Just want to put it out there for Vietnam and Cambodia for this time of year (sorry to hijack, Freya)

My parents are there at the moment. They got to Cambodia a few days ago, they were in Vietnam since the start of July. It's been 38 degrees with 95% humidity. They're on a tour, have been having 3-4 showers a day and walking around with spray water bottles. My stepdad has ended up on a drip. So if you want to go/take kids, don't go this time of year.
