Clay's Onondaga County New York suburban setting features oak, maple, and birch as the main tree pollen sources, with exposure varying between the greener residential areas around Oneida Lake and the more built-up commercial corridors along Route 31. The Oneida Lake shoreline creates temperature-modifying effects, while the numerous Clay wetlands and Cicero Swamp corridor contribute distinctive wetland vegetation pollen and the flat Oneida Lake plain allows grass pollen to disperse widely throughout.

Grass from surrounding New York farmland peaks through June and July before mugwort and nettle extend exposure into September. The Oneida Lake proximity moderates temperatures locally, while the continental climate produces a well-defined seasonal progression throughout.
How often is the Clay pollen forecast updated?

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

Does pollen in Clay 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 Clay 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 Clay, 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.
