They stuck a bunch of guinea pigs into a box, one box at 41F, a 2nd at 68F, and a third at 86F.
The box with 41F had the highest transmission rate. The box at 68F and 86F had lower transmission rates, even 0% transmission rate in the presence of 80% humidity.

No such experiment exists for COVID19 yet. But because COVID19 continues to exponentially grow in the southern hemisphere (Australia in particular), there doesn't seem to be a relationship between temperature, humidity, and COVID19 like there is with the flu.
