Seasons Thailand has three. Expats lovingly refer to the seasons as hot (Nov-Feb), hot and wet (Jun-Oct) and damned hot (Mar-May). Where you plan to live could, of course, temper the "damned hot" to hot. The tourism authority likes to call the hot season the "cool or mild season".
If you really truly love rain, then Ranong is your Nirvana. The folks near the Ismuth of Kra got 6,699 mm in 1955. For those who are metrically challenged, that's 22' of rainfall.
If you prefer a dryer climate, you might want to look around Prachuap or the Korat Plateau area. Those regions average somewhere around 1,000 -1,200 mm or 3.3'-4' annually. As one might expect, river valleys and coastal regions are also prone to heavier rainfall. Details on Thailand's rainfall
