Best Time to Visit Shanghai
The best month to visit Shanghai is October. During this window, you avoid the oppressive humidity of summer and the bone-chilling dampness of winter. Temperatures hover between 15°C and 23°C (59°F to 73°F). The blue skies provide the best visibility for the Lujiazui skyline. While the Golden Week holiday stays busy, the rest of the month offers manageable crowds and reasonable hotel rates. You get dry weather, comfortable walking conditions, and the city’s best seasonal food, specifically the hairy crab season.
Month by month
January in Shanghai
January is the coldest month. Temperatures range from 1°C to 8°C (34°F to 46°F). It rarely snows, but the wind chill off the Huangpu River is piercing. Tourism is at an annual low, so hotel prices are at their floor. You will find short lines for the Shanghai Tower. However, many shops close late in the month for the lead-up to the Lunar New Year. Pack heavy thermal layers.
February in Shanghai
February sees temperatures between 2°C and 10°C (36°F to 50°F). The main event is the Chinese New Year (Spring Festival). The city undergoes a massive shift: millions of migrant workers leave, making the streets eerily empty, but tourist sites become packed with domestic travelers. Expect price hikes for luxury hotels. Visit the Yuyuan Garden Lantern Festival, which is the cultural highlight of the month despite the crowds.
March in Shanghai
March marks the transition to spring. Temperatures rise to between 5°C and 13°C (41°F to 55°F). Rainfall increases as the "plum rain" season approaches. It is a shoulder season with moderate pricing. This is the month for cherry blossoms. Head to Gucun Park or Tongji University to see the blooms. The weather is unpredictable; you will need a waterproof jacket and layers to handle the swinging temperatures.
April in Shanghai
April is one of the most pleasant months. Expect temperatures between 11°C and 19°C (52°F to 66°F). The city is green, and the air is fresh. Crowds are moderate except during the Qingming Festival (Tomb Sweeping Day) at the start of the month. Prices start to climb toward peak season rates. It is the ideal time to walk the Former French Concession without overheating or freezing.
May in Shanghai
May brings consistent warmth, with temperatures ranging from 16°C to 24°C (61°F to 75°F). Avoid the first week of May at all costs due to the Labor Day holiday, which sends domestic tourism into a frenzy. Outside of that week, the weather is perfect for outdoor dining and rooftop bars. Prices are high but justified by the clear skies and comfortable humidity levels before the summer heat hits.
June in Shanghai
June is the start of the "Meiyu" or Plum Rain season. Temperatures climb to 21°C–28°C (70°F–82°F). Humidity becomes a factor. Expect frequent, sudden downpours. Prices are stable, but the dampness makes outdoor sightseeing uncomfortable. Use this month for indoor attractions like the Shanghai Museum or the West Bund Art Museum. Always carry an umbrella; you will use it daily for both rain and sun.
July in Shanghai
July is hot and oppressive. Temperatures average 25°C to 33°C (77°F to 91°F), but the heat index often exceeds 40°C (104°F). This coincides with school summer holidays, meaning major landmarks are crowded with families. Hotels are expensive. Realistically, you will spend most of your time in air-conditioned malls or underground. If you visit, go to the Bund at night to catch the river breeze and the light show.
August in Shanghai
August remains peak summer. Temperatures stay high, ranging from 26°C to 33°C (79°F to 91°F). This is also the peak of typhoon season. While direct hits are rare, heavy wind and rain can disrupt flights and trains. Crowds remain thick and humidity is high. It is a good month for the Shanghai Beer Festival or exploring the underground malls. Book high-end hotels well in advance as local staycations drive up prices.
September in Shanghai
September is a transition month. Heat persists early on, but by the end of the month, temperatures drop to a comfortable 20°C to 27°C (68°F to 81°F). The humidity begins to break. The Shanghai Tourism Festival usually starts now, offering discounts on many attraction tickets. It is a smart time to visit just before the October rush, as you get summer weather without the peak summer crowds.
October in Shanghai
October is the best time to visit Shanghai. Temperatures range from 15°C to 23°C (59°F to 73°F) with very little rain. After the first week (Golden Week) ends, the city settles into a perfect rhythm. This is prime season for eating Hairy Crab (Dazha Xie), a local delicacy. Prices are moderate mid-month. The air is crisp, making it the best time for photography along the Bund or Longhua Temple.
November in Shanghai
November is the best-kept secret for Shanghai travel. Temperatures are cool, between 9°C and 17°C (48°F to 63°F). Rain is rare. The fall foliage is at its peak, with gingko trees turning bright yellow across the city. Crowds are thin because there are no major public holidays. Hotel rates drop significantly. It is the best month for cyclists to explore the Suzhou Creek pathways or the side streets of Jing’an.
December in Shanghai
December is cold and grey, with temperatures between 3°C and 11°C (37°F to 52°F). It feels colder than the thermometer suggests due to the humidity. There is no central heating in many older buildings, which can catch travelers off guard. Christmas isn't a public holiday, but malls go all out with displays. Prices are low, and the city is relatively quiet until New Year’s Eve. Visit the Xintiandi district for festive markets.
Cheapest time to visit Shanghai
The cheapest time to visit Shanghai is from early January to late February, excluding the specific dates of the Lunar New Year. During this window, international and domestic travel slows down. Business travel also dips, meaning five-star hotels in Pudong and Jing’an often slash rates by 30% to 50% to fill rooms.
Flight prices to Shanghai are generally at their lowest in November and March. These shoulder months offer a balance: you avoid the holiday price hikes of May and October but don't have to endure the freezing temperatures of mid-winter. For the absolute lowest price, book your stay for the second week of January.
When to avoid Shanghai
Avoid Shanghai during the "Golden Weeks." These are the National Day holiday (October 1–7) and the Chinese New Year (dates vary in January or February). During these seven-day windows, hundreds of millions of people travel within China. Shanghai’s major sites like the Oriental Pearl Tower and Yuyuan Garden become nearly impassable. Public transport is strained, and hotel prices can triple.
You should also be cautious of the "Plum Rain" season in June and July. It isn't just a light drizzle; it is persistent, heavy humidity that makes clothes never truly feel dry. If you dislike heat, avoid July and August. The combination of 35°C (95°F) heat and 80% humidity is physically draining for outdoor sightseeing.
Best time for good weather
For the most comfortable weather, target two windows: April to May and September to October.
October is the winner for dry, clear days. The humidity is at its annual low, and the "Shanghai Blue" skies are most frequent. April and May are slightly more humid but offer the best flora, with tulips and cherry blossoms. During these months, you can walk 15,000+ steps a day without the risk of heatstroke or frozen extremities. These windows also provide the best visibility for the observation decks in the Lujiazui skyscrapers.
Best time for fewer crowds
To see Shanghai without the masses, visit in November or the two weeks following the Chinese New Year (usually late February or early March).
November is particularly effective. Students are in school, there are no public holidays, and the weather is still pleasant enough for walking. Tuesday through Thursday are the quietest days for major museums and the Disney Resort. If you must visit during the summer or spring, aim for early mornings (before 9:00 AM) at major landmarks to beat the domestic tour groups that arrive by mid-morning. Winter is also quiet, but the trade-off is the biting cold and grey overcast skies.
