Vire pollen forecast - today, tomorrow and the week ahead

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

On 21 July 2026, pollen conditions in Vire 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 Vire. grass are also present but at lower levels. birch, hazel, cypress, willow, and alder are not currently active.

Vire opens its pollen year with hazel and alder appearing from late January, before birch and oak becomes dominant in the following weeks, before grass from pasture takes the season into summer, before the oceanic climate brings a quieter autumn.

The Vire 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 Vire, 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.
