2026 End of Heat Arrives!
The day after tomorrow (August 23), the Chushu solar term will arrive, marking the gradual dissipation of summer heat and the transition toward cooler weather. In 2026, Chushu falls on the 11th day of the seventh month of the traditional Chinese lunisolar calendar, signaling the seasonal transition from summer to autumn.
End of Heat (Chushu, 处暑) is the 14th of the 24 solar terms in the traditional Chinese lunisolar calendar. It signifies the end of the intense summer heat, as the dog days of summer are nearing their conclusion. The character “Chu (处)” in Chushu means “to stop” or “to cease,” symbolizing the gradual retreat of extreme heat and the arrival of autumn. As an important transition between summer and autumn, Chushu also reflects the seasonal rhythm of traditional Chinese agriculture and daily life.
The Chushu solar term is associated with many traditional customs. In terms of diet, there is a folk saying that eating duck during Chushu helps protect against autumn dryness. Duck meat is traditionally considered cooling and nourishing, making it a popular seasonal food. Eating pears is also a common Chushu tradition, as pears are believed to help replenish fluids, relieve heat, and moisten dryness. In some regions of China, people also participate in activities such as releasing river lanterns, enjoying seasonal foods, and celebrating the beginning of the autumn harvest.
As Chushu approaches, the global semiconductor industry is experiencing a “heatwave” of its own. SK Hynix recently announced plans to buy back and cancel KRW 40 trillion worth of its own shares, equivalent to approximately $28.6 billion. The move represents one of the largest share buyback programs ever announced by a South Korean listed company and highlights the strong cash-generation capabilities of leading memory chipmakers amid growing demand for AI-related memory products.
The AI industry is also continuing to attract significant investment. AI startup Velaura AI has reportedly raised $110 million at a valuation exceeding $1 billion, becoming another example of the strong investor interest surrounding artificial intelligence. As demand for AI applications, computing power, and data infrastructure continues to expand, semiconductor manufacturers and AI startups are benefiting from the rapid development of the broader AI ecosystem.
Meanwhile, the graphics card market is also facing significant price pressure. Intel’s Arc Pro B70 GPU has reportedly seen its price surge by as much as 46% in just one month in some markets. The professional graphics card features 32GB of GDDR6 memory and is designed for demanding workloads such as AI development, machine learning, and professional computing. The sharp price increase highlights the continued pressure on high-performance GPU and memory supply amid strong demand for AI computing.
During Chushu, the temperature difference between day and night gradually increases, so remember to adjust your clothing accordingly and stay hydrated to protect against seasonal changes. Similarly, although the semiconductor industry may experience short-term market fluctuations, demand for AI computing, memory, GPUs, and data centers continues to drive technological innovation. As the heat of summer fades, the “heat” of technological development shows no sign of cooling down.
