Midcity Baton Rouge follows Baton Rouge's established pollen calendar, beginning with oak and pine from January with cedar following close behind through February. Grass pollen then peaks through March and April, and a long ragweed tail runs well into October. Mild winters along the Gulf mean the pollen season starts earlier and runs longer than further north, a defining feature of the local season.

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 Baton Rouge, 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.
