The southern climate is characterized by relatively constant temperatures, with a variation accompanied by the arrival of the monsoon in May. There are...

three distinguishable seasons: the rainy season from May to October, followed by a period of lesser precipitation and then a dry season from February to April.

The mean temperature is 29°C in HCM-city, 25°C in Hue, and 21°C in Hanoi. The rains brought by the monsoon winds blowing from the Indian Ocean are generally abundant in the north and south. Humidity is often around 90% between May and December.

It’s possible to climb year round in the South.

"To be a decent aid climber you must have the following qualities:
- Alcoholic (helps with others below)
- Stupid
- Suffer short term memory loss
- Moronic
- Obsessed with gear over climbing. "
