Crater Lake National Park is a subalpine fir and mountain hemlock forest around the caldera rim. High elevation delays pollen until July. The season is brief but conifer pollen can be visible on the lake's deep blue surface.

How often is the Crater Lake pollen forecast updated?

Does pollen in Crater Lake 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 Crater Lake 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 Crater Lake, 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.
