Local Environmental Conditions
The area around this location in Mount Clarence is mostly woodland, with some open water and built-up land. Lawns and planted trees in a nearby park add to local grass and tree pollen. The surrounding woodland makes trees an important local pollen source. Grasses are a major source, with plantain adding to the weed pollen load.
Tree pollen comes first, peaking in mid-spring. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into mid-fall. Plantain flowers through much of the warmer half of the year. Rain is heaviest in winter, often giving short breaks from high pollen levels. Weather shapes each of these periods: dry, windy spells drive levels up, and showers wash pollen out of the air.

Does pollen in Mount Clarence 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 Mount Clarence 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 Mount Clarence, 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.
