What’s in the air in Franklin right now

The pollen model for Franklin currently tracks one active species: Ragweed (UPI 3/5).

The 5-day forecast shows weed pollen holding roughly steady.

Ragweed is a weed pollen source. A single ragweed plant can release about a billion pollen grains, and it dominates the late-summer-to-first-frost allergy season across most of the US.

The tree, grass, and weed rows above roll these species into three groups, but knowing the exact species helps: if allergy testing showed what you react to, you can check whether your trigger is actually the one flying today.

Ragweed is the driver this time of year, and in Franklin it has roughly 13 days left to run. Weed pollen doesn't stop on a calendar date — it stops when a hard frost kills the plants, and Franklin's average first frost falls around October 31.

That is why the same ragweed season is weeks shorter in the northern states than in the South: identical plants, different frost dates. A single ragweed plant can release around a billion pollen grains, and they travel hundreds of miles on the wind, so a low local count doesn't guarantee a quiet day.
