On 17 July 2026, pollen conditions in Galena will be similar to today, with grass at low levels

According to the five-day outlook, ambrosia and grass pollen levels will increase later in the week.

On 16 July 2026, Grass is the dominant pollen source in Galena. ambrosia, artemisia, birch, cypress, oak, willow, and alder are not currently active.

Galena Historic District tracks Galena's broader pollen pattern, with maple and elm appearing from March with oak taking the lead through April. Grass follows, peaking through May and June, while ragweed extends the season into September. A humid continental climate drives a sharp spring tree peak and an equally distinct late-summer ragweed run, consistent with the wider Galena area.

The Galena 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 Galena, 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.
