Local Environmental Conditions
This location in Old Reynella is surrounded mainly by built-up land, with a good deal of woodland and some open grassland. Olive is the most prominent allergenic tree nearby, with ash also present. Grass pollen is significant here, and pigweed and plantain contribute weed pollen. Compared with most places, olive is especially widespread here, which makes it one of the key local allergens.
Tree pollen peaks in late spring, when the weather warms to around 15°C and olive and ash are in full flower. Grasses take over in late spring and keep pollen in the air into early fall. Pigweed and plantain bring a final peak from early summer into early fall. The olive period in late spring is usually the most intense time of year here.

Does pollen in Old Reynella 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 Old Reynella 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 Old Reynella, 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.
