Ha Giang's Climate
Ha Giang, at Vietnam's northernmost tip, has a mountainous subtropical monsoon climate that varies sharply with altitude. The rainy season runs from May to September, bringing heavy downpours and a real risk of flash floods and landslides along its famous mountain passes, while winter from November to February turns cold and foggy, with occasional frost on the high karst plateau around Dong Van and Meo Vac as temperatures fall below 5°C. Average temperatures range from about 15-28°C, peaking near 33°C in the lower valleys in summer.
