Chumphon (Thai: ชุมพร, in Thai pronounced as /t͡ɕʰūm.pʰɔ̄ːn/) is a town (thesaban mueang) in southern Thailand, capital of the Chumphon Province and Mueang Chumphon District. The city is about 463 kilometers (288 miles) from Bangkok. As of 2018 it had a population of around 33,600. The town covers the commune (tambon) Tha Taphao completely and parts of tambons Bang Mak, Wang Phai, Na Thung, Tak Daet, and Khun Krathing. Its main economic activity is agriculture.
Chumphon volunteers fought invading Japanese during World War II. Chumphon became a rail hub for Imperial Japan. It was a station on the Southern Line and connected to the short-lived Kra Isthmus Railway.[2]
Chumphon lies just inland from the west coast of the Gulf of Thailand. To the west are the northern hills of the Phuket Range, a subrange of the Tenasserim Hills. These hills reach 400m (1,300feet) in the area near Chumphon. There are also many smaller peaks in the area in the range of 100m (300feet) to 200m (700feet) high.
Chumphon has a tropical monsoon climate (Köppen climate classification Am) just falling short of a tropical rainforest climate (Köppen Af). Temperatures are hot throughout the year. The period from December to April has relatively less rainfall than from May to November, when rainfall can be very heavy, particularly in October and November.
Nok Air and Thai AirAsia operate multiple daily flights between Bangkok (Don Mueang, DMK) and Chumphon Airport. The airport is a hub and regional gateway providing connecting services to Chumphon city and high speed ferry services to the islands of the Gulf of Thailand including Ko Tao and Ko Samui.
