About pollen in Surprise
Weed pollen is the main driver of today's high overall count in Surprise, and sensitive individuals should expect noticeable symptoms if spending extended time outdoors. Grass pollen is also present at a moderate level, adding to the irritation for those who react to multiple pollen types. Tree pollen, by contrast, is quiet and not a concern right now. Looking ahead, weed pollen is expected to remain high and may climb even further over the next several days, while grass pollen should hold steady at a moderate level. This pattern fits the season: late September is peak time for ragweed and other desert weeds in the Southwest, which is why weed pollen is dominating right now. Tree pollen is not a factor this time of year, since local trees such as mesquite, olive, and palo verde typically release their pollen in spring rather than fall.
