Preliminary results from the government lab experiments in the U.S. show that the coronavirus does not survive in high temperatures and high humidity and can get destroyed by sunlight. So summertime is less hospitable for the virus.
According to the study, the risk of transmission from surfaces outdoors is lower during daylight and under high temperatures as the sunlight destroys the virus quickly. This may be good news for pursuing outdoor activities. The DHS describes the results as preliminary and may eventually make their way into specific recommendations. So far the results of these tests have not yet been made public. In fact scientists had earlier predicted with the help of available data that warmer climates would be less hospitable to the spread of the virus.
