Phetchabun is a town (thesaban mueang) in Thailand, capital of Phetchabun Province. It covers the tambon Nai Mueang of the Phetchabun District, along the Pa Sak River. As of 2005, it had a population of 23,823. Phetchabun lies north of Bangkok.
From historical evidence, it is believed that Phetchabun was established by two kingdoms, the Sukhothai Kingdom and the Ayutthaya Period of King Narai. Initially the province was called "Phe-cha-buth" as "Phuenchapura", which means 'town that grows plenty of crops', as the province is very fertile.
The Pa Sak River runs through the east side of Phetchabun from north to south. The town lies in a valley; the two ranges of the Phetchabun Mountains rise to both the east and west.
Phetchabun has a tropical savanna climate (Köppen climate classification Aw). Winters are dry and very warm. Temperatures rise until April, which is very hot with the average daily maximum at 37.2°C. The monsoon season runs from late April through early October, with heavy rain and somewhat cooler temperatures during the day, with nights remaining warm.
The main road through the city is Route 21, from Lom Sak to the south through Phetchabun to Chai Badan and Saraburi.
Phetchabun is served by Phetchabun Airport, 29km (18miles) to the north.[1]
