Autumn Equinox

「金气秋分,风清露冷秋期半。」

Solar Term Begins: 2027-09-22 – 2027-09-24
At the Autumn Equinox, day and night stand in equal measure, heat and cold are held in balance, and autumn has reached its midpoint. Chrysanthemums turn golden, crabs grow rich and full, osmanthus perfumes the air, and waves of ripening rice roll…
Temperature Trends
Autumn at Its Midpoint

Temperatures fall markedly. Across most of China, average daily temperatures drop below 20°C, while many northern regions fall to around 10–15°C. Morning and evening chill becomes pronounced, the contrast between day and night remains large, and the weather is cool and pleasant, bringing the celebrated condition of “秋高气爽” to its fullest expression.

Precipitation Patterns
Dry air and parched land

Autumn rains in western China continue, but overall precipitation remains relatively low. Most of the country is dominated by clear and dry weather: winds are stronger and conditions drier in the north, autumn dryness gradually becomes more apparent in the south, and rainfall approaches one of its lowest levels of the year.

一
Thunder Ceases

After the Autumn Equinox, yang qi gradually declines while yin qi grows stronger, and thunder ceases to rumble. This marks the complete retreat of summer heat and the natural world’s transition from the active vitality of the warm season into the more restrained rhythm of autumn and winter.

二
Hibernating Insects Seal Their Burrows

Insects sense the colder weather and begin sealing the entrances to their nests and burrows with earth, preparing themselves against the severe winter ahead. The natural world enters a clear mode of overwintering and withdrawal.

三
Waters begin to dry up

As rainfall decreases and evaporation remains strong, water levels in rivers and lakes fall noticeably, and some shallow streams may even dry up entirely. It is a direct phenological expression of the increasingly dry climate of autumn.

「晚晴」

[Tang Dynasty] · Du Fu

返照斜初彻,浮云薄未归。

江虹明远饮,峡雨落馀飞。

凫雁终高去,熊罴觉自肥。

秋分客尚在,竹露夕微微。

Modern Translation

The slanting light of the setting sun has just broken through the clouds, while thin floating clouds still linger without fully dispersing. A bright rainbow arches over the river like a long dragon drinking from afar; in the gorge, the last remnants of rain are still falling and scattering through the air. Wild ducks and geese eventually rise high and fly away, while bears seem to sense themselves growing steadily fatter. The Autumn Equinox has already arrived, yet I, a traveler, still remain far from home; at dusk, the dew upon the bamboo leaves glimmers faintly.

In-Depth Commentary

Du Fu sets this poem against the scenery of an evening at the Autumn Equinox and writes of the feeling of living away from home. “返照斜初彻” describes the setting sun newly breaking through the clouds after rain, while “浮云薄未归” writes the thin clouds still drifting and not yet dispersed. “江虹明远饮” compares the rainbow spanning the river to a long dragon drinking from the water, creating a magnificent image, while “峡雨落馀飞” captures the lingering traces of rain in the gorge as the shower begins to end. Rainbow and rain, distance and nearness, together create a broad sense of space. “凫雁终高去” writes wild geese flying south, one of the seasonal signs of the Autumn Equinox; “熊罴觉自肥” writes animals sensing the autumn chill and accumulating fat in preparation for winter. The final couplet, “秋分客尚在”, reveals that the poet remains a traveler in a foreign place even though the Autumn Equinox has arrived; “竹露夕微微” closes the poem with dew glimmering faintly on bamboo leaves at dusk, the chill of the dew quietly echoing the traveler’s loneliness. The poem weaves personal feeling into the natural seasonal phenomena of the Autumn Equinox, restrained yet substantial.
