Saint Cloud pollen forecast - today, tomorrow and the week ahead

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

On 31 August 2026, pollen conditions in Saint Cloud will be different from today, with ambrosia at high levels and grass, artemisia increasing

According to the five-day outlook, grass, ambrosia, and artemisia 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 Saint Cloud. grass and artemisia are also present but at lower levels. cypress are not currently active.

In Saint Cloud, the water-adjacent hazel and willow are early risers, climbing steadily from late winter into March. The woodland's oak and birch trees become the main pollen source by mid-spring, usually peaking from April into May. Grass pollen counts rise through late spring, reaching their peak around June, then yields to ragweed, the dominant late-summer and fall allergen through October.

The Saint Cloud 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 Cloud, 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.
