Metairie pollen forecast - today, tomorrow and the week ahead

On 16 July 2026, overall pollen levels in Metairie are low. Ambrosia is the main contributor to airborne pollen, while grass remain at lower levels

On 17 July 2026, pollen conditions in Metairie will be similar to today, with ambrosia at low levels, grass at low levels

According to the five-day outlook, ambrosia and grass pollen levels will increase later in the week.

On 16 July 2026, Ambrosia is the dominant pollen source in Metairie. grass are also present but at lower levels. artemisia, birch, cypress, oak, willow, and alder are not currently active.

Metairie's pollen season opens with oak and pine from late January in the mild Gulf Coast climate. Grass pollen follows through March and April, with ragweed extending the season into October. The flat, low-lying suburban setting and surrounding Louisiana coastal wetlands and the Lake Pontchartrain shoreline contribute substantial grass and reed pollen, while the warm, humid climate supports one of the longer pollen seasons of any US city.

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

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.

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 Metairie, 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.
