Newport News' pollen season opens with oak and pine from late January, followed by sweet gum through February and March. Grass pollen peaks through May and June, with ragweed extending the season into October. The James River estuary and Chesapeake Bay position mean coastal breezes can periodically disperse pollen, while surrounding Virginia coastal plain woodland contributes substantial tree and grass pollen throughout the extended season.

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.

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 News, 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.
