Monsoon Season, or Green Season, is a Season in the Shipwrecked DLC. 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 becoming longer. Dusk stays longer.
Wormwood will start to bloom during this season.
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. Lightning, while present, is less frequent than during Hurricane Season and Strong Winds do not occur. Frequent rain means that Mushrooms grow back quickly.
The rains in Monsoon Season come in waves. Each wave will increase the size of the puddle that will flood the areas. Using the Sandbags can permanently remove a puddle when done properly (see Sandbags and Flooding for more information)
If the player must venture into flooded zones, an Umbrella combined with a hat with a water resistance rating such as a Top Hat or Football Helmet will prevent the player from getting wet. Snakeskin Jackets and Hats are good and cheap solutions to combat Wetness if no high-end gear were found from X Marks the Spot treasure chests. Blubber Suits and Tar Suits are perhaps the best gear because they completely make the player immune to Wetness, however they do not protect from lightning strikes.
Poison Mosquitoes start to appear during Monsoon Season spawning in the flooded areas. Lureplants will also begin to spawn in this season, rendering player-made flooring very effective to combat both puddles and Lureplants.
Like in Spring, normal Bees become aggressive towards the player. Crabbit Dens collapse within the first days of this season. However, the Sharkitten Den opens up and a chance of Tiger Shark to spawn is the highest.
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.
