What’s in the air in Cape Coral right now

The pollen model for Cape Coral currently tracks 3 active species — Ragweed (UPI 5/5), Elm (UPI 2/5), Grasses (UPI 2/5). Ragweed is the strongest source right now.

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.

Elm is a tree pollen source. Elm releases pollen in late winter and early spring, and some species pollinate again in fall.

Grasses is a grass pollen source. Grass is the most widespread pollen allergen in the country, typically peaking from late spring through midsummer — and lawn mowing stirs it up even outside the peak.

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 Cape Coral it has roughly 86 days left to run. Weed pollen doesn't stop on a calendar date — it stops when a hard frost kills the plants, and Cape Coral's average first frost falls around January 13.

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.
