Vietnam Weather

Vietnam’s climate is a lively mix that keeps you guessing, with warm temperatures all year round and a steady supply of sunshine. You’ll find the mercury hovering between 25°C and 35°C, and the sea rarely dips below 22°C, so beach days are basically always on the cards. Rainfall and humidity do shift with the seasons, but the weather rarely feels dull or drizzly for long.

If you fancy exploring beyond the mainland, Vietnam’s islands have their own little quirks. Phu Quoc tends to dodge the worst of the autumn monsoons, while coastal spots like Da Nang and Nha Trang serve up reliable sunshine and balmy seas from late winter through spring. Whether you’re after a laid-back holibobs or a bit of adventure, Vietnam’s climate is ready to play ball.
