About pollen in Meridian

Weed pollen is the main concern in Meridian today, with levels running high enough to cause noticeable symptoms for those who are sensitive. Tree pollen is quiet, so any irritation you're feeling is almost certainly coming from weeds rather than trees. If you tend to react to ragweed or similar late-summer weeds, expect today to be a more uncomfortable day than usual, especially during outdoor activity in the afternoon. Looking ahead, weed pollen is expected to hold steady at these elevated levels through the next several days, so there's no relief in sight for the near term. This lines up with the season — mid-August is peak territory for ragweed and other weeds across the Treasure Valley, while tree pollen from local species like cottonwood, ash, and maple remains dormant until spring. If weeds typically affect you, this is a stretch where staying mindful of outdoor exposure can help you manage symptoms more comfortably.
