San Francisco North Beach features the neighbourhood's characteristic street trees of linden, introduced ornamental species, and the surrounding Telegraph Hill vegetation as the main pollen sources. The San Francisco Bay position means onshore winds can periodically disperse pollen, while the mild California Mediterranean climate advances the season and mugwort extends into September throughout this historic Italian-American San Francisco neighbourhood.

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

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 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.
