AAFA highlights start of fall allergy season, offers tips for dealing with symptoms<\/em><\/p>\n

\n

Washington, D.C., September 4, 2025 \u2013 If you\u2019re sneezing this season, the reason could be a respiratory infection or weed pollen allergy. A review of pollen counts from cities across the country reveals a rise in levels of ragweed pollen<\/a> as well as other weed pollen.<\/p>\n

The Asthma and Allergy Foundation of America\u2019s (AAFA) 2025 Allergy Capitals\u2122 Report<\/a> notes that about 1 in 7 people in the U.S. are allergic to ragweed pollen. Weed pollen season (with ragweed being a primary offender) tends to start in August and may last 6 to 10 weeks, ending with the first frost. In most areas of the U.S., ragweed season generally peaks by mid-September, though other weeds may extend a few weeks longer.<\/p>\n

\u201cWe see weed pollen season start around this time every year,\u201d said Kenneth Mendez, president and CEO of AAFA. \u201cThe first fall frost generally stops the weeds from pollinating. But because climate change is making temperatures warmer, the first frost arrives much later. This means a longer, more intense period of symptoms for people allergic to ragweed and other weed pollen.\u201d<\/p>\n

In addition to ragweed, other common weeds contributing to fall pollen season include: burning bush, cocklebur, lamb\u2019s quarters, mugwort, pigweed, Russian thistle, sagebrush, and tumbleweed.<\/p>\n
