The Complete Leopard Gecko Temperature Guide
Leopard gecko temperatures made simple: warm hide 88-92°F, cool side 70-77°F, the right heating methods, and the common mistakes that cause illness.
The Complete Leopard Gecko Temperature Guide
As ectotherms, leopard geckos cannot generate their own body heat. They depend entirely on their environment to digest food, fight infection, and stay active. Getting temperatures right is non-negotiable - see our full Leopard Gecko care guide for the rest of their housing and diet needs.
The Thermal Gradient
Leopard geckos need a range of temperatures so they can thermoregulate by moving between warm and cool zones:
- Warm hide (belly heat): 88-92°F
- Ambient warm side: 80-84°F
- Cool side: 70-77°F
Heating Methods
Under-tank heaters (UTHs) connected to a thermostat are the gold standard for belly heat. Never run a UTH without a thermostat. They can reach dangerous temperatures and cause burns. Overhead heat panels work too, but belly heat is preferred for this species.
What NOT to Do
- Hot rocks: uneven heat distribution causes burns
- Coil CHE (ceramic heat emitter) without thermostat: fire risk
- No cool side: prevents thermoregulation and causes chronic stress
Measuring Temperatures
Use an infrared (IR) temperature gun to check surface temps, especially on the warm hide floor. Digital thermometers with probes work for ambient air temps. Check temps at different times of day. Leopard geckos are nocturnal, so night temps matter too.
Night Temperatures
Temperatures can safely drop to 65°F at night, mimicking natural desert conditions. If your home drops below this, use a ceramic heat emitter (no light, just heat) on a thermostat.
Nail your temperatures and your leopard gecko will be a healthy, active, long-lived companion. Correct temperatures also directly support healthy sheds - see our complete guide to reptile shedding for how the two connect.
