What do you mean "temperature in August, temperature in September, warm spring in October"?

It refers to some areas in the south. It's warm in August and September of the lunar calendar, and it's as warm as spring in October.

"It's warm in August, warm in September and sunny in October" is a weather proverb. August, which is "warm in August", is autumn and February in the four seasons, also called Mid-Autumn Festival, which is still relatively warm at this time; "September temperature" lunar calendar in September, the climate is stable, rainfall and humidity are relatively reduced, forming a stable climate and crisp autumn; "There's Koharu in October" means that October in the lunar calendar has the same warm weather as spring and March.

In October of the lunar calendar, some areas in southern China will still have warm weather like spring. Controlled by high pressure, it turns cloudy and sunny locally, with strong sunshine and rising temperature. The temperature difference between day and night is a little big, and it is hot in the afternoon, which makes peaches and plums and other plants mistakenly think that spring is coming and flowering for the second time. This is the so-called "August is warm, September is warm, and October is sunny."

Spring in October literally means "presenting a feeling of warm spring", and October is a season with mild climate like spring. At this time, some plants will bloom (twice a year) because the temperature, humidity and temperature are moderate. Why is this weather phenomenon? Because October every year, it is already a relatively short month of sunshine.

The temperature will be very low in the morning and evening, but as the sun rises, the temperature will rise slowly, and it will feel warm as spring at noon; In contrast, 10 just arrived in beginning of winter and has not yet entered the cold winter month. In addition, the temperature difference between noon and morning and evening is large, which makes people feel like a warm-up after winter.
