Deeba Masood, MD, an allergist and immunologist on the Northwestern Medication Medical Group in Vernon Hills, IL, tells Well being that finally, the size of a 12 months’s ragweed season relies on the temperature—it wants heat, however not too sizzling, temperatures to outlive. “These days, it appears to final three to 4 weeks longer, beginning the primary of August by means of mid-October,” she says, including specialists recommend local weather change as a contributing issue.
Mould—a fungus with seeds known as “spores” that journey by means of the air—is one other widespread reason for fall allergy symptoms, in line with Dr. Masood.

Dr. Moss says different sorts of weeds, corresponding to pigweed, marsh elder, and mugwort additionally plant their seeds by means of pollination within the fall months to allow them to reproduce within the following 12 months.
Relying on the place you reside, bushes and grass may also pollinate throughout fall.
