If I had to choose between a humid tropical climate and a humid continental climate, I would definitely choose a humid tropical temperature due to the fact I prefer hot and humid summers, and mild winters. Furthermore, this kind of climate tends to be located at or near coastal locations, which is an aspect that I found crucial when deciding where to live. I need to be surrounded by beaches and sea, it is more appealing to me in order to enjoy life outside doing many activities according to these kind of weather, such as surfing. So that, If I had to pick a place with these characterisitics I would live in Sydney, in the New South Wales state of Australia.
