Montebello's San Gabriel Valley setting features olive, Mexican fan palm, and pepper tree as the main tree pollen sources, with exposure varying between the limited greener residential areas and the more built-up commercial and industrial corridors along Whittier Boulevard. The Rio Hondo River corridor provides the most significant local green space, while the flat, densely developed suburban landscape means limited local vegetation variation and Santa Ana winds can periodically transport pollen from the San Gabriel Mountains.

Does pollen in Montebello 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 Montebello 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 Montebello, 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.
