Local Environmental Conditions
Most of the area around this site in Portarlington is open water, with some wetland and open grassland. With a watercourse close by, riverside vegetation contributes to the local mix. With much of the immediate area made up of open water, local pollen production is limited, though pollen can still drift in from surrounding land. Grasses, pigweed and plantain growing in the surroundings are the main non-tree sources of pollen.
Grass pollen follows, peaking in early summer and easing off by early fall. The season closes with pigweed and plantain from early summer into early fall. Rain is heaviest in spring, 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.

Are pollen levels in Portarlington 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 Portarlington, 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.
