On the NSW mid-north coast, pollen season extends from August to January, with tree pollen from coastal eucalypts and casuarina opening in late winter and grass pollen from coastal pasture and roadside verges peaking October to December. The mild, humid coastal climate here can stretch grass pollen exposure slightly later into summer than inland areas, particularly after rain.

The Port Macquarie pollen forecast is updated four times daily. See the timestamp below for the most recent update.

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.

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 Port Macquarie, 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.
