Mission's parks and the Rio Grande corridor feature palm, mesquite, and introduced ash as the main tree pollen sources, with exposure varying between these green areas and the more built-up city centre. Surrounding South Texas brush country and agricultural land contribute seasonal grass and crop pollen, while the flat, open Rio Grande Valley landscape allows pollen to disperse readily across the area.

Which pollen types are currently active in Mission?

On 25 June 2026, Grass is the dominant pollen source in Mission. hazel, cypress, and willow are not currently active.

When is pollen season in Mission?
Mission's subtropical setting in the Rio Grande Valley produces a near year-round pollen season, with palm, mesquite, and introduced ash contributing through winter and spring. Grass pollen peaks through spring and early summer, while Gulf breezes from the nearby coast can periodically disperse pollen. The flat, open South Texas coastal landscape allows pollen from surrounding brush country and agricultural land to move readily across the city.
How often is the Mission pollen forecast updated?

The Mission pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Does pollen in Mission 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 Mission 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 Mission, 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.
