While crested geckos naturally come from rainforests and are adapted to warm and humid conditions, keeping the temperature of the enclosure of your pet crested gecko in the perfect range is very important because overheating can lead to a lot of health problems in crested geckos.

It is, thus, very important to know the ambient temperature range for crested geckos and to have all the required arrangements to maintain the enclosure temperature at the stable ambient level even if the temperature outside changes.

How Do I Make My Crested Gecko Tank Cooler?

In an ideal situation, you wouldn’t have to worry about keeping the enclosure of your crested gecko cool, because the natural environment of the room will be enough.

But ideal situations rarely happen. So, what can you do when the room in itself gets too hot? The following are some ways in which you can make the tank of your crested gecko cool on a hot summer’s day:

Way 1 – Regulate the temperature of the room.

The first and the easiest thing that you can try to do is to regulate the temperature of your room where the enclosure is kept.

You can do that by either switching on the air conditioner or fan or using a space cooler.

Regulating the temperature of the room where the enclosure of your crested gecko is kept will automatically make the surroundings of the enclosure, and thereby the atmosphere inside the enclosure, cooler than the temperatures of the hot day outdoors.

Way 2 – Power down the light and heat sources inside the tank.

Another obvious way to cool the tank of your pet crested gecko is to power down all the light and heat sources inside the tank.

If you have been using UV lights to arrange the lighting within the enclosure, it may be a good idea to switch those lights off. This will make the enclosure slightly cooler than before.

Way 3 – Spray the vivarium or tank with cool water.

As the water you spray starts evaporating from the tank, it will cool down the walls and surfaces of the enclosure.

Now, this one is a short-term and short-lived solution. So, while it works well as a quick relief from the heat, you cannot simply rely on spraying cool water inside the tank for the complete temperature regulation for your pet crested gecko’s enclosure.

Way 4 – Dampen the soil-based substrate.

This method will only work if you have soil-based substrate in the tank of your pet crested gecko. But if you do, then you simply need to dampen – not soak – the substrate with cool water.

While the topmost layer of the substrate will dry off quickly, the deeper layers will retain the coolness for quite some time.

This is, in fact, how crested geckos and almost all the ground and land-based animals in the wild cool themselves during hotter days: they dig into the layers of soil and lay down in the cooler layers.

Way 5 – Last resort, move the enclosure.

If nothing else seems to be working well, you may want to shift the enclosure of your pet crested gecko to a cooler room.

Usually, you will only have to resort to this if you don’t have an air conditioner in the room where the enclosure was originally kept.

More often than not, just switching the air conditioner on for some time quickly cools off the enclosure of the crested gecko.

What Temperature Is Too Hot For A Crested Gecko?

When the temperature of the enclosure goes above 75 degrees Fahrenheit, it becomes really hot for a crested gecko.

Some crested geckos may, sometimes, manage to tolerate temperatures up to 77 degrees Fahrenheit when exposed for a very short period of time.

But usually, any temperatures exceeding 75 degrees Fahrenheit for a prolonged period of time are considered to be too hot for crested geckos.

Prolonged exposure to temperatures close to 80 degrees Fahrenheit will start causing health problems such as dehydration, sunken eyes, and weakness in crested geckos.

So, always remember to not cross the threshold of 75 degrees Fahrenheit in the enclosure.

All being said and done, the temperature level of 80 degrees can be considered too hot for a crested gecko, because usually, crested geckos are resilient enough to handle temperatures between 75 and 80 degrees Fahrenheit for very short intervals of time.

But 80 degrees Fahrenheit is where the threshold of resilience ends for most crested geckos.

What Is The Ideal Temperature For a Crested Gecko?

There is no single precise accurate or ideal temperature for a crested gecko. But there is an ideal range of ambient temperature that needs to be maintained in the enclosures of crested geckos.

The range of temperatures between 72 and 75 degrees Fahrenheit during the daytime and the range of temperatures between 68 and 74 degrees Fahrenheit are ideally suitable for crested geckos.

However, it is always better to have a heat gradient in the enclosure of your pet crested gecko.

What this means is that you should not have a constant temperature of, say 74 degrees Fahrenheit, in each and every spot of the enclosure of your pet crested gecko.

68 and 74 degrees Fahrenheit is ideal

Instead, you should maintain a gradient of temperatures of the ideal range in the enclosure, such that the temperature of the coldest spot does not go below 72 degrees Fahrenheit in the daytime and 68 degrees Fahrenheit in the nighttime. Similarly, the hottest spot inside the enclosure should not go above 75 degrees.

This gradation of heat inside the enclosure provides the most ideal setup of temperature for your pet crested gecko.

This way, your crested gecko will be able to go to the colder spot when it wants to cool down, and it will be able to take a comfortable nap in the warm spot if it gets too cold – and the temperature thresholds at the coldest and hottest spots will ensure that your pet crested gecko does not get too cold or too hot.

What Happens If It Gets Too Cold?

As aforementioned, there is a range of temperatures that form the ambient range for crested geckos.

As long as the temperature of the enclosure of your pet crested gecko remains within the maximum and minimum threshold temperatures of that ambient range, your crested gecko will be comfortable and healthy.

The ways mentioned above will help you keep the temperature of the enclosure well below the maximum threshold. But what about the minimum threshold temperature? What if the tank of your pet crested gecko gets too cold?

Not to worry. You will simply need to arrange a heating system inside the enclosure of your pet and remove all the sources of cooling.

You must ensure that the temperature of the tank of your pet crested gecko does not get too cold, as that may induce a forced brumation and your crested gecko may become dehydrated, malnourished, and sick.

How to safely cool your reptiles


Regulating the temperature of the enclosure of your pet crested gecko is very important because the temperature of the tank will have a direct impact on the health of the crested gecko.

There are many artificial means that will allow you to maintain the temperature of the tank at a cooler level, such as air conditioning, switching off lights and heating devices inside the tank, and spraying the tank with cool water.

However, you should be mindful when cooling down the tank of your pet and not let it become too cold.
