Effect of wind speed on COVID-19 spread

Editor's Note

This study by researchers at Stony Brook University in New York finds that low wind speeds and warm stale air are associated with a higher incidence of contracting COVID-19 virus when people socialize outside.

Overall, the analysis showed that days with temperatures ranging from 61º to 82º F and wind speeds less than 5 MPH had significantly increased COVID-19 incidence, compared to similar days with an average wind speed of more than 5 MPH.

The researchers noted that the findings suggest that individuals socializing outdoors may not be completely safe and should remain vigilant, especially on days of reduced wind speeds during which airborne particles may be less likely to disperse.
