Temperature

Temperature is a feature that was introduced in The Sims 2: Seasons and incorporated into The Sims Castaway Stories. It is also present in The Sims 3: Seasons and The Sims 4: Seasons.
==The Sims 2: Seasons==
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.
Range 	Minimum	Maximum
Very Hot 	70 	100
Hot 	30 	70
Comfortable	-30 	30
Cold 	-70 	-30
Very Cold 	-100 	-70
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===
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.
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.
Life state	Minimum	Maximum	Notes
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==
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.
Range	Minimum 	Maximum
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
If using Testing cheats to change the temperature, the temperature still cannot go under 0°F (-17°C, as the text field does not accept negative Fahrenheit values), but can accept very high temperatures, going up to 2,147,483,647°F (1,193,046,528°C). Such very high temperatures do not seem to increase a Sim's body temperature any faster than a regular heatwave.
===Effects on Sims===
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.
A Sim who has been freezing heavily ("Teeth Chattering") for a considerable amount of time, can freeze solid and lay on the ground. They can be thawed by nearby Sims, firefighters, and even mail carriers, but will die if left to themselves in such a frozen state for 3 hours.
Neither ocean swimming or a witch's Ice Blast seem to affect a Sim's body temperature, despite that Sims affected by an Ice Blast will shiver heavily or occasionally freeze solid in a non-lethal standing pose.
===Effects on the environment===
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==
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, heat lamps, radiators, space heaters, 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, hydrating, standing under a ceiling fan, turning on an air conditioner, or putting on hot weather outfits.https://twitter.com/SimGuruEmory/status/1000452435528237056
The only way to prevent or protect them from this is that The Sim must Have The Heat/Cold Acclimation and Iceproof/Heatproof from the rewards store. The Player can also disable this is the game options.
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.
Vampires (from The Sims 4: Vampires) and ghosts are immune to temperature changes (although they can be harmed in the sunlight unless they have Sun Resistance perk). They will not automatically change into hot or cold weather outfits, as they do not need them. Servos are not affected by temperature changes.
===Temperature levels and effects===
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.
