Plains: The Central region mostly consists of alluvial plains whose dirt is deposited by the Ping , Wang, Yom and Nan rivers. The 2 major plains are the plains in the north of the region (mostly undulating plains) and the plains in the south of the region (or the Chao Phraya plain).
Influences on Climate: The Central region's climate is influenced by the southwest monsoon winds and sea breezes. The mountains of the north and the northern part of the Central region reduce the northeast monsoon winds' influence.
Temperature: The annual average temperature is 28 C, the average highest temperature being 33 C, and the average lowest temperature being 20 C, thus resulting in a low temperature range, about 13 C.
Rainfall: The average annual rainfall in the Central region is between 1000 mm to 1200 mm.. The province with the most average annual rainfall is Nakhorn Nayok (2100 mm.) and the least is Kampaeng Phet (987.7 mm.).
Seasons: The Central region has 3 seasons, the rainy season, from June to October, when the southwest monsoon winds and depression storms exert their influence, winter, from November to January, when the northeast monsoon winds exert their reduced influence and thus is not as cold as the winter of the North or Northeast , and summer, from February to May, which is less hot than the summer of the North or Northeast due to the  influence of the ocean and the trade winds from the ocean between February and April.
