Why Late Summer Brings Allergy Misery
If your allergy symptoms seem to spike just as summer fades into fall, ragweed pollen is likely to blame. Every year, millions of Americans deal with sneezing, itchy eyes, and congestion during ragweed season, which typically runs from late August through October.
But why is this time of year so challenging and how long can you expect symptoms to last? Let’s take a closer look.
Ragweed’s Peak Season
Ragweed is a hardy weed that thrives in warm weather. It begins releasing pollen as summer winds down, usually in mid-to-late August.
The season then continues until the first hard frost, which kills off the plant. In many areas of the U.S., this means ragweed season lasts until late October or early November.
The worst pollen counts usually occur in September, which is why so many people suddenly feel like their allergies are out of control this month.
Where is Ragweed Found?
Ragweed grows in 46 states, especially in the Midwest, South, and along rural roadsides or open fields. But even if it doesn’t grow near you, its pollen can travel hundreds of miles on the wind, so moving to another region rarely solves the problem.
When Are Symptoms Worst During the Day?
If you’ve noticed that your allergies flare at certain times, you’re not alone. Ragweed pollen levels are typically:
- Highest in the morning (around 5 a.m.–10 a.m.)
- Higher on dry, windy days
- Lower after heavy rain
This means taking extra precautions in the morning and on breezy days can help reduce symptoms.
Preparing Ahead of Time
One of the most effective ways to manage ragweed allergies is to start your allergy medications before the season begins. For many people, this means beginning daily antihistamines or nasal sprays in early or mid-August, so that your body is ready when pollen counts rise.
If you wait until symptoms are severe, it’s often harder to get them under control.
Long-Term Solutions
While medications can provide short-term relief, many people benefit from allergy shots (immunotherapy) or sublingual allergy drops. These treatments gradually train your immune system to stop overreacting to ragweed pollen, providing lasting relief over time.
Bottom Line: Ragweed Season Runs Late Summer Through Fall
If your symptoms started suddenly in late August or early September, ragweed is likely the reason. Expect pollen counts to remain high through September and taper off after the first frost in October.
The good news? With the right prevention strategies and treatment plan, you can reduce symptoms and breathe easier throughout the season.
