Bangkok taught me that 'too hot' is a real concept. I arrived in April thinking I could handle it — 36°C with 70% humidity is genuinely dangerous if you're not acclimated. Pack moisture-wicking everything, plan indoor activities for 11am-3pm, and embrace the night markets. November-February is the survival window. The data backs this up: those months drop to a manageable 30°C with lower humidity and almost no rain.
