What this forecast doesn’t measure, and when to get help.
Google’s index covers tree, grass and weed pollen only, so there is no mold level for Baton Rouge on this page. The National Allergy Bureau publishes pollen and mold counts measured at its stations. Our guides cover common molds such as Alternaria, Cladosporium and Aspergillus.
The forecast doesn’t cover allergens indoors either: dust mites, cockroaches, mice, cats and dogs. Our guides explain each one, starting with dust mites and cats.
An estimated 10.9% of adults in the city of Baton Rouge have current asthma, according to the CDC’s PLACES estimate for 2023 (95% confidence interval: 9.7% to 12.3%). It is a statistical estimate from national survey data, not a count.
13 allergists enrolled in Medicare practice in the Baton Rouge area: 1.46 for every 100,000 people, more than the 1.22 across the US. The count doesn’t show how soon you can get an appointment. See the doctors listed in the Baton Rouge area, or how every state and metro compares.

The geography, climate and plants behind each season here, with a source for every fact.
Nearly 62 inches of rain and other precipitation falls at the airport in an average year, and the freeze-free season runs about 276 days.1 LSU AgCenter horticulturist Dan Gill wrote in 2014 that moderate to high pollen levels in Louisiana can stretch from March to November.2
Many shade trees, such as oak, maple, ash, pecan and birch, are wind-pollinated.2 The LSU AgCenter also flags waxleaf privet in spring for its profuse white flowers and pollen, even though bees and other insects usually pollinate it.3
In early May 2014, Gill noted that many cool-season grasses were still blooming and that some early warm-season grasses might be too.2 He singled out bermudagrass as a highly allergenic plant that flourishes in garden beds and lawns.2 Goldenrod and ragweed bloom at the same time in the fall.2
Answered from the values on this page.
No. The highest level in Baton Rouge today, Wednesday, November 4, is low (2 on the 0 to 5 index), led by ragweed. Weed pollen is low and tree pollen is very low.
According to Google’s model: Ragweed (low) and elm (very low). Plants Google doesn’t model, and mold, aren’t included.
Yes. Google’s forecast for tomorrow, Thursday, is moderate (3 on the 0 to 5 index), up from today’s low. Over the next four days, the highest forecast is moderate, on Thursday.
No. It’s Google’s modeled pollen index, from 0 (none) to 5 (very high), calculated for the location of central Baton Rouge. A pollen count is the number of pollen grains measured in a cubic meter of air at a counting station. How our pollen index works.
Twice a day. We fetch new values soon after midnight in Baton Rouge, so each day starts with its own values, and again after Google’s daily model run, usually by about 9:30 am CT. Each section shows when its values were retrieved.
Since October 14, 2026. The year in pollen above fills in as each day is recorded, and weeks before then show no data. Google doesn’t provide past values, so nothing earlier can be added.
