About pollen in Largo
Weed pollen is the main concern in Largo today, running high enough to cause noticeable symptoms for those who are sensitive. Tree and grass pollen remain low in comparison, so most of the day's discomfort, if any, is likely to trace back to weeds rather than trees or grasses. Looking ahead, weed pollen should gradually ease over the next several days, moving from high down toward quiet levels by the end of the stretch, while tree and grass pollen are expected to stay low throughout. This pattern fits the season: autumn in Florida is typically ragweed territory, with weed pollen taking center stage while oak, pine, and other common regional trees stay largely dormant until their usual spring peak.
