Local Environmental Conditions
Built-up land makes up around 35% of the area near this part of Wellington, with a good deal of woodland and open grassland. Close to a watercourse, riverside vegetation contributes to what is in the air. So much tree cover makes trees an important source of pollen locally. Grass pollen is a substantial part of the local mix as well.
With warm weather all year, between about 20°C and 30°C, pollen is present in most months rather than in one short season. The drier stretch around January to March usually brings the most pollen. During the rainy season, frequent heavy downpours wash much of the pollen out of the air. Mold spores are in the air most of the year too, rising after rain.

How often is the Wellington pollen forecast updated?

Does pollen in Wellington 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 Wellington 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 Wellington, 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.
