Local Environmental Conditions
Most of the area around this location in Rome is built-up land, with a good deal of woodland. Oak is the most prominent allergenic tree nearby, with olive also present. Grass pollen is plentiful, while pellitory and pigweed lead among the weeds. Compared with most places, pellitory is especially widespread here, which makes it one of the key local allergens.
Oak and olive lead the season in mid-spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Grasses take over in late spring and keep pollen in the air into early fall. The most intense period comes from late winter into late fall, when pellitory and pigweed are in flower. Rain is heaviest in fall, often giving short breaks from high pollen levels.

Does pollen in Rome 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 Rome 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 Rome, 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.
