On 25 June 2026, Grass is the dominant pollen source in Saint-Quentin. cypress are also present but at lower levels. willow, alder, birch, and hazel are not currently active.

Saint-Quentin's Somme headwaters and canal setting channels airflows across the historic industrial city. Hazel and alder open from January before birch peaks through April, with oak and ash following through May. Grass and crop pollen from surrounding Picardy farmland peaks strongly through June and July, while frequent Atlantic rainfall provides regular interruptions and the flat landscape allows pollen to disperse widely.

The Saint-Quentin 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 Saint-Quentin, 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.
