Climate

To be honest, we didn't expect it to be as cold as it is - although we're prepared for even snow since we wanted to trek Fansipan.
Sa Pa in the north was really cold, as already mentioned. Felt like about far below 10 degree C sometimes but there was surely a big deal of humidity chill effect.
Hanoi got quite chilly too during the night making a sweater necessary.
Now that we're already south of the "Wolkenscheide" (north of Da Nang) which separates north an south Vietnam we expected it to be at least at lot warmer here. We were wrong.
Tonight we're taking the sleeping bus to Nha Trang. The weather forecast predicts about 30 degrees maximum :)
By the way, it's apparently Buddhist New Year today!
