high temperatures all year with lots of rain
Tropical region.
Explanation:
Since the question was posted under Geopgraphy, I'm assuming that you want the region where high temperatures with lots of rain lasts all year.
It'll be in the tropical region / trophics. These are the regions that lie near the equator (between the Tropic of Cancer & Tropic of Capricon). They get the maximum amount of sunlight / the sun's rays (the Earth bulges about here because it's in the middle..the Earth is ellipsoidal in shape) & hence have high temperatures. Also, rainfall is quite prominent here. Some countries that lie in this region are: South India, Sri Lanka, Brazil, Thailand, Peru etc.
