How do I maintain the correct temperature in my blue-tongue skink's enclosure during winter?
Keep the basking side at 95–100°F (35–38°C) and the cool side at 75–80°F (24–27°C) for optimal winter conditions.
Temperature Gradient
Maintaining a gradient of 20–25°F (11–14°C) between the basking and cool sides is crucial. This allows your skink to self-regulate its body temperature by moving between the warm and cool areas.
Blue-tongue skinks are ectothermic, meaning they rely on external heat sources to regulate their body temperature. The gradient ensures they can thermoregulate effectively without overheating or becoming too cold.
- Set the basking area to 95–100°F (35–38°C).
- Maintain the cool side at 75–80°F (24–27°C).
- Use a gradient of 20–25°F (11–14°C) between the basking and cool sides.
Controlling Temperature
Use a heat lamp with a thermostat to control the temperature on the basking side. Ensure the lamp is positioned at a safe distance to prevent burns.
For the cool side, use a heat mat or a room-temperature area. Avoid using heat lamps on the cool side.
Monitor the temperature at the animal's level, not from above, to ensure accuracy.
- Use a heat lamp with a thermostat.
- Position the heat lamp 18–24 inches above the ground.
- Monitor temperature with a digital thermometer at the skink's level.
Humidity and Lighting
Maintain humidity levels between 40–60% during winter. Use a hygrometer to monitor humidity.
Provide a UVB light for at least 12 hours a day to support vitamin D3 synthesis, which is essential for calcium metabolism.
Use a combination of artificial and natural light to simulate the skink's natural environment.
- Keep humidity between 40–60%.
- Use a hygrometer to measure humidity.
- Provide 12–14 hours of UVB light daily.
Observable Signs
If the basking area is too hot, your skink may exhibit signs of overheating, such as open mouth breathing, panting, or lying on the cool side of the enclosure.
If the cool side is too cold, your skink may shiver, seek warmth under the basking lamp, or have reduced activity levels.
Monitor your skink's behavior and appearance daily to ensure the temperature is within the optimal range.
- Signs of overheating: open mouth breathing, panting.
- Signs of being too cold: shivering, seeking warmth.
- Monitor daily for signs of discomfort.

Related questions
How often should I check the temperature in my skink's enclosure?
Check the temperature at least twice a day, especially during the first few weeks after setting up the enclosure.
What should I do if the temperature in the basking area is too low?
Increase the heat lamp's wattage or move it closer to the ground, ensuring it's still at a safe distance from the skink.
How can I tell if the humidity is too low?
If the substrate feels dry and the air feels dry, the humidity is likely too low. Increase humidity by misting the enclosure more frequently.
