Kalmar pollen forecast - today, tomorrow and the week ahead

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

On 17 July 2026, pollen conditions in Kalmar will be similar to today, with grass at medium levels, cypress at low levels

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

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

In Kalmar, the pollen calendar begins as early as January with alder and hazel, giving way to an intense birch peak across April and May. Once birch fades, grass pollen sustains elevated counts through most of the early summer. Kalmar's location relative to the Kalmar Strait facing Öland means daily pollen readings can swing with changes in wind direction. Surrounding oak-dominated woodland and farmland extend the tail of the season into August.

The Kalmar 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 Kalmar, 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.
