Coronavirus. : Yes, according to previous knowledge, most virus including coronavirus likely will not survive hotter climates. I would expect or hope this will die down in summer time. Nevertheless, this is new coronavirus, let's wait and see. I also think that with strong human intervention, the virus may reduce or be eliminated before summer.

We don't know: The common human coronaviruses usually do die down during the summer. However, we can only hope that will happen with COVID 19 - we don't know for sure.
