With the arrival of the leap sixth month this year, people can't help but wonder if it means summer will be even hotter. The old saying "Two sixth months in a year, no sun during the Three Fu periods" seems to provide an answer. Let's delve into the climatic wisdom behind this old saying and its potential impact on this summer's temperature.

The Meaning of the Leap Sixth Month and Its Climate Connection

"Two sixth months in a year" refers to this being a leap year, with the leap being the sixth lunar month, meaning there are two sixth months in one year. "No sun during the Three Fu periods" suggests that during the Three Fu periods, there may be more overcast and rainy weather. Combining these two sayings, we can speculate that if a year has a leap sixth month, the following Three Fu periods may be marked by continuous rain and fewer chances of sunshine. This kind of weather change is beneficial for crop growth, as rain can moisten the soil and promote crop growth, laying a good foundation for the autumn harvest.

The Link Between Double Spring and the Leap Sixth Month and Cold Winters

Another related agricultural proverb is "Double spring with a leap sixth month, cold weather in the twelfth lunar month." Here, "double spring" refers to having two Start of Spring seasons in a year, while "cold weather in the twelfth lunar month" indicates that the weather during the twelfth lunar month, the coldest period before the Spring Festival, will be unusually cold. This proverb suggests that if a year has both double spring and a leap sixth month, the winter will likely be especially cold. A cold winter is beneficial for crops like wheat, as snowmelt can nourish the soil, and the cold can reduce pests and diseases, laying the foundation for a bountiful harvest next year.

Climate Prediction for This Year and the Wisdom of Proverbs

This year coincides with a double spring and a leap sixth month. According to the elders' words, it is very likely to be a year of abundant harvest this year and next. Although these proverbs may not be entirely accurate, they indeed contain the wisdom of our ancestors based on experience, which is worth our understanding and reflection. At the same time, in the face of hot weather, we should also pay attention to heatstroke prevention, drink more water, and avoid heatstroke.

By analyzing the old sayings "Two sixth months in a year, no sun during the Three Fu periods" and "Double spring with a leap sixth month, cold weather in the twelfth lunar month," we can conclude that a leap sixth month may indicate overcast and rainy weather during the Three Fu periods and a cold winter. These proverbs not only reflect the ancient people's observations and understanding of the climate but also provide us with a way to predict and cope with climate change. Although modern meteorological science can now offer more accurate climate predictions, these traditional wisdom still hold unique value and significance.
