Corona del Mar HS's Baseball Diamond is set in the Corona del Mar coastal suburban landscape of Newport Beach in Orange County, with introduced olive, eucalyptus, and coastal sage scrub as the main surrounding pollen sources. The Pacific Ocean coastal proximity means onshore marine winds frequently disperse pollen along this exposed coastal setting, while the mild Southern California climate advances the season and mugwort extends into September throughout.

Does pollen in Newport 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 Newport 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 Newport 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.
