Short answer: the best time to visit Hanoi

Hanoi's most comfortable window runs from October to early December. Days of 23–29°C (73–84°F) in October bring low rain and clear light. March and April are the runner-up, with mild air and occasional drizzle. Summer is the season to avoid, with 27–34°C (81–93°F) heat and heavy afternoon rain. Season edges differ between published guides, so treat month boundaries as approximate. Late January and February can overlap Tet, when many shops and restaurants shut for 4 to 7 days. Use the priority table below to choose.

Best time to visit Hanoi by priority

Your priority decides the month. Weather-first travelers should aim for October or November. Budget travelers can trade comfort for lower summer prices. Photographers and food-focused visitors tend to prefer the cooler months, when Old Quarter streets and Hoan Kiem Lake are comfortable on foot.

Hanoi weather by month and season

Hanoi has four distinct seasons, unlike the warm south. Spring, March to April, is mild with light drizzle known locally as mưa phùn. Summer, May to August, is hot and humid, with 27–34°C (81–93°F) days. Autumn, September to November, brings crisp, dry air and low rain. Winter, December to February, runs near 15–22°C (59–72°F) in December and 14–20°C (57–68°F) in January. Cold snaps can fall below 10°C (50°F). Published ranges vary, so use the average figures here as a guide. The national meteorological institute publishes official climate data. For fuller detail, see the Hanoi weather guide.

Hanoi's rainy season: how bad is it?

Sources disagree on the exact dates, with some starting in May and others running into September or October. Rain peaks in July and August, usually as late-afternoon downpours that can flood low streets. Plan outdoor sights for the morning and move indoors after lunch. Water puppet shows, cooking classes and cafés are reliable wet-weather options. Mid-summer evenings are the best time to walk. West Lake lotus blooms are a summer upside. More tactics are in the rainy season guide.

Hanoi in winter: December and January

December is one of the driest months, at 15–22°C (59–72°F). January turns grey, misty and damp. Many homes and hotels lack heating, so humid air feels colder than the numbers suggest. Pack a warm layer for evenings and a windbreaker for motorbike or taxi rides. Hot bowls of bun cha and egg coffee suit the weather. Read more in the December guide. Cold-weather detail sits in the January guide.

Tet (Lunar New Year): should you go?

Tet follows the lunar calendar and falls between late January and mid-February. Look up the year's exact date before booking. Locals travel home, and the city empties. Family-run restaurants, street stalls, shops and many museums close for 4 to 7 days. Transport fills up and hotel rates rise. Book trains, buses and rooms well ahead if you travel anyway. The weeks before Tet are livelier. Peach blossom and kumquat trees ride through the streets on motorbikes. January trips should read the January planning notes first.

Festivals worth timing a trip around

Mid-Autumn Festival falls on the 15th day of the 8th lunar month, in September or October. Hang Ma Street fills with paper lanterns and star-shaped toys. It is not a public holiday, so shops and transport run normally. The Perfume Pagoda Festival runs from February to April in My Duc District, south of Hanoi. Pilgrims take rowboats along the Yen Stream to Huong Tich Cave. Buddha's Birthday, usually in May, decorates Quan Su Pagoda with lotus flowers and lanterns. Lunar dates move each year. Check Hanoi's official tourism site for current events.

Peak season, shoulder season and cost trade-offs

Prices and hours checked November 2026. Published guides place peak pricing in December and January and around Tet. A second surge hits in June and July with domestic school holidays. April and May are cheaper, apart from the 30 April and 1 May holiday weekend. Summer is the low season for tours. Some operators advertise discounts of up to 40% on Halong Bay trips. As a worked example, a tour listed at ₫2,000,000 would fall to ₫1,200,000 at 40% off. That sample figure is illustrative, so compare current quotes before paying.

Pairing Hanoi with Halong Bay and Sapa by month

October to December is the prime window for Halong Bay, with clear skies and calmer sailing. Summer storms can lead to last-minute cruise cancellations. Sapa's rice terraces turn golden in autumn, while winter brings freezing fog. Book flexible cruise terms in summer. Also read the rainy season notes before you reserve.

Who should go when

Match your traveler type to a window, then keep one backup month.

• First-timers: October or November for comfortable walking.
• Budget travelers: April, May or late summer, avoiding 30 April and 1 May.
• Photographers: autumn light and Hang Ma Street lanterns.
• Food-focused visitors: October to December, with a warm layer for night stalls.
• Families: spring, with indoor stops for drizzle.
• Couples: autumn around Hoan Kiem Lake, or lotus season at West Lake.

Hanoi Month-by-Month: What Changes for Visitors

January is cool, misty and often damp, so plan cafés, museums and food stops between short walks. February can overlap Tet, which falls from late January to mid-February. Many small businesses close for 4 to 7 days around the holiday.

March and April suit flexible sightseeing. Light drizzle is common, but the heat has not arrived. Avoid the 30 April and 1 May holiday weekend if you want easier transport and lower room rates.

• May begins the hot, humid stretch; June and July add school-holiday demand.
• August remains wet, while September starts to ease toward autumn.
• October and November offer the strongest walking weather and clearest light.
• December is drier but cooler, especially after dark around Hoan Kiem Lake.

For summer visits, book outdoor landmarks early and save water puppetry, cooking classes or cafés for afternoon rain. In winter, keep lake walks and Old Quarter exploring for the warmer part of the day.
