How to connect?

Houma's parks, including Southdown Plantation and the Terrebonne Bayou corridor, feature oak, cypress, and magnolia as the main tree pollen sources, with exposure varying between these green areas and the more built-up city centre. Surrounding Louisiana coastal wetlands and marsh contribute substantial grass and reed pollen, while the flat, low-lying landscape and Gulf Coast position allow pollen to disperse readily across the area.

How often is the Houma pollen forecast updated?

Does pollen in Houma 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 Houma 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 Houma, 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.
