How to connect?

Long Beach Poly HS's Baseball Diamond is set in the Long Beach urban landscape of Los Angeles County, with introduced olive, eucalyptus, and palm as the main surrounding pollen sources alongside urban coastal vegetation. The Pacific Ocean coastal proximity means onshore marine winds frequently disperse pollen, while the mild Southern California Mediterranean climate advances the season and mugwort extends exposure into September throughout.

How often is the Long Beach pollen forecast updated?

Does pollen in Long 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 Long 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 Long 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.
