Flers pollen forecast - today, tomorrow and the week ahead

On 20 July 2026, overall pollen levels in Flers are low. Artemisia is the main contributor to airborne pollen, while grass remain at lower levels

On 21 July 2026, pollen conditions in Flers will be similar to today, with artemisia at low levels, grass at low levels

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

On 20 July 2026, Artemisia is the dominant pollen source in Flers. grass are also present but at lower levels. willow, alder, birch, hazel, and cypress are not currently active.

Flers begins its pollen season in deep winter, as hazel and alder start to release, before birch and oak becomes dominant in the following weeks, before the season closes with grass from pasture through early summer, a pattern typical of the oceanic climate here.

The Flers 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 Flers, 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.
