Sheep Ranch's Oregon coast setting features coastal grasses, shore pine, and gorse as the main pollen sources across the dramatic clifftop course, with exposure varying between the exposed Pacific Ocean-facing holes and the more sheltered inland sections. The Pacific Ocean position means strong onshore winds frequently disperse pollen, while the very wet Oregon coast climate provides very frequent rainfall interruptions throughout the long spring and summer season.

Does pollen in Coos Bay come from nearby or far away?

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 Coos Bay 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 Coos Bay, 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.
