Petroşani pollen forecast - today, tomorrow and the week ahead

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

On 17 July 2026, pollen conditions in Petroşani will be different from today, with grass at medium levels

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

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

hazel and alder opens the pollen season in Petroşani as early as February, with oak and hornbeam building through the following weeks before grass carries exposure into early summer; the overall window runs February through September. ragweed builds through late summer into autumn here, one of the region's heaviest such seasons. Conditions in the enclosed Jiu valley basin in the Carpathians shape how quickly pollen disperses once the peak has passed.

The Petroşani 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 Petroşani, 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.
