Hanoi taught me that 'winter' in Southeast Asia is relative — but still real. I arrived in January in a t-shirt and shivered through 14°C with 85% humidity. That damp cold cuts through layers in a way the thermometer doesn't capture. Pack a fleece and light jacket November-February. The nightmare window is June-August: 33°C, 80% humidity, and downpours that flood the Old Quarter streets. May and October are the smart traveler's picks: 27°C, lower humidity, manageable rain. Always carry a compact umbrella year-round — Hanoi averages 1600mm and the rain comes fast.
