About pollen in Upper West Side

Weed pollen is the only category with any real presence on the Upper West Side today, and it remains on the low side. Tree pollen is quiet, with nothing being released at the moment, so most sensitive noses should find the air fairly calm today, with only mild effects for those who react strongly to weeds like ragweed. Looking ahead, this pattern is expected to hold steady over the next several days, with weed pollen staying at that same low, low-grade level and tree pollen remaining absent. This fits the season well: local trees such as oak, linden, honeylocust, pyrus, and elm are long past their spring release and won't be active again until next year, while weeds like ragweed are winding down as autumn progresses. Overall, conditions should stay mild and manageable through the week.
