What temperature and humidity does a ball python need?
This is the single most important number in ball python care. Warm side 88–92°F (31–33°C), cool side 78–80°F (26–27°C), with humidity around 50–60%, higher (65–75%) during shed. Everything else — appetite, shedding, activity — follows from getting this right.
Target temperature
- Warm side / basking
- Warm side 88–92°F (31–33°C)
- Cool side
- cool side 78–80°F (26–27°C)
- Humidity
- 50–60%, higher (65–75%) during shed
- Lighting
- Low UVB optional; a clear day/night cycle
Why a gradient matters more than one number
A ball python cannot choose a temperature if you only give it one. Provide a warm end and a cool end so it can move between them — that behaviour is how it regulates its own body temperature. Measure both ends with a digital probe; the stick-on dial gauges sold in pet shops are unreliable.
How to control it
- Heat: use a thermostatically controlled heat source. An unregulated heat source is the single most common cause of burns in captive reptiles.
- Humidity: adjust substrate, water surface area and ventilation rather than just misting. Misting spikes humidity briefly and then drops it again.
- Measurement: digital probes at animal level, not on the wall above it.
- Night: most species tolerate a night drop. Check what your species needs rather than heating 24 hours a day.
Species target: Warm side 88–92°F (31–33°C), cool side 78–80°F (26–27°C), humidity 50–60%, higher (65–75%) during shed. Low UVB optional; a clear day/night cycle.
Signs your numbers are off
- Too cold: a ball python that stops eating, stays hidden and becomes lethargic.
- Too hot: an animal that permanently sits at the cool end, gapes or avoids the basking spot entirely.
- Humidity wrong: shedding problems, or a constantly damp enclosure that never dries out.

How often do you feed a ball python?
Adults every 10–14 days, juveniles every 7–10 days, hatchlings every 5–7 days. Their appetite is sensitive to temperature and cover, so a sudden refusal usually points to the enclosure rather than illness.
What humidity does a ball python need?
Aim for 50–60% as a baseline and raise it to around 65–75% while they are in shed. Chronic low humidity is the usual cause of stuck sheds and stuck eye caps.
Is a heat mat enough?
A mat can provide a warm spot but will not raise ambient air temperature. Overhead heat (a halogen bulb or ceramic heat emitter) with a thermostat gives a more natural gradient. Whichever you use, it must be thermostatically controlled.
