Important: 31°C is NOT a Fever Temperature
Some searches mention "31 c to fever" - this is a misunderstanding. 31°C (87.8°F) is not a fever temperature.
Actual body temperature ranges:
- Normal body temperature: 36.5-37.5°C (97.7-99.5°F)
- Fever: 38°C+ (100.4°F+)
- 31°C would indicate severe hypothermia, not fever
Negative 31°C Conversion
Some people search for "minus 31 c to f". Here's that conversion:
-31°C in Fahrenheit is:
-23.8°F
-31°C (-23.8°F) is extremely cold. This temperature is:
- Found in polar regions or during extreme cold snaps
- Dangerous without proper protective clothing
- Can cause frostbite on exposed skin in minutes
- Requires special precautions for vehicles and infrastructure

FAQs
Is 31°C hot or cold?
31°C (87.8°F) is generally considered warm to hot. Most people would describe it as:
- Warm summer weather in temperate climates
- Pleasant for outdoor activities in dry conditions
- Potentially uncomfortable when combined with high humidity
- Typical beach weather in many vacation destinations
Perception can vary based on acclimation, humidity, and personal preference.
What is negative 31 Celsius in Fahrenheit?
Negative 31°C (-31°C) equals -23.8°F. This is extremely cold and dangerous without proper protection.
At -31°C (-23.8°F):
- Exposed skin can develop frostbite in less than 30 minutes
- Heavy winter clothing is essential for survival
- Vehicles require special antifreeze and may have starting issues
- Outdoor activities are limited without specialized equipment
Is 31°C a fever temperature?
No, 31°C is not a fever temperature. This is a common misunderstanding from temperature conversion searches.
Actual body temperature ranges are:
- Normal body temperature: 36.5-37.5°C (97.7-99.5°F)
- Fever: 38°C+ (100.4°F+)
- 31°C would indicate severe hypothermia, not fever

What should I wear at 31°C?
At 31°C (87.8°F), recommended clothing includes:
- Tops: Light t-shirts, tank tops, or breathable blouses
- Bottoms: Shorts, skirts, or light trousers
- Footwear: Sandals, breathable shoes, or flip-flops
- Accessories: Sun hat, sunglasses, and sunscreen

Is 31°C good for swimming?
31°C air temperature is excellent for swimming. For reference:
- Air temperature: 31°C (87.8°F) - warm and comfortable
- Pool water temperature: Ideal is 26-28°C (79-82°F)
- Ocean temperature: Varies by location, typically 20-27°C (68-81°F)
The warm air temperature makes getting in and out of the water comfortable, and the contrast with cooler water can be refreshing.
How do I convert 31°C to Fahrenheit in my head?
Here's a quick mental calculation method:
- Double the Celsius value: 31 × 2 = 62
- Subtract 10%: 62 - 6.2 = 55.8
- Add 32: 55.8 + 32 = 87.8°F
This gives you the exact conversion of 87.8°F.
For a rough estimate: Double it and add 30 (31×2=62, +30=92°F), which is close but slightly overestimates.
