DeForest pollen forecast - today, tomorrow and the week ahead

On 30 August 2026, overall pollen levels in DeForest are high. Artemisia is the main contributor to airborne pollen, while grass and ambrosia remain at lower levels

On 31 August 2026, pollen conditions in DeForest will be different from today, with grass at high levels, ambrosia at high levels and artemisia continuing to decline

According to the five-day outlook, artemisia, grass, and ambrosia pollen levels are expected to gradually decrease, suggesting improving conditions later in the week.

On 30 August 2026, Artemisia is the dominant pollen source in DeForest. grass and ambrosia are also present but at lower levels. cypress are not currently active.

In DeForest, hazel and willow by the water are typically first out of the gate, climbing steadily from late winter into March. Oak and birch in the woods pick up where the earlier species leave off, reaching maximum intensity across the April-May window. Through late spring, grass pollen climbs steadily toward its June peak, before ragweed takes over as the dominant allergen from mid-August through October.

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

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 DeForest, 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.
