Climate chart - Nha Trang (Vietnam)
In Nha Trang the climate is tropical, with a relatively cool winter from December to February and a hot, muggy summer from May to September. As for the rains, there is a dry season from January to April and a rainy season from September to December due to the northeast monsoon. Instead, as in the rest of the central coast, the summer monsoon brings little rain.
The city is located in the south-central part of the coast of Vietnam, in the province of Khanh Hoa, at 12 degrees north latitude. All around are mountains that exceed 1,000 meters (3,300 feet), reaching 1,850 meters (6,070 ft) to the west (in Hon Ba nature reserve).
A short distance from the coast we find some small islands including Vĩnh Nguyên.
The closest cities are Ninh Hòa to the north and Cam Ranh to the south, both on the coast. Instead, about 80 km (50 mi) to the southwest, in the interior, we find Da Lat.
The winter, from December to February, is warm, in fact the January average is 24.5 °C (76 °F). Unlike in central-northern Vietnam, there are no cold air irruptions here, however, there can be days with minimum temperatures of 17/18 °C (63/64 °F) and maximum temperatures of 23/24 °C (73/75 °F).
From April to August, humid heat prevails, with winds from the sea and quite rare rains. Sometimes it can be very hot, although less than in central-northern Vietnam. However, sometimes the temperature can reach 36/37 °C (97/99 °F).
Here are the average temperatures.
