Ball Python Temperature & Humidity Guide
Last updated: · Reviewed against sources listed below
Ball python humidity should stay around 50–70%, rising to 60–65% during shed, with a basking area of 88–92°F, a cool side of 75–80°F and nights no lower than about 72°F. Enter your readings in the checker above to see what needs adjusting.

Temperature gradient
Like all reptiles, ball pythons regulate their body temperature by moving between warm and cool areas. After a meal they often spend more time on the warm side to digest; before a shed they may prefer the cool, humid side. Give them the full range with a hide at each end.

Keeping humidity right
Low humidity is the most common ball python husbandry problem, and it shows up as stuck shed, especially around the eyes and tail tip. To raise humidity:
- Use a moisture-holding substrate such as coconut husk or cypress mulch, damp at the bottom.
- Add a humid hide with damp sphagnum moss.
- Use a large, heavy water bowl on the warm side, where evaporation is higher.
- Cover part of any mesh top with foil tape or a solid panel.
Humidity that is too high, with soaked substrate and no airflow, can cause blister-like skin problems and respiratory infections. Aim for damp, not wet.
How to measure
Use a digital thermometer with a probe at the floor under the basking area and inside the cool hide, and check surfaces with an infrared thermometer. Place a digital hygrometer at snake level in the middle of the enclosure. Analog dials are often inaccurate by several degrees or percentage points.
Choosing a heat source
Overhead heat sources such as halogen bulbs, deep heat projectors and radiant heat panels warm both the air and the surfaces below, much like the sun. Radiant heat panels are popular for ball pythons because they give gentle, even heat without much light and dry the air less than some bulbs. Heat mats under a glass tank warm only the floor and can overheat without a thermostat.
Whatever you choose, run it on a thermostat with the probe where your snake rests, and use a guard around any bulb inside the enclosure. Snakes can coil around an unguarded bulb or heater and suffer serious burns without moving away.
Seasonal changes and feeding
Many ball pythons eat less in winter, even with steady temperatures, and some adult males stop eating for weeks or months. Keep temperatures and humidity stable year-round, especially at night when rooms cool down, and weigh your snake regularly.
See a reptile vet if your ball python wheezes or breathes with its mouth open, has bubbles or mucus at the nose, has repeated stuck shed over the eyes, or is losing weight.
Frequently asked questions
What humidity does a ball python need?
Keep humidity around 50–70%, and raise it to about 60–65% when your snake is in shed (cloudy eyes, dull skin). Too damp for too long can cause skin blisters. A humid hide and moisture-holding substrate make this easy. Avoid soaking the enclosure, because wet substrate with poor airflow causes skin problems.
What temperature should a ball python tank be?
Aim for a basking area of 88–92°F, a cool side of 75–80°F and nights no lower than about 72°F. Measure at floor level with a digital probe, and run every heater on a thermostat. Our checker above tells you what to adjust if a reading is off.
