The forecast from researchers is grim: Warm weather alone will not control the virus in America or abroad. But all the evidence available suggests weather plays a role with coronavirus transmission, but only a small one. In New York City, weather could reduce the rate of infections by a quarter during the hottest months. The weather effect helps push down the infection rate below the critical threshold where infections will decrease, but only in the hottest parts of the country. It’s not fully understood how warm weather controls the spread of the virus.
