Advice needed — is September–December a bad time to backpack in Asia for our honeymoon?

Hey everyone, My partner and I are getting married in May 2026 and we’re planning a 3-month honeymoon trip around Asia. Our original idea was to go from September to December 2026, and visit countries like Vietnam, Thailand, South Korea, China, Japan, Singapore… basically a slow backpacking trip with a mix of nature, culture, and food. Now we’re having second thoughts because of the weather. I’ve been reading about monsoon seasons, typhoons, storms, flooding, etc. in this period and it’s making me nervous. I know every country has different climate zones, but overall I’m worried the trip will be a constant fight with rain, humidity or even dangerous conditions.

We can’t really travel June–September 2026 because that’s high season: super crowded and expensive everywhere. Another option is to postpone the trip to December 2026–February 2027, but that has a few downsides.

• We also want to start trying for a baby, so postponing means postponing that too.
• I’m not doing great mentally at work right now, and delaying the trip means staying longer in a job that’s draining me.

Has anyone traveled long-term in Asia around September–December? How bad is the weather in reality? Are there countries that are still great in that window, or should we just reschedule to winter? Any advice, personal experience, or route suggestions would be super helpful. Thank you! 🙏
