Vietnam’s climate varies across its three distinct regions, so the best time depends on your itinerary. Generally, spring (February–April) and autumn (August–October) feature moderate temperatures and less rain, especially in the north (Hanoi, Sapa) and central coast (Hoi An, Da Nang). The south (Ho Chi Minh City, Mekong Delta) sees warmer, more humid conditions year-round, but tends to be driest from December to April. Summer (May–August) can be hot and humid with sporadic downpours, yet it remains a popular time for beachgoers heading to places like Nha Trang or Phu Quoc. If you plan to traverse the entire country, look for a compromise season—perhaps late winter to early spring—so you can dodge extreme climates and explore Vietnam’s urban, coastal, and highland destinations more comfortably.
