Since Iguanas evolved to survive in such extreme conditions, They must be maintained in similar situations when kept out in nature. To ensure that your Iguana is healthy and active, you must keep proper temperature gradient in their tank to rest and cool down when required.

Ideal Temperature For An Adult Iguana

Adult Iguanas can tolerate slightly lesser heat than the younger Iguanas. This is due to their larger bodies, which lets them hold on to the heat much longer than small Iguanas. Because the Iguanas aren’t growing as rapidly, they do not require more energy to boost their metabolism.

The Basking Area temperature range from 95degF to 100degF. The Non-Basking Zone temperature range from 90degF to 90degF.

Ideal temperature For A Juvenile Iguana

Juvenile Iguanas are usually somewhere between adults and infants in terms of requirements for heat. Even though the growth rate has dropped, they need heating to boost their metabolism. The body mass of their bodies remains at a lower level, and they’re less effective in maintaining your body’s temperature. Set same temperature as stated above for adults.

Ideal Temperature For A Baby Iguana

Baby Iguanas need to keep an elevated temperature to remain healthy and active. They are young Iguanas who find themselves at a stage in their lives when there is rapid development.

To help support these growth rates, Iguanas must increase their metabolism by being warm throughout the day. Because baby’s Iguanas are so small, They aren’t in a position where they can hold sufficient body heat. So they must have access to an energy source late at night if possible.

Their Basking Area should range from 95degF to 110degF Whereas, Non-Basking Area from 90degF up to 90degF

Iguana Temperature at night

Iguanas can tolerate lower temperatures at night. In their natural habitat in their native Australian desert, the temperatures during nighttime can drop substantially. This is the case in every desert, where temperature fluctuations of 30-40 degrees daily and at night aren’t uncommon. Since they can withstand this, it’s possible to maintain your Iguana’s habitat at your home’s temperature in the evening.

What temperature is terrible for Iguanas?

Temperatures that exceed 110 degrees Fahrenheit can be dangerous for the health of Iguanas. At temperatures of 50 degrees, Iguanas feel tired and sluggish. At around 50 degrees, Iguanas can become inactive.

It is suggested to turn off the lamps for basking and those UVB light sources at night so that these animals can rest comfortably in the dark. A timer on a digital plug, such as Zilla Reptile Habitat Lighting And Terrarium Heat Power Centre, can assist in turning the lights off and on during the night and day cycle.

If you decide to warm your vivarium during the evening or not depends on the temperature in the area. Reptiles can handle temperatures as low as 65degF and possibly higher if temperatures fall under 65 degrees. It is imperative to install a heating system.

Since there isn’t a requirement for lighting, it could disrupt their sleep and wake cycles. To warm their living spaces, opt for ceramic heaters for tanks, and we recommend ceramic. Once you have found one and set the temperature, you can set it to 65 degrees and 90 degrees, with the ideal temperature of 21 degrees Celsius (90degF).

It is essential to have a thermostat that can be adjusted to keep the temperature within the desired range. If temperatures in the evening are above 65 degrees Fahrenheit, you do not need the use of vivarium heating at night. Although some may advise you to use blankets or duvets to help keep the pet cozy, although it may be beneficial, make sure they don’t block ventilation to avoid the accumulation of humidity.

How To Tell If Your Iguana Is Getting Enough Heat?

Iguanas can regulate body temperature. If their body temperature is above the limit for optimal temperature when they’re relaxed and reclining, they’ll open their mouths to release body heat. This behavior of Iguanas is called gaping. You can try different temperatures in the basking area and determine if your Iguana is shaking. In the absence of this, it may be because the Iguana isn’t getting enough warmth within the basking zone.

Signs of Overheated Iguana

If the conditions outside are hot and dry, this could affect the temperature in your aquarium. This means that your Iguana could get dehydrated from the extreme heat. To determine if the Iguana is hot, check if it’s staying away from the basking area for the majority of the duration.

Other signs of an overheated animal to watch out for include dry heaving, breathy breath, and weight loss. You may bathe it in case you think your Iguana could be overheating. If you are still experiencing symptoms, it is worth visiting the vet.

How To Setup A Temperature Gradient Inside The Iguana’s Tank?

It was mentioned before that your terrarium must include a place to unwind and a spot for cooling your Iguana. Establishing an overall temperature gradient within the enclosure is essential so that the Iguana can regulate body temperature by moving between cool and hot zones as needed.

Different tools can assist you in creating your temperature gradient. However, it’s essential to choose the correct tools and learn how to use them correctly. This is a brief outline of the most commonly used tools that could be an excellent choice to utilize.

Heating bulb

Most Iguana owners utilize the heating bulbs starting from the top and ending at the bottom to create a peaceful space for their pets.

Ceramic bulbs which emit radiant heat are the type of bulb that is excellent for heating during the evening. The most common mistake people make is to place the bulb in the basking inside the middle of the enclosure. Instead, it should be set on the other side of the square, from top to bottom.

So you’ll be able to ensure there’s sufficient room between your basking zone and the zone for cooling down. The bulbs that produce illumination in the Iguana enclosure come in various watts, including 60 Watts, 75 watts, or 100 Watts.

Suppose you’re hoping to generate more heat, select bulbs with higher Watts. For instance, 100-watt bulbs generate more excellent heat than bulbs with 60 watts. There’s a second aspect to think about when choosing the power. When a lamp’s brightness has been dimmed greater its wattage, the dimmer it appears.

For instance, 60-watt lamps with 50 watts of power are more attractive than 100-watt bulbs cut down to 50 watts. If you’re trying to make your space appear brighter, select 60-watt bulbs instead of their 100-watt counterpart.


The thermostat can be described as a piece of equipment that regulates the terrarium’s temperature to improve the quality of life for Iguana owners easier. The thermostat comes with sensors that determine the current temperature and control the heating. Two types of thermostats can be used in the Iguana enclosure.

Select the best one for your requirements according to the bulb you’re using. If you’re using bulbs that produce light, consider using the dimming feature on thermostats. A thermostat that dims will release energy gradually, which means that it will gradually increase the brightness or dim the lighting within your yard.

It is, however, a pulse thermostat, which, as the name implies, transmits energy using the form of pulses. This type of thermostat is perfect for those who have bulbs that don’t emit light.

Heating mats

They also make a great alternative to creating an incline in temperature within an Iguana enclosure. They emit infrared light, which creates uniform heat throughout an area. But, setting the mat in conjunction with some of the other sides inside the Iguana cage can cause a smooth temperature gradient across the enclosure.

10 Sources Of Heat For The Iguana’s Tank

If you live in regions with colder winters, It is essential to use different heating sources to keep your Iguanas warm. The most popular heating options for terrariums include:

  1. Infrared lamps
  2. Incandescent bulbs (halogen basking lambs)
  3. Ceramic heaters
  4. Mercury vapor lamps
  5. Lamps that contain metallic halides
  6. Pads or mats for heating
  7. The scorching heat can be deadly
  8. Strips or cables for heating
  9. Space heaters
  10. Reptile deep heat projector


The right temperature for your terrarium is vital to your and your pet’s overall health and wellbeing. The correct temperature gradient for your vivarium can be a challenge, but the tips above can make it easier.
