Novato's North Bay California setting produces a season opening in January with oak and olive before grass from surrounding Marin County land peaks through April and May. Mugwort extends exposure into September, while the bay proximity moderates temperatures and the Marin hills concentrate pollen under certain wind conditions. The Petaluma Gap channels marine breezes that can rapidly disperse pollen across this North Bay suburban city throughout.

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 Novato, 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.
