Does it mean that the weather will get warmer after Tomb-Sweeping Day?

After Tomb-Sweeping Day, it means the weather is getting warmer.

Generally speaking, after January and beginning of spring, the weather began to get warmer, but the feeling was not obvious. After the vernal equinox, the direct point of the sun crossed the equator and entered the northern hemisphere, and the northern hemisphere entered the summer half year, and the temperature rose rapidly. After Tomb-Sweeping Day, this change is more obvious. As the saying goes, "a spring rain is warm" is the truth.
