Thanks for following the blog. As for weather, ho chi minh is hot all year round. If you arent used to Asia's humidity, you will be in for a shock. I recommend you to stay in Dalat where it's the coldest part of Central Vietnam. We spent a week here last time we visited because we didnt want to feel the heat anymore. Ahahha I think there are lots of tours and things to see surrounding Dalat.
North Vietnam, like Hanoi can be cold in the winter months of November to January. I think it remains cold until March?
Good luck with it. Happy travels!
Thanks for the info, appreciate it!
