Elevated ozone levels and ragweed pollen are forecast to lower air quality across parts of Houston from Oct. 21 through Oct. 31, 2026.
The city often experiences ozone spikes during warm periods, and ragweed pollen is a common seasonal allergen. Together, the heightened ozone and abundant pollen can worsen respiratory conditions for residents.
