Summer in Guiyang is warm and characterized by high humidity, with average temperatures during this period reaching 22-24°C. Spring and autumn are pleasant transitional seasons with moderate temperatures, gradually rising in spring and falling in autumn.

One of the key features of the weather in Guiyang is the significant number of rainy days throughout the year. The highest amount of rainfall and, accordingly, wet days occurs from late spring to mid-summer, peaking in May and June when the number of rainy days can exceed 20. Even in relatively drier winter months like November and December, the number of days with precipitation remains fairly high (12-13 days), indicating frequent cloudiness and possible drizzle. This creates a feeling of high humidity all year round.

The climate in Guiyang is characterized by noticeable seasonal temperature changes throughout the year. The coldest month is January, with an average temperature of about 5.1°C, minimum night temperatures around 2.0°C, and daily highs up to 8.2°C. In contrast, July and August are considered the hottest months, with average temperatures reaching 24.0°C. During this period, daytime highs can rise to 27.5-27.8°C, while nighttime lows stay around 20.2-20.6°C. Thus, the annual temperature range is quite wide, offering diverse conditions for travelers.

The summer months in Guiyang, from June to August, are pleasantly warm. June brings an average temperature of 21.9°C, while July and August average around 24.0°C. Daytime temperatures at the height of summer are comfortable, usually not exceeding 28°C. Nights also remain warm. Daily temperature fluctuations in summer are small, with the difference between maximum and minimum temperatures averaging 6-7°C. Given that May and June see a high number of rainy days (24 and 22 days respectively), the start of summer can feel quite humid.

Winter in Guiyang, especially in December and January, is cool but without extreme frosts. Average monthly temperatures range from 5.1°C to 5.7°C. At night, the temperature can drop to 2.0-2.5°C, and during the day, the air warms up to 8-9°C. February is already noticeably warmer, with an average temperature of 7.0°C.

In Guiyang, precipitation occurs throughout the year, but its intensity and frequency vary significantly by season. The city is generally characterized by humid weather, but wetter and drier periods can be identified based on monthly average data.

The highest amount of rainfall occurs from late spring to mid-summer. June is the month with the highest average precipitation, reaching approximately 9 mm. However, May stands out for the frequency of rain, with an average of about 24 rainy days and about 7 mm of precipitation. Overall, from May to July, rain is quite frequent, although the total number of millimeters suggests moderate rather than heavy downpours. For example, in May and June, it rains more than two-thirds of the days in the month.

The drier season falls in late autumn and winter. November and December are the driest months, with average monthly precipitation of only about 2 mm. The number of rainy days also decreases, reaching a minimum in December (about 12 days). Despite the overall decrease in precipitation, even in these driest months, the probability of rain remains on about a third or even nearly half of the days (for example, 13-16 days with precipitation from November to January). Given the winter temperatures, precipitation in the cold season falls predominantly as rain.

When planning a trip to Guiyang, it's important to prepare for its humid climate and frequent precipitation throughout much of the year. A key item in your luggage should be an umbrella or a light raincoat, as the number of "wet days" is significant even in months with less total rainfall. With this in mind, waterproof or quick-drying shoes will come in very handy. The principle of layering clothes will be your best ally, allowing you to adapt to temperature changes throughout the day and between seasons.

In the winter months (December to February), when average temperatures hover around 5-7°C and minimums can drop to 2°C, be sure to bring warm clothes: sweaters, fleece jackets, an insulated jacket, a hat, a scarf, and gloves. In spring (March to May) and autumn (September to November), the weather becomes milder, with temperatures ranging from 11°C to 21°C. During this period, you will need light jackets, windbreakers, and the ability to dress in layers. Summer in Guiyang (June to August) is warm, with an average temperature around 22-24°C. Light, breathable clothing is suitable for this time of year, but don't forget sun protection on clear days and a light waterproof jacket or poncho, as the summer months—especially May and June—are characterized by the highest amount of rainfall and "wet days."

Regardless of the season, comfortable walking shoes are an absolute must for comfortably exploring Guiyang and its surroundings. If you plan on nature trips, choose shoes with good grip. Don't forget a portable charger for your gadgets and perhaps a small daypack for excursions to hold your raincoat, a water bottle, and other essentials.
