What temperature should a ball python be?
A ball python needs a warm spot of around 31–32°C (88–90°F) and a cool end of 26–28°C (78–82°F), with a smooth gradient between the two so it can move to the temperature it needs. Get the gradient right and thermostat-controlled, measure the surface with a probe rather than a stick-on dial, and most feeding and digestion problems settle down.
The numbers that matter
Aim for a warm spot of 31–32°C (88–90°F), the surface the snake rests on to digest, and a cool end of 26–28°C (78–82°F). That spread is the whole point: a ball python can't make its own heat, so it shuttles between the warm and cool ends to hold the body temperature it needs. A box that sits at one temperature throughout gives it nowhere to thermoregulate.
Build a proper gradient
Put the heat source at one end and leave the other unheated so a clear warm-to-cool gradient runs the length of the enclosure. Always control the heat source with a thermostat so the warm spot holds its target rather than creeping up and overheating the snake. Give the snake a snug hide at both the warm and cool ends so it never has to choose between feeling safe and being at the right temperature.
Measure the surface, not the air
Temperature is meaningless without the right measurement. Read the actual surface the snake lies on with a digital probe thermometer or an infrared temperature gun, not a stick-on dial gauge, which is slow and inaccurate. Check both ends so you know the real range, and keep an eye on the warm spot over time, since a bulb quietly ages or a thermostat slips and the temperature drifts before you notice.
Night-time and lighting
A mild night-time drop is fine, down to about 24°C (75°F), and most rooms cool to a safe temperature on their own. Avoid bright or coloured night bulbs, which disturb a nocturnal snake's sleep; if a room genuinely gets too cold, use a thermostat-controlled ceramic heat emitter that gives off no light. Watch for the signs of a too-cool setup: a snake kept below its range digests poorly, refuses food, and in bad cases regurgitates a meal it couldn't process.
When to see a vet
Temperature is a husbandry fix rather than a veterinary one, but see an exotics vet if a snake kept at correct temperatures still refuses food, regurgitates repeatedly, or shows lethargy, weight loss, or wheezing, persistent problems on a correct setup point to something beyond heat.
One reading rarely tells the story. What matters is whether it's an isolated blip or part of a trend, so look at recent weight, feeding intervals, shedding, temperature and behaviour together.
baskr keeps those records in one place and watches the pattern for you, so you can see whether something has genuinely changed with your ball python, before it becomes a problem.

What temperature should a ball python's warm spot be?+
Around 31–32°C (88–90°F) at the surface the snake rests on, held steady with a thermostat. Measure it at that surface with a digital probe or infrared gun, not the surrounding air or a stick-on dial.
What should the cool side of a ball python tank be?+
About 26–28°C (78–82°F). Keeping the cool end distinctly cooler than the warm spot gives the snake the gradient it needs to move between warm and cool and regulate its body temperature.
Do ball pythons need heat at night?+
Usually not. A drop to around 24°C (75°F) at night is fine and most rooms reach it on their own. Only add heat if the room gets genuinely cold, and use a light-free, thermostat-controlled ceramic heat emitter rather than a bright or coloured bulb.
Can a ball python be too cold?+
Yes, and it's a common cause of trouble. A snake kept below its range can't digest properly, so it refuses food and may regurgitate a meal. Confirm the warm spot holds 31–32°C (88–90°F) at the surface with a digital probe before assuming anything else.
