This is the most famous rainy season, vital for agriculture but intense for travelers.

In many tropical zones, rain follows a schedule—often clear mornings followed by heavy afternoon bursts.

The "rainy season" (often called the monsoon or wet season) varies significantly depending on where you are in the world. It is defined by a significant increase in precipitation compared to the rest of the year.

Countries like Japan, China, and South Korea have a specific early-summer rainy period. June and July.

Most climatologists reject a single global threshold. Instead, three primary methods define a rainy month:

  1. rainy season month
  2. /
  3. rainy season month
