On 17 July 2026, pollen conditions in Joensuu will be different from today, with grass at medium levels, artemisia at low levels and cypress increasing

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

On 16 July 2026, Cypress is the dominant pollen source in Joensuu. grass, willow, alder, artemisia, birch, and hazel are not currently active.

Joensuu sees a short but intense pollen season from March to August, dominated by birch in late spring and followed by a grass peak into early summer. Calm, still spring days tend to let birch pollen linger longer than usual.

The Joensuu 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 Joensuu, 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.
