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 North York based on measurements or forecasts?

Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in North York, 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.
