Appenzell pollen forecast - today, tomorrow and the week ahead

On 16 July 2026, overall pollen levels in Appenzell are moderate. Grass is the main contributor to airborne pollen, while cypress remain at lower levels

On 17 July 2026, pollen conditions in Appenzell will be different from today, with grass continuing to decline

According to the five-day outlook, grass pollen levels are expected to gradually decrease, while cypress pollen will increase, suggesting mixed conditions later in the week.

On 16 July 2026, Grass is the dominant pollen source in Appenzell. cypress are also present but at lower levels. willow, alder, artemisia, birch, and hazel are not currently active.

From January, Appenzell's pollen season begins with hazel and alder, followed by a birch peak through April. Oak and ash pollen build afterward, and grass takes over across June and July. Air tends to move along these valleys, occasionally bunching up pollen on still days, while nearby cropland and forested foothills keep the season going strong.

The Appenzell 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 Appenzell, 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.
