The fully exposed position means Pacific winds very frequently disperse pollen across the hilltop, while the fog belt marine layer frequently suppresses pollen production and the surrounding scrub contributes distinctive native pollen throughout.

San Francisco Twin Peaks features the exposed hilltop grassland and coastal scrub of the Twin Peaks summit as the main pollen sources in this elevated San Francisco setting. The fully exposed position means Pacific winds very frequently disperse pollen across the hilltop, while the fog belt location means the marine layer frequently suppresses pollen production and the surrounding scrub contributes distinctive native pollen throughout this dramatic San Francisco hilltop.
How often is the San Francisco pollen forecast updated?

The San Francisco pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Does pollen in San Francisco 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 San Francisco 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 San Francisco, 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.
