Local Environmental Conditions
This location in Harcourt North is surrounded mainly by open grassland, with a good deal of woodland. Close to running water, riverside trees such as willow contribute to what is in the air. Allergenic trees nearby include willow. Grasses are a major source, with plantain adding to the weed pollen load.
Willow leads the season in early spring, as temperatures climb to around 10°C, and tree pollen reaches its peak. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into early fall. Plantain brings a final peak from mid-spring into early fall. Summer is the wettest time of year, and heavy showers can bring short breaks in pollen. By early winter, pollen levels are low again.

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 Harcourt North 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 Harcourt North, 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.
