A practical travel-weather guide to Guiyang, China — from seasonal climate patterns to month-by-month outfit tips.
Guiyang, the capital of Guizhou Province in southwest China, sits on the eastern side of the Yunnan–Guizhou Plateau at around 1,100 meters above sea level. Thanks to its highland location, the city has a humid subtropical climate with a refreshing twist: summers are milder than in many other cities across central and southern China, while winters are damp and chilly rather than severely cold. The average annual temperature is around 15°C, with July averaging about 24°C and January around 4–5°C. Rain is most common from May to September, and cloudy skies, mist, and light rain can appear even in winter. In short, Guiyang is a city where a compact umbrella or a light waterproof jacket is useful almost all year round.
Guiyang Weather by Season
Spring in Guiyang (March to May)
Spring in Guiyang is generally mild, but it can be unpredictable. March often still carries a touch of winter chill, especially in the morning and evening, while April and May gradually become warmer and more humid. Rainfall begins to increase as the season progresses, so travelers should dress in layers and keep rain gear close at hand. A light jacket, long-sleeved shirt, and compact umbrella are ideal for spring sightseeing.
Summer in Guiyang (June to August)
Summer is Guiyang’s main rainy season. The city receives much of its annual rainfall between May and September, with June often standing out as one of the wettest periods. Even so, Guiyang’s elevation keeps the heat relatively manageable, and July averages around 24°C. Expect humid, cloudy, and rainy conditions rather than oppressive heat. Breathable clothing, waterproof shoes, a raincoat, and an umbrella are highly recommended.
Autumn in Guiyang (September to November)
Autumn is one of the most pleasant times to visit Guiyang. Rainfall gradually decreases in September, temperatures become cooler, and the weather is more comfortable for walking, sightseeing, and day trips. October can still feel chilly on cloudy or rainy days, especially in the morning and evening, so a light jacket or windbreaker is helpful. For many travelers, September offers the best balance between comfortable temperatures and reduced rainfall.
Winter in Guiyang (December to February)
Winter in Guiyang is not extremely severe, but the damp air and limited sunshine can make it feel colder than the thermometer suggests. January is usually the coldest month, averaging around 4–5°C. Fog, drizzle, and overcast skies are common, and occasional frost or light snow may occur. Instead of relying on one very heavy coat, travelers should wear warm layers, a windproof outer jacket, and comfortable insulated shoes.
Best Time to Visit Guiyang
The best time to visit Guiyang is from late August to September. During this period, rainfall begins to ease while temperatures remain mild and pleasant. This makes it a great time for exploring the city as well as nearby natural attractions such as waterfalls, lakes, and mountain scenery. Summer and early autumn are especially rewarding for lush landscapes, but visitors should still be prepared for rain. Winter is drier in terms of rainfall, but the damp, cloudy weather can feel cold, while spring and October may bring sudden temperature changes.
