Everyone rushes to Thailand, but Vietnam’s central coast (think Da Nang and Hoi An) is the real winter warmer. The weather is sunny and 25°C (77°F) from November to February.
The best part? You can wear all your sundresses without freezing at night. The Ancient Town of Hoi An glows with lanterns, and the food—crispy banh mi, fragrant pho—is the ultimate cold-weather antidote on the inside.

Cultural note: In Vietnamese tradition, winter is the season for tet holidays (Lunar New Year). If you visit in late January, you’ll see fireworks, dragon dances, and families celebrating with watermelon seeds. You are invited to join in.
