Łomża's Narew River valley and surrounding Podlaskie landscape feature oak, birch, and pine as the main tree pollen sources. Surrounding farmland and the Łomża Landscape Park woodland contribute substantial tree and grass pollen, while the continental Baltic climate produces a well-defined spring pollen season with birch being particularly significant across this historic city in northeastern Poland.

The cold continental Baltic climate means birch is particularly significant during the spring peak period.
How often is the Łomża pollen forecast updated?

Does pollen in Łomża come from nearby or far away?

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.

Are pollen levels in Łomża based on measurements or forecasts?

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 Łomża, 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.
