Monsoon Season, or Green Season, is a season from Don't Starve: Shipwrecked. It is equivalent to Spring. Monsoon Season is indicated with the world having bluish green tint. By default, it begins on day 37 and ends on day 58. During Monsoon Season, nights gradually become shorter with days and dusks becoming longer.
Rain during Monsoon Season causes patches of land to be flooded. The first days of monsoon seasons are relatively rain-free. However, as the season progresses, rain becomes more frequent and flooding worsens until most of the land is flooded during the end of the season. Still, lightning is less common than during Hurricane Season and Strong Winds are not present.
Mosquitoes start to appear during Monsoon Season.
Monsoon Season is followed by Dry Season. Long-term goal of Monsoon Season is to prepare for Dry Season in advance. It is more easily done within the first half of the season where flooding is not much of an issue and rains are not very frequent.
