Wow Renaissance. You seem like a regular there. You just gave me an idea. I should go in all four different seasons to experience the weather and fruits there.
You don't want to go there during the rainy season and monsoon as there will be no fresh fruits and you will not enjoy the rain. During our winter here (November through January) it will be less humid in Thailand. From February on it will get hotter and very humid. April through June will be times for fresh fruits. Avoid July through September/October because that is the monsoon (wet) season.
I wish I was more computer savvy so I can post some of my pictures when I was in Vietnam and Thailand in 2016. I was in Hanoi, Hao Long Bay, Sapa, Bangkok, Chang Mai, Chiang Rai, Phuket, and a few more places in Thailand which I don't recall the names.
