Can windy days shield you from COVID-19?

Low wind speeds and stale air are associated with as much as 45% higher incidence of contracting COVID-19 when people socialize outside, researchers say.

Low wind speeds and stale air are associated with a higher incidence of contracting COVID-19 when people socialize outside, perhaps as much as 45% more, a new study shows.

While it may not be the season for beach going and barbecues, people continue to work and gather outside in many settings. Is that cause for concern in these latest stages of the pandemic, and new variants?

Not necessarily, the researchers say.

The findings, published in BMC Infectious Diseases , are based on COVID-19 incidence in Suffolk County, NY, from March 16, 2020, to December 31, 2020, from public health data of more than 96,000 cases.

Researchers used these data in combination with daily reports by the National Oceanic and Atmospheric Administration on the region’s average wind speed and maximal daily temperatures.

“The issue is really about an increased danger of infection spread in the presence of stale air as opposed to indoor versus outdoor settings,” explains Sean Clouston, associate professor in the program in public health, and the department of family, population, and preventive medicine at the Renaissance School of Medicine at Stony Brook University. “The findings imply we are all safer when air flow is more significant.”

Clouston and colleagues developed a statistical modeling program that determined from the public health data and weather reports that warmer days with little wind when people socialized outside resulted in significantly more COVID-19 transmission.

Their overall analysis revealed that days with temperatures ranging from 16 to 28 degrees Celsisus (approximately 61 to 82 degrees Fahrenheit) where wind speed was less than 8.85 kilometers per hour (approximately 5 mph) had significantly increased COVID-19 incidence compared to similar days with an average wind speed of greater than 8.85 kilometers per hour.
