Nan is one of the northern provinces. Winters are quite dry and very warm. Temperatures rise until April, which is very hot with the average daily maximum at 37.0°C. The monsoon season runs from late April through October, with heavy rain and somewhat cooler temperatures during the day, although nights remain warm.HistoryFor centuries Nan was an independent kingdom but, due to its remoteness, had few connections to the other kingdoms. The first kingdom around the city Mueang Pua (also known as Varanagara) was created in the late 13th century. Its rulers, the Phukha dynasty, were related to the founders of Vientiane, however it became associated with the Sukhothai kingdom as it was easier to reach from the south than from the east or west. In the 14th century the capital was moved to its present location at Nan.
