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

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

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

Pollen season in Agen gets underway in January and February with hazel and alder, then peaks with oak and plane across April and May, before grass from vineyard and farmland then dominates into early summer, a rhythm shaped by the area's oceanic-continental climate.

The Agen 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 Agen, 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.
