditions
Around 97% of the area near this location in Green Valley is open grassland. Grasses are also a significant pollen source here. Roadside verges and patches of open ground provide further room for grasses and weeds. Pollen also travels on the wind, so vegetation in the wider surroundings adds to local levels as well.
Grasses take over in late spring, with temperatures around 20°C, and their pollen lingers into early fall. A smaller weed peak follows from early summer into early fall. Winter is the wettest time of year, and heavy showers can bring short breaks in pollen. Dry, sunny and breezy weather raises levels within each period, and steady rain brings them down.

Does pollen in Green Valley come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Green Valley 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 Green Valley, 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.
