New Orleans Pollen Report
New Orleans barely gets a winter — and neither do its plants. Live oaks and pines drive the late-winter and spring seasons, grasses pollinate for most of the year, ragweed carries the fall, and the city's famous humidity keeps mold spores active in essentially every month. It's one of the longest allergy calendars in the country.

What drives allergies in New Orleans
Trees: live oak and pine (January – April)
Live oak (Quercus virginiana) — the city's signature tree — is the biggest spring allergen, with pine, pecan, and hackberry contributing from January onward.
Grasses: Bermuda and Bahia (March – November)
Warm-season grasses pollinate for most of the year in the subtropical climate.
Weeds: ragweed (August – November)
Ragweed (Ambrosia) fills the fall, overlapping with grass season and post-storm mold.
Mold: the year-round constant
Gulf humidity and frequent rain keep Alternaria and Cladosporium active in every month, with major spikes after tropical storms and flooding.

Frequently asked questions
What is the pollen count in New Orleans today?

Is the pollen count high in New Orleans right now?

When is allergy season in New Orleans?
Effectively year-round: trees January–April, grasses March–November, ragweed August–November, and mold in every humid month.
Why do allergies flare after storms in New Orleans?
Flooding and rain feed mold growth indoors and out — post-storm weeks often bring some of the highest mold spore counts of the year.
Is pollen still bad in New Orleans in the fall?
Yes. Ragweed runs through October in New Orleans, and the warm, wet Gulf climate keeps mold spores high through fall and winter. New Orleans rarely gets a true pollen break between seasons.
