Is 113 Degrees Fahrenheit Hot? What 45°C Heat Feels Like
Yes: 113°F (45°C) is extreme, dangerous heat.
113°F is hotter than your skin and 14.4°F (8°C) above normal body temperature, so the air adds heat to your body instead of removing it. Heat exhaustion and heat stroke can develop with prolonged exposure, exertion or humidity. Weather services treat temperatures like this as dangerous heat.

What Does 113 Degrees Feel Like?
In dry desert air, 113°F feels like standing in front of an open oven or a hair dryer. The air itself feels hot on your skin, a breeze brings no relief, and you sweat heavily even when sitting still. Sun-exposed surfaces such as car seats, steering wheels, metal railings, playground equipment and dark pavement get much hotter than the air and can burn skin.
Humidity makes it far worse because sweat cannot evaporate. The US National Weather Service heat index (“feels like” temperature) for 113°F is roughly:
| Relative humidity | Feels like (heat index) |
|---|---|
| 20% | about 117°F (47°C) |
| 25% | about 123°F (51°C) |
| 30% | about 129°F (54°C): “extreme danger” (125°F+) |
The heat index is calculated for shade; direct sunshine can make conditions feel hotter still.
113°F Compared With Other Temperatures
| Reference | Fahrenheit (°F) | Celsius (°C) |
|---|---|---|
| Average skin temperature (approx.) | 95°F | 35°C |
| Normal body temperature | 98.6°F | 37°C |
| Heat stroke (body temperature) | 103°F+ | 39.4°C+ |
| Air temperature on this page | 113°F | 45°C |
| Hottest temperature ever recorded (Death Valley, 1913) | 134°F | 56.7°C |
Health Risks of 113°F Heat
At 113°F (45°C) the body relies almost entirely on sweating to stay cool. Losing a lot of fluid and salt, or being unable to evaporate sweat in humid air, lets body temperature climb.
Who Is Most at Risk
- Older adults (65+), who regulate body temperature less effectively
- Infants and young children
- People with chronic conditions such as heart disease, diabetes, kidney or lung disease
- Outdoor workers and athletes
- People taking certain medications, for example some diuretics, blood pressure drugs and psychiatric medicines
- People without air conditioning or a cool place to go
Warning Signs
Heat Exhaustion
- Heavy sweating
- Cold, pale, clammy skin
- Fast, weak pulse
- Nausea or vomiting
- Muscle cramps, tiredness, headache
- Dizziness or fainting
Move to a cooler place, loosen clothing, apply cool wet cloths and sip water. Get medical help if symptoms get worse or last longer than an hour, or if the person is vomiting.
Heat Stroke (emergency)
- Body temperature of 103°F (39.4°C) or higher
- Hot, red, dry or damp skin
- Fast, strong pulse
- Headache, dizziness, nausea
- Confusion or unusual behavior
- Fainting or loss of consciousness
Heat Stroke Is a Medical Emergency
If someone shows signs of heat stroke, call emergency services immediately. While waiting, move them to a cooler place and lower their temperature with cool cloths or a cool bath. Do not give them anything to drink.
Medical disclaimer: This page is general information, not medical advice. If you or someone else feels unwell in the heat, especially with confusion, fainting or a very high body temperature, seek medical help right away. People with heart, kidney or other chronic conditions should ask their doctor how to stay safe and how much to drink during heat waves.

- Pakistan and northern India: pre-monsoon heat waves in May and June regularly exceed 45°C.
- North Africa: the Sahara regularly passes 45°C in summer.
- Inland Australia: parts of Western Australia, South Australia, New South Wales and Queensland exceed 45°C in many summers.
- Southern Europe: parts of southern Spain (around Seville and Córdoba), Italy and Greece can pass 45°C in severe heat waves.
- Canada: Lytton, British Columbia reached 49.6°C (121.3°F) in June 2021, Canada’s national record.

Staying Safe in 113°F Heat
When temperatures reach 113°F (45°C), taking serious precautions is essential for health and safety. The following measures can help reduce the risk of heat-related illness during extreme heat events.
Heat Safety Measures
- Stay indoors in air-conditioned buildings when possible
- Drink water regularly, before you feel thirsty; for outdoor work, about 1 cup (8 oz) every 15–20 minutes is a common guideline (no more than about 48 oz / 1.4 L per hour)
- Avoid direct sun exposure, especially between 10 AM and 4 PM
- Wear loose, light-colored, lightweight clothing
- Take cool showers or baths to lower body temperature
- Don’t rely on an electric fan alone: in air this hot it mostly blows hot air at you; use air conditioning or a cooling center
- Check on vulnerable friends and family members
- Never leave children or pets in vehicles, even briefly; the inside of a parked car gets much hotter than the outside air
Preparing for a 113°F Heat Wave
- Ensure your air conditioning system is functioning properly
- Identify public cooling centers in your area if you lack air conditioning
- Stock up on water and non-perishable foods
- Prepare a power outage plan (as electrical grids can be strained during heat waves)
- Have a communication plan with family members
- Create an emergency contact list including medical providers
- Keep a first aid kit specifically for heat-related emergencies
Environmental Impacts of 113°F Heat
When temperatures reach 113°F (45°C), numerous environmental consequences occur beyond human health impacts. These extreme temperatures affect infrastructure, ecosystems, and can create cascading environmental problems.
Infrastructure Impacts
- Power grid strain due to increased air conditioning usage
- Road damage from thermal expansion and buckling
- Rail tracks can buckle in extreme heat
- Airport operations affected (reduced lift for aircraft takeoff)
- Water supply systems stressed due to increased demand
Ecosystem Impacts
- Aquatic ecosystems stressed from higher water temperatures
- Increased wildfire risk due to dry conditions
- Crop damage and failure reducing agricultural yield
- Wildlife stress or mortality from inability to thermoregulate
- Plant stress leading to reduced growth and productivity
Frequently Asked Questions
Is 113 degrees Fahrenheit hot?
Yes. 113°F (45°C) is extreme, dangerous heat. It is hotter than your skin and 14.4°F (8°C) above normal body temperature, so the air adds heat to your body and sweating is the only way left to cool down. Prolonged exposure, exertion or humidity can quickly lead to heat exhaustion or heat stroke.
What does 113 degrees feel like?
In dry desert air, 113°F feels like standing in front of an open oven or a hair dryer: the air itself feels hot on your skin, sun-exposed surfaces such as car seats, metal and pavement can burn, and you sweat heavily even at rest. In humid air it feels much worse, because sweat cannot evaporate. At 30% humidity the heat index of 113°F is about 129°F (54°C).
Where is it 113°F outside?
113°F (45°C) is a normal summer high in Death Valley, California, and is reached in most summers in Phoenix, Arizona. It is common in July and August in Kuwait and southern Iraq, occurs in pre-monsoon heat waves in Pakistan and northern India, and is reached during severe heat waves in places such as southern Spain and inland Australia.
What is 113°F in Celsius?
113°F is exactly 45°C: (113 − 32) × 5/9 = 45. See the 113°F to °C conversion for the step-by-step formula and a °F to °C chart. (113°C, by contrast, is 235.4°F, far above boiling.)
How long can a person safely stay outside in 113°F heat?
There is no safe fixed time. It depends on humidity, sun, activity, hydration, age, health and acclimatization. Keep outdoor time short, rest in shade or air conditioning often, drink water regularly, and stop and cool down at the first signs of heat exhaustion such as dizziness, nausea, headache or heavy sweating.
