Yuxi, a city located in Yunnan Province, China, experiences a unique climate influenced significantly by the solar terms. These solar terms, or “Dongji,” are a traditional Chinese system of dividing the year into 24 segments based on the position of the sun in the celestial sphere. Each term roughly corresponds to a 15-day period and marks significant changes in the natural world and agricultural practices. This article delves into the impact of these solar terms on Yuxi’s climate, culture, and daily life.
Climate Patterns and Weather Changes

The Spring Equinox, occurring around March 20th or 21st, marks the beginning of spring in Yuxi. During this time, days and nights are of equal length, and temperatures start to rise. The weather becomes more humid, and there is an increase in rainfall, which is essential for the agricultural activities in the region.

The Summer Solstice, around June 21st or 22nd, is the longest day of the year in Yuxi. This period is characterized by hot and humid weather, with temperatures often soaring above 30°C (86°F). The sun’s intense rays can lead to heatwaves, and the city experiences its peak rainfall during this time.
3. Autumn Equinox (Qiuji)
