Local Environmental Conditions
This part of New Orleans is heavily wooded, with a good deal of open grassland. Lawns and planted trees in a nearby park add to local grass and tree pollen. Trees are an important local pollen source, given how much woodland surrounds the area. There is plenty of grass pollen here too.
Tree pollen comes first, peaking in early spring. Grass pollen follows, peaking in mid-spring and easing off by mid-fall. A smaller weed peak follows from early summer into early fall. Mold spores join in through spring, when damp, warm spells let them thrive. Actual levels on any given day depend on the weather, with dry, breezy days the worst and wet days the mildest.

How often is the New Orleans pollen forecast updated?

Does pollen in New Orleans 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 New Orleans 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 New Orleans, 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.
