The pleasant weather in Guiyang makes it suitable for visiting all year round. Have a look at our Guiyang Tours and select your time of travel. Summer and autumn are the best times for visiting some natural attractions, for the scenery is most splendid then.
If you are curious about ethnic customs, the best time to go would be during spring. Many local festivals are celebrated at that time.
The peak travel season is during the May Day Holiday (the first week of May), the National Day Holiday (the first week of October) and the summer holiday (July and August), with many more Chinese tourists then than at other times.
You are recommended to confirm and book your tour as early as possible, and let your guide help you avoid the crowds.
Spring is from March to May. It is warm but changeable, with some short cold spells. Rainfall is frequent, but mostly just drizzle. Prepare shirts, light sweaters, coats and umbrellas for the spring in Guiyang.
Spring is a great time for a countryside getaway, and to visit minority villages. If you arrive during festival time, you will be invited to join the celebrations! Check the dates of minority festivals.
Spring is also a good time for a day trip in the city or to visit Qingyan Ancient Town.
Summer is from June to September. Located in a mountainous region and surrounded by mountains which are abundant in forests, Guiyang boasts comfortable summer weather. It is not excessively hot, with fresh air, and abundant rain which mostly falls at night.
The hottest month is July, with average temperature of 24°C (75°F). The average temperature in the summer months is 23 °C (73 °F); the average high temperature ranges between 25 °C (77 °F) and 28 °C (82 °F), while the average low temperature ranges between 17 °C (63 °F) and 20 °C (68 °F).
Any summer clothes will do, such as shorts, shirts and skirts, but you are also advised to bring a light coat for the evenings and even a sweater for visiting mountainous areas. Since the wind is stronger at higher altitudes, a raincoat is often more useful than an umbrella when you visit mountainous areas.
Some natural attractions in and around Guiyang will enjoy their most splendid scenery in summer, like Huangguoshu Waterfall and Fanjing Mountain. Paths, however, can be slippery after the rain, and a good pair of shoes is recommended.
Autumn is short, from October to November. The weather feels cooler with autumn breezes, and there is more drizzle.
Some warm clothes, like jackets, coats and sweaters, should be prepared. If you feel your clothes are not warm enough, let your guide take you to buy some more.
With less rainfall than summer, autumn is a good time to travel and see both natural and cultural attractions in and around Guiyang. An umbrella will still be necessary.
Winter is from December to February. It is wet, cold and gloomy in Guiyang; but not very windy. The drizzle seems endless and the humidity makes it feel cold, even though the temperatures are not actually very low.
Only occasionally, the temperature falls between 0°C (32°F) and -10°C (14°F), and there are some light snowfalls at higher altitudes. The average low and high temperature respectively is 4°C (39°F) and 11°C (52°F) in December, 2°C (36°F) and 9°C (48°F) in January, and 3°C (37°F) and 11°C (52°F) in February.
Prepare thick sweaters and overcoats or down-jackets, and bring an umbrella when traveling in winter.
Winter is the off season and there are far fewer travelers. Some mountainous areas have snowfall, creating amazing scenery, but you may need to be in better physical condition and to have some professional equipment to travel to such places. Would you like a challenge?
