Allergy season is getting longer in Northwest Arkansas and around the nation amid climate change, according to a new Climate Central analysis.
❄️ The big picture: Plants' freeze-free growing season lengthened from 1970 to 2025 in nearly 90% of the 198 cities analyzed in the climate research group's latest report.
- The extended time between the last and first freeze helped determine the length of allergy seasons around the country.
🔎 Zoom in: In NWA, shifting trends added about 15 days to our annual allergy season, according to the data.
Yes, but: The season has decreased by 15 days in Tulsa, Oklahoma, about 110 miles west.
What they're saying: Climate Central vice president for science Kristy Dahl said longer allergy seasons were "a clear signal of a warming world, driven by carbon pollution."
- "As temperatures rise, freeze-free seasons are stretching in every region of the country, giving plants weeks of extra time to grow and release pollen."
- "For millions of Americans, that means earlier, longer, and often more intense allergy seasons that can take a real toll on health and daily life."
🌡️ What's next: NWA's warm stretch is expected to continue this week, after a dip on Wednesday, with highs in the next few days pushing toward 80.
