Are the summer monsoons in SE Asia really that bad?
I'm tentatively planning to travel to SE Asia for 1.5–2 months next summer (probably May and June). My og itinerary was to start in Bangkok/Ayutthaya, cross Cambodia, and then snake my way up Vietnam. However I'm wondering if the summer monsoons are gonna throw a wrench in that plan, especially with this "Super El Niño" I keep reading about. Sounds like the heat/humidity in particular will be brutal (I'm from Toronto, which can get pretty hot and sticky during the summer, but it's not sustained like in SE Asia). Should I be skipping Cambodia and Southern Thailand and instead focusing on the mountainous north (Luang Prabang, Chiang Mai, Chiang Rai, etc.) to escape the heat/floods? Or should I just suck it up, stay inside in the morning, embrace the sweat, and stick to my og plan? Haven't found a straight answer on google so would love to hear from people with actual experience of summer monsoons in the region
