The Dry Season (also known as Volcano Season) is one of the four Seasons in the Shipwrecked DLC. It is indicated by the world having yellow/orange tint, similar to Summer in Reign of Giants DLC. By default, the first Dry Season begins on day 58 and ends on day 74. During the Dry Season, nights are very short, and dusk starts long but becomes shorter in length as the season progresses.
Within the first days of the season, areas that were Flooded during Monsoon Season begin to dry up. The temperatures soon rise to the point where Overheating becomes a major issue, especially during the middle of the season. Overheating is not as severe compared to Reign of Giants DLC's Summer season, and fires do not spontaneously start. In addition, overheating is usually not an issue during the first and last two days of Dry Season. Some plants like Bamboo can wither, making them non-functional unless treated. Limpet Rocks can wither as well.
During Dry Season, the ocean is calmer with fewer waves. The waves get less frequent towards the end of the season. Fishing with a Trawl Net during Dry Season will yield the greatest variety of catch, including a chance to obtain Obsidian.
Dry Season is followed by Mild Season.
Soon after the flooded areas have dried up completely, the Volcano will start to erupt. Tremors occur three times before each eruption, giving slightly more than half of a day to prepare. When the volcano erupts, Dragoon Eggs rain down from the sky, each briefly showing a shadow where it will land, and targeting areas within and slightly beyond the player's view. Eruptions can be delayed by offering appeasement to the Volcano Altar of Snackrifice. With regular appeasement one can go the entire Dry Season with no eruptions, though this requires frequent travel to or living within the Volcano.
Note that even if Volcano is fully appeased - the number of warning tremors does not reset. Therefore if for example Volcano was initially appeased right after the third tremor happened - once the delay is exceeded, the eruption will commence without any warning tremors at all. This means that one cannot rely on tremors to time the appeasements.
Since Dragoon Eggs tend to cause havoc, it is recommended to leave an established base and retreat to a location with no or few combustible resources. The best places for this are barren landscapes and shallow ocean.
Ocean is recommended more during the middle of the season where overheating is a major problem and wetness can provide emergency cooldown. The ocean is a less viable option during the last days of the season when the frequency of eruptions rises dramatically. Fortunately by that point, overheating is less of a problem.
Another strategy, requiring the player to prepare beforehand, is to appease the Volcano by offering appeasement to Volcano Altar of Snackrifice. Trapping a Crabbit or a Bird is a source of renewable appeasement while trinkets can be used for emergency measure. Building a sub-camp near the volcano with bird/crabbit traps is a good idea since if an eruption happens, the player's main camp won't be at risk of being destroyed. This strategy is valuable for the last days of Dry season where eruptions happen extremely frequently and the player needs more time to prepare.
Alternatively, a base can be built inside the Volcano. Eggs provide a high appeasement value, and can be obtained using a bird in a Birdcage, by feeding it Cooked Monster Meat. Monster Meat can be obtained by killing Dragoons or planting Spider Eggs inside the Volcano and killing the spawning Spiders. This can be efficiently accomplished by use of an Elephant Cactus monster farm. Transplanting Jungle Turf and Snakeskin Rug into the biome allows for the creation of a fully sustainable base. An Ice Box paired with two Thermal Stones is recommended to prevent overheating. Destroying or avoiding Dragoon Dens near the base is also advisable, due to the Dragoons' tendency to set structures on fire if aggroed. Ice Flingomatics can provide some protection from Dragoons and prevent transplanted Plants from withering.
For dodging, it is best to stay on a Beach or Shallow Ocean, or any light-coloured Turf. The Ashes that cover the screen during an eruption may hinder vision and reactivity towards the shadows produced by falling Dragoon Eggs, which makes places like the Magma Turf a bad idea with its dark color even though it doesn't have the risk of burning resources. Thus, a sacrificial Beach for volcanic eruptions may be needed in case the volcano hasn't been found yet. It is also a good idea to wear Armor while dodging Dragoon Eggs on land. Wearing a Log Suit with maximum Health will allow any character to survive a direct hit. Combining a stronger armor with a helmet (such as a Football Helmet) will allow surviving multiple hits. For the eruptions happening at night, a Campfire or Endothermic Fire can be built for protection from Charlie and to be able to see the shadows of falling Dragoon Eggs. However, these can be destroyed if any eggs strike near them. While Torches can be used, they do not provide a large light radius. Therefore, the best option is to use a Bottle Lantern or a Miner Hat. Landing Dragoon Eggs will sometimes form Lava Pools, which provide light with a fairly large radius, allowing the light source to be unequipped to save their durability. Obsidian Fire Pits are another alternative for providing light during a night eruption, a fully fueled Obsidian Fire Pit provides light for a large area. However, this may be a bit risky, since if the player gets close to the fire pit, landing Dragoon Eggs can destroy the Obsidian Fire Pit, eliminating the light source.
