About pollen in Frisco
Tree pollen is running high in Frisco today, with grass and weed levels adding to the mix at a more moderate pace. Anyone sensitive to tree pollen should expect noticeable symptoms outdoors, while grass and weed exposure is likely to cause milder irritation for most people. Overall, today counts as a tougher day for allergy sufferers, so it may be worth limiting extended time outside if you tend to react strongly. Looking ahead, tree pollen is expected to ease significantly over the next couple of days before ticking back up toward the end of the five-day stretch, and grass and weed levels are set to follow a similar dip-and-rebound pattern. This lines up with the seasonal shift happening now, as we move away from summer growth and into the heart of ragweed season, which is typically the main driver of fall allergies in North Texas. Late-season tree pollen from species like cedar elm and juniper can also contribute this time of year, so some lingering tree-related symptoms are not unusual even as temperatures cool.
