Warm weather is not a direct factor in eliminating the SARS-CoV-2 virus. The high temperatures required to effectively denature the viral proteins and kill the virus (typically sixty degrees Celsius and above) are rarely reached in natural, daily environments.

The major component of SARS-CoV-2 is protein, and protein may denature in high temperatures. Yet, what is "high temperature"? It may have a wide range. Sometimes, the interaction of the peptide bond may be affected at 41 Celcius. However, they will not denature completely until 101 Celcius (Chemistry Explained, 2020) for some proteins. And according to the research of NIH, if we want to kill coronavirus with high temperature, we need to expose it at least 3 minutes when the surrounding temperature is 75 Celcius or 5 minutes when the temperature is 65 Celcius, and 20 minutes when the temperature is 60 Celcius and above (Abraham et al., 2020). It is rare (even impossible) to reach 60 Celcius degrees in our daily life.
