(日本語は少し下にあります) There is a saying that the weather is good for ten days after the end of the rainy season. This is old knowledge that the high pressure in the Pacific Ocean becomes stronger, hot winds from the heated sea in the south cover Japan, and sunny weather continues. It would be nice if this means the end of the humid air of the rainy season, but it also means that the intense heat is about to begin. Sigh.
