Hanoi · Month comparison
July vs April
April ranks #1 overall vs July at #12. The best weather month — warm, sunny, low crowds, and the Old Quarter at its most photogenic.
July
#12 of 12 months
Worth considering
The hottest and wettest month — 33°C and 288mm of rain; Hanoi is best explored air-conditioned and after dark.
- ↑Evening Hanoi in July is genuinely excellent: the heat eases after 6pm, the Old Quarter's night markets and bia hơi culture is at its most vibrant, and street food stalls operate until midnight
- ↑The summer heat accelerates the rhythm of Hanoi's outdoor café culture; rooftop bars around the Old Quarter and Hoan Kiem Lake fill with a mix of locals and travellers after dark
April
#1 of 12 months
Best match
The best weather month — warm, sunny, low crowds, and the Old Quarter at its most photogenic.
- ↑April is the joint-best weather month in Hanoi: 26°C, 5.5 sunshine hours, and light rather than heavy rain — the Old Quarter is comfortable to explore for a full day without the humidity and heat of summer
- ↑Crowds are at their annual low outside the peak seasons; the Ngoc Son Temple at Hoan Kiem Lake and the Temple of Literature can be visited without congestion

July trade-offs
- ↓288mm of rain makes July the wettest month in Hanoi's year — sustained downpours, flash flooding in the Old Quarter's streets, and daily disruption to outdoor plans
- ↓33°C average high with 83% humidity is the hottest and most uncomfortable combination in Hanoi's calendar; daytime sightseeing is punishing
- ↓The combination of heat and heavy rain means July is structurally inferior to every other month in Hanoi — no events, no weather advantages, nothing that is genuinely best in July
April trade-offs
- ↓Rainfall increases to 88mm — light but present; afternoon showers are possible; carry a small umbrella or poncho
- ↓April is starting to become more popular as word of the good weather spreads; hotels fill faster than in February-March and prices begin edging upward
- ↓The heat is building toward summer levels by late April — daytime sightseeing between 11am and 3pm can already feel warm
