The area of the modern township was known to the Dutch as Lonkjouw,[1] alternatively spelled Liangkiau,[2] Long-kiau,[3] Longkiau, Loncjou, Lonckjau, Lonckiau, Lonkiauw, Lonckjouw, and Lonckquiouw in early records.
The Qing viceroy Shen Baozhen noted the equitable climate during his 1875 inspection of Taiwan Island, with the area's crops staying "green and prosperous" year-round.
After the Rover Incident, wherein shipwrecked American sailors were massacred by the locals, Charles Le Gendre, the US consul at Amoy (Xiamen), visited the area.
He ordered attacks against the still restive tribes and began a building program in the southern half of the island which included the fortified lighthouse at Eluanbi.
He memorialized on behalf of building a new city in Longkiau (which he gave the more propitious Chinese name "Hengchun") to accommodate and protect foreign sailors.
It usually has neither a cool winter nor an extremely hot summer, with average monthly mean temperatures ranging between 21 and 28 degrees Celsius.
Hengchun's spring-like climate is very much dictated by its location surrounded by the ocean, resulting in a noticeably smaller difference between the day and night temperatures than most other townships of Pingtung.
Hengchun is usually cooler than other townships in the county during daytime and warmer than others during the night, especially during the winter months, when daily lows usually hovers around 18–20 degrees Celsius at Hengchun and around 15–18 at Pingtung city, while daily highs usually hovers around 24–26 degrees Celsius at the township and 25–28 at Pingtung City.
Temperatures dips below 15 degrees Celsius on average once every 3 years, mostly on early mornings of January when Taiwan is affected by a cold front.
[14] The township comprises 17 villages: Chengbei, Chengnan, Chengxi, Daguang, Dehe, Eluan, Jiahu, Kending, Longshui, Nanwan, Renshou, Shanhai, Shanjiao, Shuiquan, Sigou, Tougou and Wangsha.
The peak season of tourism in Hengchun usually lasts from April to late October when daytime temperatures are usually hot, while the off season lasts from November to March of the following year, with the exception of the week of the Chinese New Year holiday which usually takes place during late January or February, when large amount of tourist from around the whole country, mostly from Northern Taiwan travels to Hengchun and Kenting for the peninsula's warm weather.
