How to connect?

Westchester's Miami-Dade County Florida setting features live oak, melaleuca, and royal palm as the main tree pollen sources alongside subtropical vegetation, with exposure varying between the residential areas and the more built-up commercial corridors along Bird Road. The flat Miami-Dade landscape allows pollen to disperse widely, while the subtropical climate supports year-round vegetation contributing continuous pollen production throughout this west Miami suburban community.

When is pollen season in Westchester?
Westchester's Los Angeles suburban setting in Los Angeles County produces a season opening in January with olive and coastal sage before grass from surrounding Los Angeles County land peaks through March and April. Mugwort extends exposure into September, while the proximity to Los Angeles International Airport means a distinctive urban edge environment and the Pacific marine layer can periodically suppress pollen dispersal throughout the season.
How often is the Westchester pollen forecast updated?

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

Does pollen in Westchester 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 Westchester 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 Westchester, 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.
