December Splits Vietnam in Three: Plan Around the Region, Not the Country
The single 20-26C figure quoted for December hides a country pulling in three directions, and which one you book decides your trip. The south is the safe pick: Ho Chi Minh City sits around 32C by day and 24C at night, with December marking the start of its dry season, so the Mekong Delta and Cu Chi run reliably. The north has flipped to genuine winter. Hanoi runs cool and dry at roughly 23C down to 15C, and Sapa's daytime is closer to 8-15C, with frost coating the high ground around Fansipan and the O Quy Ho Pass on cold-front mornings. Pack a real jacket for the north, not a fleece.
The honest catch is the center. Hoi An is still shaking off its wet season, averaging around 220mm of rain across December as the October-November flood peak recedes, so early-month visitors can still hit washed-out lantern evenings. Time the central coast for the back half of the month.
- December 20 to January 5 is international high season: a Hoi An four-star room near $70 in May can reach about $140 over the holidays, so lock rooms 2-3 months out.
