Toul pollen forecast - today, tomorrow and the week ahead

On 20 July 2026, overall pollen levels in Toul are low. Grass is the main contributor to airborne pollen

On 21 July 2026, pollen conditions in Toul will be different from today, with cypress at low levels, grass at low levels, artemisia at low levels

According to the five-day outlook, cypress and grass pollen levels are expected to gradually decrease, while artemisia pollen will increase, suggesting mixed conditions later in the week.

On 20 July 2026, Grass is the dominant pollen source in Toul. cypress, willow, alder, artemisia, birch, and hazel are not currently active.

Toul sees its pollen season begin in late winter, with hazel and alder the first to appear, and progresses through oak and hornbeam from April into May, before the season closes with grass and cereal through early summer, a pattern typical of the continental climate here.

The Toul 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 Toul, 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.
