The Sims 2: Seasons[edit | edit source]
Temperature in The Sims 2: Seasons is measured on a scale of -100 to 100. This scale is applied to indoor temperature, outdoor temperature, and Sims' internal temperature. Within that range, it is divided into five zones.
Indoor temperatures are comfortable unless a room is open to the outside weather. This can happen if there is no roof, or if a room contains a stairway to a rooftop deck, or if there is a gap in an exterior wall. Players should note that, while a gable on a gable roof is high enough to serve as one wall of a room, and wall coverings can be applied to it, the game does not consider it a wall when deciding whether a room is open to the outside. Sims who are at work, school, or at college classes are considered to be in a comfortable area.
The outdoor temperature is invisible, but does have some visible effects. Below -20, ponds freeze and snow may fall. If the outdoor temperature is cold or very cold, Sims may change into outerwear before going outside, and visitors, walk-bys, and townies may appear in outerwear. Outdoor temperature does not change during the day, but drops at night. It also drops during rain, hail, and snow. Reading the weather forecast in the newspaper or watching the weather channel on television may give some information about the outdoor temperature.
Swimming pools are heated, and are comfortable regardless of the temperature.
Internal temperature[edit | edit source]
When selected, a Sim, regardless of life state, has an internal temperature meter that resembles a small thermometer. This does not show the Sim's exact temperature, but does let the player see which zone it's in. When the Sim's temperature is in the comfortable zone, the meter is green, and is in the middle of the gauge. When the Sim becomes cold, the meter turns blue and drops. When he or she becomes hot, it turns red and rises. When the Sim becomes very cold or very hot, the meter will drop or rise again, and seem to glow.
Sims will also have visible reactions to being cold or hot. Cold Sims will occasionally shiver a little, and may appear "rosy-cheeked". Very cold Sims will shiver more often and more severely, and their skin will have a bluish tone. Hot Sims will occasionally show "it's too hot" reactions, such as wiping their brows, and their skin may appear to be slightly red. When Sims become very hot, their "it's too hot" reactions will be more frequent and severe, and their skin will be very red. This resembles sunburn and is often assumed to be sunburn. Players should note that the game may lag when a Sim's skin changes tone as a result of internal temperature.
Sims will freeze when their internal temperature reaches -100, and will collapse from heatstroke if it reaches 100. Sims will not die from this unless their hunger motive becomes completely depleted before they recover or are revived. However, there is a chance that seriously overheated Sims will spontaneously combust. (The Seasons patch makes this less likely.) It has been reported that other life states cannot freeze, suffer heatstroke, or combust, even if they can reach the necessary temperatures.[confirmation needed]
Only normal Sims can experience the full range of internal temperatures. Pets do not have internal temperatures, but outdoor temperatures and weather will affect how appealing the outdoors are to them. Servos and zombies have internal temperatures that never vary. Other life states have their own temperature ranges, which stop short of one or both extremes.
|Alien||-100||80||Presumably includes first-generation alien-Sim hybrids.|
|Zombie||0||0||Zombies are totally unaffected by the surrounding temperature.|
|Vampire||-80||100||More Awesome Than You has a mod which raises the minimum to -25, which is toward the low end of the comfortable zone.|
|Servo||0||0||Servos are totally unaffected by the surrounding temperature.|
|Werewolf||-50||100||They can become cold, but not very cold. It is likely that these limits only apply while the werewolf is transformed.|
|PlantSim||-100||50||They can become hot, but not very hot.|
|Bigfoot||0||94||They are impervious to cold, but can become very hot.|
The Sims 3: Seasons[edit | edit source]
Temperature in The Sims 3: Seasons uses real-world scales, and can be set to display in either Fahrenheit or Celsius. As in its predecessor, temperature has positive or negative effects on Sims and causes visual changes to the environment.
|Hot||32°C / 90°F||37°C / 99°F|
|Warm||21°C / 70°F||31°C / 88°F|
|Mild||10°C / 50°F||20°C / 68°F|
|Cool||0°C / 32°F||9°C / 48°F|
|Cold||-17°C / 0°F||0°C / 32°F|
Effects on Sims[edit | edit source]
Sims will not be affected by temperatures in the mild range, as that is considered to be the comfortable range. When the temperature climbs into the warm or hot ranges, Sims will receive moodlets related to high temperatures. If the temperature gets too high, Sims may suffer from sunburn, or even spontaneous combustion. Likewise, when the temperature falls into the cool or cold range, Sims will receive moodlets related to low temperatures. Sims who are exposed to low temperatures for too long may become sick, and may even freeze.
Effects on the environment[edit | edit source]
As mentioned earlier, the temperature will also affect the environment. For example, temperatures in the hot range will cause a heat haze to be visible. Likewise, when the temperature is in the cold range, frost will gradually form, and lakes and ponds will freeze over. Accumulated snow will not melt as long as the temperature remains in the cold range, but lakes, frost, and snow will start to thaw as soon as it rises out of this range.
The Sims 4: Seasons[edit | edit source]
Like The Sims 2, The Sims 4: Seasons does not use real-world temperature units. Sims that are too cold can warm themselves up by using campfires[TS4:OR], heat lamps[TS4:DO], fireplaces, or by putting on cold weather outfits. However, they can overheat if they're not careful. If they get too warm, they can cool down by swimming, using lawn water slides[TS4:BS], hydrating, standing under a ceiling fan, or putting on hot weather outfits.
At extreme temperatures such as "Heatwave" or "Freezing", Sims will feel temperature effects indoors. There is a chance for them to burn or freeze to death unless they wear hot/cold weather outfits at all times, or there is an active thermostat on the lot. Sims who are at work, school or an otherwise off-world place are considered to be indoors with an active thermostat.
Temperature levels and effects[edit | edit source]
There are six different temperature levels, ranging from "Freezing" to "Heatwave":
|Range||Effects on Sims||Effects on the environment|
|Heatwave||Sims will automatically change into hot weather outfits both indoors and outdoors.||A heat haze will appear on the screen when the player zooms out. During the day, overall lighting levels are brighter and more intense.|
|Hot||Sims will automatically change into hot weather outfits when they go outside.||N/A|
|Warm||Comfortable range for Sims.||N/A|
|Cool||Comfortable range for Sims.||N/A|
|Cold||Sims will automatically change into cold weather outfits when they go outside.||Condensation will appear from Sims' mouths and on windows and doors.|
|Freezing||Sims will automatically change into cold weather outfits both indoors and outdoors. During blizzards, Sims are seen shivering, cowering, and occasionally slipping over the ground.||Condensation will appear from Sims' mouths as well as on windows and doors. Lakes and rivers will also freeze over.|
