The Japanese rainy season usually lasts from early June to mid-July, just before it starts to become unbearably hot and humid in summer.
It often rains non-stop all day.
The kanji in this word are:
梅 = plum
雨 = rain
According to Wikipedia, this name comes from China. When plums begin to fall during this period, the moisture evaporating from these plants was believed to transform into rain.
