Lake Zurich pollen forecast - today, tomorrow and the week ahead

On 9 August 2026, overall pollen levels in Lake Zurich are moderate. Ambrosia is the main contributor to airborne pollen, while artemisia remain at lower levels

On 10 August 2026, pollen conditions in Lake Zurich will be different from today, with grass at medium levels and ambrosia, artemisia increasing

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

On 9 August 2026, Ambrosia is the dominant pollen source in Lake Zurich. artemisia are also present but at lower levels. cypress and grass are not currently active.

Streamside willow and alder near the Fox River kick off the local pollen calendar, usually strongest in the weeks before spring fully arrives. The wooded areas near Van Patten Woods Forest Preserve then carry the tree pollen load into its sharpest phase, typically centered on April and May. Farther out toward the Des Plaines River and Grant Woods Forest Preserve, tree pollen tends to follow this same rough schedule.

The Lake Zurich 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 Lake Zurich, 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.
