What does July filariasis mean?

"July fire" refers to the weather: in summer, especially in the midsummer of July, the heat is scorching, the sun is like fire, and there seems to be flames flowing in the air. At this time, when people write or talk about the hot July, most of them like to use the word "July filariasis". As a result, sentences such as "The summer solstice has passed, and the fire broke out in July", "The fire broke out in July, and the heat was unbearable" and "The fire broke out in July, and the weather continued to be hot" frequently appeared in various newspapers, radio, television, internet and other modern media. Don't you know that the real meaning of the word "July fire" doesn't mean that the weather is hot, but that the summer heat begins to fade and the weather is getting colder and colder. If we use "July filariasis" to describe the hot weather in July, it is wrong to read the meaning in the opposite direction.
