How to connect?

Set on a rugged stretch of the northern Oregon coast, Cannon Beach's landscape is defined by Sitka spruce and shore pine alongside coastal salal and dune grass, the main contributors to seasonal pollen exposure. Seasonal timing here follows the broader regional pattern typical of this part of the country. As with most of the region, counts tend to build gradually rather than spike overnight.

How often is the Cannon Beach pollen forecast updated?

Does pollen in Cannon Beach 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 Cannon Beach 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 Cannon Beach, 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.
