Jelgava pollen forecast - today, tomorrow and the week ahead

On 25 June 2026, overall pollen levels in Jelgava are high. Grass is the main contributor to airborne pollen, while cypress remain at lower levels

On 26 June 2026, pollen conditions in Jelgava will be similar to today, with cypress at medium levels, grass at high levels

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

On 25 June 2026, Grass is the dominant pollen source in Jelgava. cypress are also present but at lower levels. hazel, willow, alder, and birch are not currently active.

Jelgava's pollen season runs from February through August, opening with alder and hazel from February before birch peaks strongly through April and May. Grass pollen peaks through June and July. The Lielupe River valley channels airflows, while surrounding Latvian lowland farmland contributes substantial grass and crop pollen. The continental Baltic climate produces a well-defined seasonal progression with birch being particularly significant during spring.

The Jelgava 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 Jelgava, 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.
