Shanghai’s Climate at a Glance
Shanghai sits at 31° North on the eastern coast of China, with a humid subtropical climate (Köppen Cfa). Four distinct seasons divide the year sharply. Annual rainfall averages 1,150 mm (46 inches), distributed unevenly with a heavy rainy season from late May through mid-July (the East Asian monsoon, locally called meiyu or “plum rain”). Winters are influenced by cold continental air masses from the north; summers by warm humid air from the East China Sea.
Annual averages: warmest month is July (average high 32°C / 90°F), coldest is January (average high 8°C / 46°F). Wettest month is June (average rainfall 180 mm / 7 inches), driest is December (50 mm / 2 inches). Sunniest months are October and November.
January
Average high: 8°C (46°F). Average low: 1°C (34°F). Rain days: ~10. Rainfall: 50 mm.
The coldest month. Daily temperatures hover around freezing in the early morning and warm slowly through the day. Light snow can occur but rarely accumulates. The damp cold feels colder than the temperature suggests; many indoor spaces use space heaters rather than central heating.
What to expect: Crisp air, occasional clear days with great photography light, gray drizzle days, occasional flurries. Lunar New Year often falls in late January or early February, bringing the year’s biggest crowds at temples and tourist sites.
Pack: Heavy coat, thermal layers, hat, gloves, waterproof shoes.
Best for: Indoor museum-heavy itineraries, Lunar New Year culture, lower hotel prices.
February
Average high: 10°C (50°F). Average low: 2°C (36°F). Rain days: ~9. Rainfall: 60 mm.
Slightly warmer than January but still firmly winter. Late February sees the first plum and magnolia blossoms in protected gardens. Lunar New Year usually falls in February (varies by lunar calendar) and brings dramatic crowds and cultural energy.
What to expect: Continued cold, occasional gray weeks. Brief warm spells late in the month. Clearer skies than January on average.
Pack: Heavy coat, thermal layers, waterproof shoes.
Best for: Lunar New Year celebrations, lower hotel prices outside the holiday week itself.
March
Average high: 14°C (57°F). Average low: 6°C (43°F). Rain days: ~12. Rainfall: 90 mm.
Spring begins. Cherry blossoms peak in late March in central Shanghai parks (Gucun Park is the most famous, but the Pudong waterfront and the former French Concession have notable trees too). Days are warming but mornings can still be cool.
What to expect: Light jacket weather. Rainfall is moderate, with rainy days alternating with bright sunny days. Allergies (especially to plane tree pollen) can be a factor for sensitive travelers.
Pack: Light jacket, layers, umbrella, allergy medication if needed.
Best for: Cherry blossom photography, beginning of pleasant outdoor walking weather.
April
Average high: 19°C (66°F). Average low: 11°C (52°F). Rain days: ~12. Rainfall: 95 mm.
One of the two ideal months for visiting Shanghai. Comfortable temperatures, blooming flowers, manageable rainfall, and good light. Crowds remain manageable except during the Qingming Festival (April 4–6).

What to expect: Variable but generally pleasant. Light rain showers some afternoons. Outdoor activities — Bund walks, French Concession strolls, day trips — at their best.
Pack: Layers, light rain jacket, comfortable walking shoes.

May
Average high: 24°C (75°F). Average low: 16°C (61°F). Rain days: ~12. Rainfall: 110 mm.
Late May begins the transition into the rainy season. Early May is still ideal travel weather; late May can see the first sustained rainy stretches. May 1–5 is a national holiday period with very high domestic tourism.

The hottest month. Summer afternoons regularly reach 35–37°C with humidity above 80%. Heat indexes can exceed 40°C. Late July sees the start of typhoon season for the eastern Chinese coast.

Pack: Heavy coat, thermal layers, hat.
Best for: Christmas-and-New-Year visitors, photographers attracted to clear winter light.
Typhoons and Severe Weather
Shanghai is occasionally affected by typhoons in the East Asian typhoon season, roughly July through September. Most are deflected by the time they reach Shanghai’s latitude, with the city more often experiencing the typhoon’s outer rain bands than direct hit. A direct landfall typhoon happens roughly once every two to three years.
What to expect during a typhoon advisory: Flights and trains may be canceled or delayed. Schools close. Outdoor activities are restricted. Most museums and major attractions remain open. Hotel staff will keep guests updated.
Tracking typhoons: The Shanghai Meteorological Service publishes regular advisories. International travelers can monitor via the Joint Typhoon Warning Center website or major weather apps.
Outside the typhoon window, severe weather is rare. Heavy thunderstorms occur occasionally in summer; cold snaps with heavy snow occur occasionally in winter.
