About pollen in Cary
Weed pollen is the main story in Cary today, running high and likely to cause noticeable symptoms for those who are sensitive to it. Grass is contributing at a low level, while tree pollen is nearly absent, so any irritation you feel is almost certainly coming from weeds rather than trees or grass. Looking ahead, weed pollen is expected to stay high for the next few days before easing toward the end of the period, so anyone bothered by it should plan for a few more uncomfortable days before conditions calm down. Grass will remain low and largely steady, and tree pollen should stay quiet throughout. This pattern fits the season well: early fall in the Piedmont is ragweed country, with weed pollen typically peaking now, long after the oaks, pines, and other spring-blooming trees around Cary have finished releasing pollen for the year.

- When driving the car, close your windows and turn the air conditioning system to recirculation mode.
