Welcoming the Summer Solstice: A Time of Nature and Tradition

On Saturday, June 21, 2025, we welcome the arrival of the Summer Solstice, one of China’s twenty-four solar terms. This moment not only marks a seasonal shift but also carries rich cultural meanings and traditional customs.

Astronomical Significance

From an astronomical perspective, the sun reaches its northernmost point of the year on the Summer Solstice. It shines almost directly over the Tropic of Cancer. As a result, the northern hemisphere experiences its longest day of the year. Daylight hours reach their annual peak.
This rare alignment makes the Summer Solstice a special moment in the Earth’s annual cycle.

Seasonal Changes in Nature

The Summer Solstice brings noticeable changes to the weather. Across China, temperatures rise, sunshine increases, and crops grow quickly.
During this time, crops demand more water, inspiring the saying: “Summer Solstice rain is worth a thousand gold.”
The strong heating of the ground leads to active air convection. This often results in afternoon thunderstorms, which are brief but intense.
These short bursts of rain, known as “summer rain across the field ridge,” provide both moisture and relief from the heat.

Traditional Customs and Cultural Significance

In Chinese tradition, the Summer Solstice is rich in folk customs. One of the most well-known is eating noodles.
There is a saying: “Eat dumplings on the Winter Solstice and noodles on the Summer Solstice.”
New wheat is typically harvested by this time. Making noodles with fresh wheat flour is both a celebration and a way to thank nature.
Different regions have their own favorite styles. In northern China, people enjoy cold noodles with sesame sauce. In the south, options include Yangchun noodles or noodles with stir-fried sauce.

Another important tradition is offering sacrifices to gods and ancestors. In ancient times, people marked the Summer Solstice by honoring the harvest and praying for blessings.
This reflects the Chinese people’s deep respect for their ancestors and their gratitude for nature’s gifts.

The “Summer Nine-Nine” Period

The Summer Solstice also begins the “summer nine-nine” period. Starting from this day, people count time in nine-day cycles.
Each cycle reflects a phase in the transition from hot summer to cooler autumn. People adjust their daily routines accordingly.

Impact on Agriculture

This period is also crucial for farming. Crops are in a rapid growth stage, and farmers are hard at work.
They must manage fields by weeding, fertilizing, and preventing pests — all in time to ensure a good harvest.
In northern China, for example, summer corn is thriving. Farmers care for these seedlings with great attention, looking forward to a fruitful autumn.

Embracing the Moment

As the Summer Solstice nears, let’s take time to observe nature and connect with tradition.
Whether it’s enjoying a bowl of noodles, joining in sacrificial ceremonies, or simply watching the changing skies, this is a time to appreciate the world around us.
Let’s welcome the arrival of passionate summer with open hearts and joyful spirits.
