Local Environmental Conditions
Most of the area around this location in Mérida is built-up land, with some woodland. With this much woodland around, trees are an important local pollen source. Grasses also feature strongly, alongside plantain and pigweed among the weeds. In the immediate area, planted trees and mown lawns are the main sources in the built-up parts.
Tree pollen comes first, peaking in early spring. Grasses take over in late spring and keep pollen in the air into early fall. Plantain and pigweed flower through much of the warmer half of the year. Fall is the wettest time of year, and heavy showers can bring short breaks in pollen. By midwinter, as temperatures fall to around 5°C, pollen levels are low again.

Does pollen in Mérida 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 Mérida 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 Mérida, 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.
