Looking at countries with wide community spread[1] the spread is very clearly tied to cold weather (Europe, Korea, and Iran). This pattern is similar to other air transmitted viruses such as the Flu. Warmer countries seem to be resilient despite some having higher density and lower hygiene standards (e.g. India).
Given that the default assumption should be the COVID-19 will follow the flu pattern of diminishing rapidly in March up to barely any case in April [2]. This by no means try to diminish actions to be cautious, or the risk it imposes. However, if you are asked to put money on a certain direction, betting on warming up weather reducing the R value of the virus enough to stop it is what I would do.
