Why do we need four seasons: Spring, Summer, Fall, and Winter. In general, Spring is considered from March, April, and May. Another season comes from June, July, and August. One of the best season (at least for me) is the September, October, and November. Finally (and the worst) is December, January, and February.
I grew up in an island called GUAM. They do have a season but basically, has only two: Dry and Rainy Season.
It was great! The majority of the houses has swimming pool. During the weekend, we spend a lot of times at the beach and barbecue. In other words, there was only one season: Summer.
As Japanese, I really don't know which seasons we're adapted for. Truthfully speaking, Fall would be nice for me.
