Pollen season generally ends at different times depending on the type of pollen and your location:
- Tree pollen season typically ends by late spring or early summer, around May to June. In some milder climates, tree pollen may continue into June or July.
- Grass pollen season usually wraps up by mid-summer, around July or August, though it can last into early fall in some regions.
- Weed pollen season, especially from ragweed, tends to last the longest, ending around the first hard frost, which is usually late October to early November. In warmer areas, it can persist well into November.
Overall, the traditional peak pollen season tends to slow down by September, marking the end of the main hay fever season for many people, although some weed pollens may still cause symptoms into October and November.
So, if you're looking for a general end to pollen season, it depends on which type of pollen affects you most and where you live, but for most places, the season is mostly over by late summer to early fall, with some lingering weed pollen possibly extending into late fall.
