Best Time to Visit Da Lat
Recommended: Dec to Mar
When to go
December to March is the dry, clear window: highs 21-25C, nights near 12C, and monthly rainfall under 65mm. May through October is the wet season, peaking September and October at over 240mm each, when afternoons routinely wash out. November is the transition and often good value. Whenever you come, evenings are cold by Vietnamese standards.
