About pollen in Nampa

Weed pollen is the main driver of today's conditions in Nampa, and it is running high. Anyone with sensitivities to ragweed or related late-season weeds should expect symptoms to be fairly noticeable, especially during outdoor activity in the afternoon. Looking ahead, weed pollen is expected to remain high for the next couple of days before easing slightly to a more moderate level through the rest of the week. This pattern fits the season well: early October is typically the tail end of ragweed and weed pollen activity in the region, as fall takes hold and tree pollen from species like cottonwood, elm, and maple remains dormant until spring. For now, weeds are the one to watch, with some gradual relief likely as the week progresses.
