I like more the spring. In the winter here in my country it only rains when it's winter, and it's too hot in summer (it's almost +30º every day). Spring is a nice midle between this 2.
I prefer dry season, The sun is a lot more cheerful and when it rains in our place it gets flooded and i would have hard time going out to go to work i could be more productive. Since we have airconditioning to keep us cool rather than if it is raining there is nothing we can do.
