What Is “Suzukaze itaru” (涼風至)?

"Suzukaze Itaru" (涼風至, "cool winds arrive") is one of the Shichijūni Kō (72 microseasons) and marks the first microseason of Risshū (立秋), the beginning of autumn in the Nijūshi Sekki (24 solar terms). It typically falls between around August 7 and August 11 each year. According to the traditional calendar, this is the time when, amid the lingering summer heat, a faintly cool breeze begins to quietly stir. In reality, the weather is often still at the height of midsummer during this period. However, in Japan's traditional lunar calendar, which reflects a delicate sensitivity to the changing seasons, this was considered the time when the first subtle signs of autumn began to emerge. "Suzukaze Itaru" also marks the seasonal transition from "shochū-mimai" (暑中見舞い, mid-summer greetings) to "zansho-mimai" (残暑見舞い, late-summer greetings). After the start of autumn according to the calendar, it is considered proper etiquette to use the term "late-summer heat" (残暑) rather than "mid-summer heat," making this microseason a useful guideline when writing seasonal greeting cards and letters. The Shichijūni Kō (72 microseasons) is a traditional Japanese calendar that divides the year into 72 finely detailed seasonal phases of roughly five days each, beautifully capturing the subtle transitions of nature. "Suzukaze Itaru" is the 37th of these microseasons and remains cherished today as an evocative expression symbolizing the turning point from summer to autumn.
