Vietnam
Best Time to Visit Hanoi
Hanoi's climate divides sharply into two halves: a cool, dry winter (November to April) and a hot, humid summer monsoon (May to October). The best visit falls between these extremes, when temperatures are mild and humidity manageable without peak-season crowds.
✦ Visit October or early November for the climate-to-crowd-to-cost sweet spot; avoid May–August unless budget is paramount and heat tolerance is high.
✅ Best months
October and November are optimal. Temperatures sit between 20–28°C, humidity drops after the summer monsoon, and crowds remain moderate—giving you comfortable exploring without the premium prices of December or the oppressive heat of summer.
🔥 Peak season
December to February, particularly Christmas and New Year. Hotel rates climb 30–50%, Old Quarter streets cram with international tourists, and domestic travellers fill temples during Lunar New Year (late January or February). Tourist sites require early arrival to avoid queues.
💷 Shoulder (best value)
September and March–April offer solid discounts (20–30% below peak) with reasonable weather. September carries residual monsoon humidity but few crowds; March–April sees warming but remains dry, with temple festivals beginning to draw local visitors.
🌙 Quietest & cheapest
May to August is the cheapest period, with discounts up to 40% and minimal tourist congestion. Trade-off: temperatures exceed 35°C with 80%+ humidity, frequent downpours make sightseeing difficult, and some rural attractions become inaccessible. Hanoi feels like a steam bath.
Hanoi season by season
Spring (Mar–May)
Weather: 15–32°C; starts dry, becomes humid by May with occasional rain
Crowds: Low to medium
Ideal for temple visits; late May approaches monsoon discomfort
Summer (Jun–Aug)
Weather: 26–36°C; high humidity (75–85%), frequent afternoon thunderstorms
Crowds: Low
Cheapest period but oppressive heat limits outdoor exploration; street food tours remain excellent
Autumn (Sep–Nov)
Weather: 22–32°C; dries progressively, humidity drops sharply by November
Crowds: Low to medium
Sweet spot: September still wet but cooling; October–November near-perfect conditions
Winter (Dec–Feb)
Weather: 10–20°C; dry and cool, occasional drizzle in January
Crowds: High (peak)
Comfortable weather but peak prices; Lunar New Year (late Jan/Feb) brings temple closures and gridlock
🎭 Events worth timing a trip around
Lunar New Year (late January or February): colourful temple fairs, street parades, and traditional food markets, though major sites shut for 3–5 days and prices spike sharply. Mid-Autumn Festival (September/October): lantern displays and children's celebrations add cultural flavour without overwhelming tourists.
🧳 What to pack
Carry a compact umbrella year-round—sudden downpours are routine in summer and winter, and Hanoi's narrow pavements leave you exposed; in winter, layers beat heavy coats since buildings lack heating despite temperatures dropping to 10°C.
