Newark's parks in California and the Mowry Slough corridor feature oak, eucalyptus, and introduced trees as the main pollen sources, with exposure varying between these green areas and the more built-up city centre. Surrounding East Bay hills and the San Francisco Bay shoreline contribute substantial grass and tree pollen, while prevailing westerly winds carry marine air that can periodically disperse pollen across the area.

How often is the Newark pollen forecast updated?
The Newark pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Newark 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 Newark 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 Newark, 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.
