Climate

Climate is the general weather pattern within a scenario in Roller Coaster Tycoon. Climate determaines how hot or cold, and how wet or dry the scenario's weather will be. Climate can affect a scenario's success, and should not be taken lightly.

Original Scenarios
The original scenario's in Roller Coaster Tycoon 1 introduces 3 climates: Warm, Cool and Wet, and Hot and Dry.

Warm
The "Warm" climate is the most common amounst the 22  original scenarios. The Warm climate features confortable tempetures, and moderate rainfall. The starting tempeture for a scenario using the Warm climate is 62F (17C). The Warm climate made it's first appearance in the "Forest Frontiers" scenario, and is used in 13 of the 22 original scenarios.

Cool and Wet
The "Cool and Wet" climate is the next most common climate.It features more rainfall, and cooler tempetures than the Warm climate. The starting tempeture for a scenario using the Cool and Wet climate is 55F (13C). This climate can sometimes hurt a park's success due to some guests refusing to ride outdoor rides while it is raining. It is sugguested while playing in a park that has the Cool and Wet climate, to try to build more indoor rides outdoors, and to build custom rides at least 40% underground(that way they count as an indoor ride so guests will go on them in the rain). The Cool and Wet climate made it's first appearance in the "Katie's World" scenario, and is used in 5 of the 22 original scenarios.

Hot and Dry
The "Hot and Dry" climate is the least common climate. It features less rainfall, and hotter tempeture's than the other two climates. The starting tempeture for a scenario using the Hot and Dry climate is 62F (17C). It is sugguested while playing in a park that has the Hot and Dry climate, try to build more water rides, as guests want to ride water rides even more than usual. The Hot and Dry climate made it's first appearance in the "Dynamite Dunes" scenario. It only appears 3 times in the original game, all of which are the desert themed parks.

Each Scenario's Climate
Here is every original scenario from RCT 1 and its respective climate.

Corkscrew Follies Scenarios
The same 3 climates appear in the Corkscrew Follies expansion pack for RCT1. All scenarios except Future World, Thunderstorm Park, and Utopia Park use the "Warm" climate. Future World and Utopia Park use the "Hot and Dry" climate. Thunderstorm Park uses the "Cool and Wet" climate(hence the name).

Cold
The 3 original climates return in the Loopy Landscapes expansion pack for RCT1 along with a new climate called the "Cold" climate. The cold climate is much like the warm climate except that the tempetures are signifigantly lower. The starting tempeture for a scenario that uses the cold climate is 48F(9C). The cold climate only appears 3 times in the Loopy Landscapes scenarios, and all 3 scenarios are Snow/Ice themed scenarios.

Here is every scenario within the Loopy Landscapes expansion pack and its respective climate.

Roller Coaster Tycoon 2
The same four climates were brought back into RCT 2. When a player is creating a scenario, he/she can pick from one of the four climates for the scenario. The player can also change the climate of a scenario unlike in RCT1. The player must select the scenario they wish to change from the list of scenarios in the main menu screen. Once the scenario is open on screen, the player must go to the save game option, and save the game. Then the player must return to the main menu and click on the toolbox, and select the "Convert Saved Game to Scenario" option. Then the list of saved games will pop up, and the player needs to select the file they saved the game as. Once that is done, the player will be taken into a scenario editor mode where he/she can tweek certain options in a scenario, one of them being climate. If a player creates their own scenario, the tempeture will always start at 62F (17C) regardless of the climate.

Roller Coaster Tycoon 3
More climates were introduced in Roller Coaster Tycoon 3, but some of them are themed climates. There is a mountain climate, a spooky climate, a jungle climate, and more. This makes a scenario more unique.

Roller Coaster Tycoon 4
As of August 10, 2013, nothing is know about climates in RCT4.

Trivia

 * In RCT1, the original pack contained more cool and wet scenarios than the expansion packs' scenarios combined, despite there only being 22 original scenarios and 64 expansion scenarios.
 * All "Real Parks" scenarios RCT2 used the Warm climate.
 * No matter what the climate is, the tempeture will never go below 32F(0C), and never above 90F(32C). Each climate has its own bounderies however.
 * For some reason, Megaworld Park has the "Cool and Wet" climate while it's prequel, Mega Park, had the "Warm" climate.
 * The Mega Park-Megaworld Park prequal-sequel is the only prequel-sequel to not have the same climate in both scenarios.
 * The tempetures in the "Warm" and "Hot and Dry" climates both start at 62F(17C).
 * The "far off worlds" scenarios most likely have the "Hot and Dry" climate because it does not rain on mars or other planets.
