Hanoi · Month comparison
January vs April
April ranks #1 overall vs January at #7. The best weather month — warm, sunny, low crowds, and the Old Quarter at its most photogenic.
January
#7 of 12 months
Strong option
Cool, misty, and festive — Tet preparations transform the Old Quarter with flowers and lanterns.
- ↑Tet (Lunar New Year, late January or early February) preparations dominate the month: Hang Ma Street fills with lanterns and decorations, peach blossom trees appear throughout the Old Quarter, and Hoan Kiem Lake hosts evening flower markets — the most visually spectacular seasonal transformation in Hanoi
- ↑Rainfall is minimal at 18mm — the driest and coolest period of the year means comfortable walking without heat or rain; a cardigan and a good pair of shoes is all you need
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

January trade-offs
- ↓Only 2.5 sunshine hours daily — January is the gloomiest month in Hanoi's calendar; the famous skyline and street scenes are best photographed in soft overcast light, but blue-sky photographs require patience
- ↓At 18°C average high, Hanoi is genuinely cool by Southeast Asian standards — pack a layer for evenings; this surprises visitors who arrive expecting tropical warmth
- ↓If Tet falls in January, most restaurants, shops, and attractions close for 1–2 weeks surrounding the holiday; beautiful but logistically difficult for unprepared travellers
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
