Written by Catherine | Updated October 22,2025

Dali is a beautiful city in Yunnan Province, China. Surrounded by water and mountains, it has rich cultural heritage, beautiful natural landscapes, and local Bai minority culture. Many people travel to Dali to get away from the busy city life. To help you plan your trip, this article is a comprehensive guide to Dali weather, weather by month, best time to visit, and best things to do in different seasons.

Dali has a subtropical highland monsoon climate, which means Dali weather is pretty mild all year round. The city gets plenty of sunshine. The yearly average temperature ranges around 15-17°C (59-63°F). Typically, seasonal temperature differences aren’t great, with no extremes in summer or in winter, but there’re a distinct wet season (late May to September) and dry season (October to April).

Dali city sits at an elevation of about 2,000 meters (6,562 feet) on a flat plateau. Erhai Lake to the east and Cangshan Mountain to the west create a natural wind tunnel, so the city gets a great deal of wind year-round. Dali is therefore nicknamed the “Windy City.” Before your trip, you can learn about Yunnan weather of nearby cities as well.

Dali’s Microclimate: Altitude, Wind, and Practical Health Tips

Altitude and Sun Exposure

The average altitude of Dali is about 2,000 meters, but the humidity is appropriate and the oxygen is sufficient. This is attributed to the excellent air passage formed between Cangshan Mountain and Erhai Lake. So for most travelers, this height is friendly and they will not feel discomfort. But intense exercise may also cause shortness of breath. For sensitive people like the elders and children, they may suffer some mild symptoms, so special attention is also needed. Dali is also in a low latitude area, resulting in a high level of ultraviolet intensity all year round. Even on cloudy days, the UV rays can also penetrate clouds and have potential effects on the skin. So do remember to bring sunscreen, sunhat and sunglasses.

Large day-to-night temperature swing

The weather in Dali is changeable in one day and the most striking feature is the large day-to-night temperature. Even in the spring-like dry season, when night falls, you will feel like in the winter. And in rainy season, though the temperature difference is not as obvious as the dry season, the temperature may drop suddenly after a rain. So a fleece coat or a light down jacket is necessary to protect you from the cold in the evening. During daytime, a short-sleeved shirt + a coat and a quick-drying clothes + a waterproof jacket are the common dress in dry season and rainy season, respectively.

The “Windy City” Reality

To enjoy a comfortable travel, some preparations will be needed to deal with the strong wind in Dali. Due to the wind chill factor, i.e., the wind can accelerate the loss of body heat, the sensible temperature is significantly lower than the actual temperature. The weather seems to be mild according to the forecast, but you will feel cold due to the wind. So during your Erhai Lake cycling or boat trips and Cangshan Mountain hikes, remember to wear a windproof jacket. Hats and gloves are also very useful.
