La Prairie pollen forecast - today, tomorrow and the week ahead

On 30 August 2026, overall pollen levels in La Prairie are high. Ambrosia is the main contributor to airborne pollen, while grass remain at lower levels

On 31 August 2026, pollen conditions in La Prairie will be different from today, with ambrosia at high levels and grass continuing to decline

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

On 30 August 2026, Ambrosia is the dominant pollen source in La Prairie. grass are also present but at lower levels. artemisia and cypress are not currently active.

At La Prairie, the woodland's oak and birch trees become the main pollen source by mid-spring, climbing steadily through spring to a peak in April or May. The water-adjacent hazel and willow are early risers, usually peaking sometime between late winter and the end of March. Late spring brings rising grass pollen that crests in June, and ragweed later takes the lead from mid-August through October.

The La Prairie 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 La Prairie, 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.
