How to connect?

Mira Mesa HS's Baseball Diamond sits in the Mira Mesa suburban landscape of northern San Diego, with introduced olive, eucalyptus, and coastal sage scrub as the main surrounding pollen sources. Surrounding canyon and mesa chaparral vegetation contribute substantial grass and scrub pollen, while the mild Southern California Mediterranean climate advances the season and the canyon setting can concentrate pollen under certain conditions throughout.

How often is the San Diego pollen forecast updated?

Does pollen in San Diego 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 Diego 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 Diego, 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.
