Nha Trang weather by month: rainy season, typhoons, best time

Nha Trang climate by month, the October–December rainy season, the November 2025 floods and how weather affects renting.

The full guide is available in Russian for now. The key points:

• Temperatures hardly change (about 27-33 C by day all year); what changes is rain and the sea. October and November are the wettest, roughly 300-380 mm a month.
• March to August is the dry, calm and best time for the sea; January-February is cooler, with sea water around 25 C.
• The real risks are flooding of the Cai River, streets and mountain passes, as in November 2025, not a direct typhoon hit.
• When renting, check ventilation, ceilings and whether the flat flooded in autumn 2025; keep a 2-3 day stock of water and food.
