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

The pollen calendar in Riga starts with hazel and alder, shifts to local tree and grass through the spring weeks, and grass extends the season into early summer, spanning February through August overall. Ragweed adds a late-season tail in areas closest to farmland and disturbed ground.

The Riga 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 Riga, 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.
