Vietnam Weather by Month: Your Simple, Real-World Guide

Vietnam’s weather runs on three overlapping rhythms.

In the north (Hanoi, Sapa), January–February is cool, clear, and sometimes misty—Tết season with crisp mornings. March turns warm and mild; April warms further. May brings heat with occasional showers, then June–July is the muggy, rainy stretch. August stays warm with lots of rain. Skies clear again in September (golden autumn), October is dry and fresh, November cool and dry, and December can feel chilly and gray.

Along the central coast (Da Nang, Hoi An), winter is the dry, sunny time: January–February are bright and festive, March is classic beach weather, April is hot, and May often runs into a long dry spell. From June it stays beachy and hot, but by late July and into August the region becomes storm-prone; September is wet and stormy, and October is the peak for typhoons. Rains ease in November, turning dry and comfortably cool by December.

In the south (HCMC, Phu Quoc), December–March is the dry, sunny season; April is the heat peak. The wet season starts in May with hot days and occasional showers, becomes fully tropical in June–July, and continues with brief, intense storms in August. Showers taper in September and October, and November is dry again with a festive feel.

“Sweet spot” picks shift through the year: January–February favor Hoi An/Da Nang and the Mekong; March is excellent almost everywhere (Nha Trang shines); April highlights beach time in Nha Trang and Phu Quoc; May–June favor the central coast; July can still work around Da Nang/Quy Nhon; August is ideal for Sapa’s rice terraces; September favors Hanoi and the northern highlands; October suits Ha Long Bay and Hanoi (but generally avoid the central belt); November is a good transition month with Ho Chi Minh City and the Mekong in fine form; and December brings another country-wide sweet patch, especially Saigon and Phu Quoc.
