Da Nang can be said to be the only few places in Vietnam with predictable weather. Temperature is highest from May to September, hovering around 24 Celcius degree. Unlike Hue, the proximity of Da Nang to Pacific Ocean keeps it cooler than it should be. In other months, the temperature does not drop below 20. Rainfall level is highest in winter month from September to January. That leaves February to May the best time to visit Da Nang. If you can, try to avoid the summer months from June to the end of August, when Da Nang becomes a popular retreat for domestic tourists.
