Though somewhat removed from the equator, the city still has a mild tropical monsoon climate. That means that as far as the weather is concerned, you can visit anytime. The limiting factor is the crowd – in the summer months between May and September, the tourist population of the city swells greatly. Danang’s only real seasons are monsoon and winter, with brief moderate periods in between.
Dry Season (January–April): Though there’s some rain in January, by the time March rolls around, precipitation is one fourth of September. Even at its coolest, in January temperatures rarely fall below 20 degrees Celsius.
Summer (May–August): Late April and early May, when the days aren’t too hot yet, are everyone’s best season to visit. However, the peak season only really starts during mid to late summer as these are vacation months. At its hottest, temperatures are around 35 degrees Celsius.
Monsoons (September–December): The three months are incredibly wet, beginning in middle September. The best you can say for these days is that the hotels are cheaper. It’s actually the worst time to visit, because the beaches are dead. Average temperatures are around 25 degrees Celsius.
