Winter is a sensitive time for turtles. Cold weather changes how turtles behave, eat, and stay healthy. Many turtles slow down during winter, and some even enter a natural resting phase. If winter care is not done correctly, turtles can easily fall sick. This winter care guide for turtles explains everything a beginner needs to know to keep turtles safe, warm, and healthy during cold months.
It focuses on indoor care, outdoor safety, heating, lighting, feeding, and health problems that often happen in winter. For new turtle owners who want year-round guidance beyond winter care, How to Care for Your Turtle? Complete Guide to a Happy and Healthy Pet offers a complete beginner-friendly overview.
1. How Winter Affects Turtles?
Turtles are cold-blooded animals. This means their body temperature depends completely on their surroundings. When winter starts and temperatures drop, turtles naturally become slow. Their movement reduces, digestion becomes weaker, and their immune system also slows down. In captivity, turtles cannot choose the perfect environment like they do in nature, so owners must control their habitat carefully.
If a turtle stays cold for long periods, it may stop eating, become weak, or develop infections. Stable warmth is the most important part of winter turtle care.
2. Do Turtles Hibernate During Winter?
Many people believe turtles hibernate like bears, but turtles do something different. Turtles go into a state called brumation. Brumation is a resting phase where turtles reduce activity, eat very little or not at all, and stay still for long periods. Their breathing and heart rate slow down, but they are not fully asleep.
Not all turtles should brumate. Most pet turtles are healthier when kept active during winter using proper heat and light.
3. Which Turtles Should Not Brumate?
Some turtle species naturally brumate in the wild, but captivity changes many things. Tropical turtles should never brumate because they come from warm regions and cannot tolerate cold. Even turtles that brumate in nature may not need brumation in captivity.
For beginners, it is always safer to avoid brumation. Keeping turtles warm and active during winter reduces risk and prevents serious health problems.
4. Indoor Winter Care for Pet Turtles
Most pet turtles spend winter indoors. Indoor winter care focuses on keeping the temperature stable, providing correct lighting, and maintaining a clean environment. Room temperature alone is not enough for turtles. Artificial heating and lighting are required every day.
Never assume your turtle is fine just because the room feels warm to you.
Proper indoor winter care becomes easier when the enclosure is designed correctly, and beginners can refer to How to Create the Best Tank for Your Aquatic Turtle to understand ideal tank size, heating, and layout.
Correct Temperature for Turtles in Winter
Temperature control is critical during winter. If the enclosure becomes cold, turtles cannot digest food properly. Poor digestion leads to infections and weakness. For aquatic turtles, the water temperature should stay between 24°C and 28°C, while the basking area should be warmer, around 30°C to 32°C, so the turtle can dry its shell completely after swimming.
For land turtles, the daytime basking area should remain between 30°C and 35°C, while the cooler resting area should stay around 22°C to 26°C to allow natural temperature regulation.
At night, temperatures can drop slightly but should never fall below 20°C for most pet turtles. Sudden temperature drops are dangerous and can cause respiratory infections and loss of appetite. Temperature must remain stable day and night, especially during winter months when room temperatures change quickly.
Importance of Heat Lamps in Winter
Heat lamps help turtles warm their bodies and stay active. During winter, heat lamps should remain on daily for proper hours. The basking area should be warm enough for turtles to dry their shell completely after bathing or swimming.
A dry shell prevents fungal growth and shell rot. Turning off heat lamps during winter nights can be harmful unless the enclosure stays warm.
Why UVB Light Is Essential Even in Winter?
UVB light is often ignored during winter, but it is extremely important. UVB helps turtles absorb calcium, which keeps their shell and bones strong. Without UVB, turtles can develop soft shells, weak bones, and serious long-term health problems.
Even in winter, turtles need about 10 to 12 hours of UVB light every day. Sunlight through windows does not provide UVB. Artificial UVB lamps are necessary all year.
Winter Tank Setup for Aquatic Turtles
Aquatic turtles are very sensitive to cold water, so the tank setup becomes extremely important during winter. The tank must be large enough to hold stable heat and clean water. For small or juvenile aquatic turtles, a tank of at least 75 to 100 liters is required. For adult aquatic turtles, the tank should be 200 liters or more, depending on the turtle’s size. A general rule is that the tank length should be at least 5 times the turtle’s shell length, and the water depth should be 1.5 to 2 times the shell length so the turtle can swim freely without stress.

During winter, tank water must stay warm and clean at all times because cold water slows digestion and weakens immunity. A fully submersible water heater made for turtle tanks should always be used and placed safely to avoid burns. The basking platform must allow the turtle to sit completely out of the water and should have a dry surface at least the same size as the turtle’s shell, positioned directly under the heat and UVB light for proper warming and shell drying. The tank should never be placed near windows, doors, or cold air drafts, as even short exposure to cold air can cause stress, and cold air combined with warm water often leads to respiratory infections during winter.
5. Winter Habitat Setup for Land Turtles
Land turtles need dry and warm enclosures during winter. Damp substrate in cold weather increases the risk of shell rot and fungal infections. The enclosure should include a warm basking area and a sheltered resting place.
Humidity should remain balanced, not too dry and not too wet. Cold and damp conditions are very dangerous for land turtles.
6. Feeding Turtles During Winter
Turtles often eat less during winter. This is normal as their metabolism slows slightly. Active turtles should continue eating, but portions may be smaller. Overfeeding during winter can cause digestive problems.
Never force a turtle to eat. If a turtle refuses food but remains active and alert, it is usually normal.
When discussing winter feeding, Insects as a Natural Food Source for Aquatic Turtles helps owners understand safe, natural protein options for active turtles.
7. Feeding During Brumation Is Dangerous
If a turtle is brumating, feeding must stop completely. Food inside the stomach during brumation can rot and cause fatal infections. Brumation should only be done with healthy adult turtles and proper preparation.
Beginners should avoid brumation completely and keep turtles active with warmth and light.
Before offering any treats, owners should understand feeding risks, and Mealworms as treats for Turtles and Tortoises clearly explains proper usage and limitations.
8. Hydration Needs in Winter
Turtles still need water during winter. Aquatic turtles stay hydrated naturally, but water quality must remain clean. Dirty water causes infections faster during winter.
Land turtles should always have access to clean drinking water. Occasional soaking may be helpful if the environment becomes too dry.
Along with hydration, diet quality matters, and Insects as a Natural Food Source for Aquatic Turtles provides insight into balanced nutrition during colder months.
9. Common Winter Health Problems in Turtles
Winter weakens turtle immunity when care is poor. Many health problems appear during this season. Respiratory infections are very common in cold conditions. Shell infections also increase when turtles remain damp or cold.
Many winter mistakes are related to poor enclosure design, which is why How to Create the Best Tank for Your Aquatic Turtle is helpful for avoiding temperature and lighting errors.
Early treatment saves lives, so symptoms should never be ignored.

Early treatment saves lives, so symptoms should never be ignored.
11. Warning Signs of Winter Illness
Signs of illness include lack of appetite, swollen eyes, bubbles or mucus from the nose, wheezing sounds, soft shell, or extreme weakness. If these signs appear, warmth should be increased immediately.
Veterinary care from a reptile specialist is important if symptoms continue.
12. Outdoor Turtle Care During Winter
Outdoor turtles need extra protection during winter. In very cold regions, outdoor overwintering is risky for pet turtles. Freezing temperatures can kill turtles quickly.
Bringing turtles indoors for winter is often the safest option. Indoor care allows better control of heat and light.
Outdoor Pond Care in Winter
If turtles stay outdoors in ponds, the pond must be deep enough to prevent freezing. Shallow ponds are dangerous. Some ponds require heaters or de-icers to keep water from freezing completely.
Only strong, healthy turtles should remain outdoors. Weak or young turtles should always be moved indoors.
12. Common Winter Mistakes Turtle Owners Make
Many owners turn off heat lamps to save electricity. Others reduce lighting time or stop UVB use. Some assume turtles can handle cold naturally. These mistakes often lead to illness or death.
Captive turtles depend completely on their owners for survival.
13. Why Beginners Should Avoid Brumation?
Brumation requires strict temperature control, health checks, and experience. Mistakes can be fatal. Beginners should focus on active winter care instead.
Keeping turtles warm and awake is safer and easier for most pet owners.
14. Cleaning and Maintenance During Winter
Cleaning should not stop in winter. Aquatic tanks need regular partial water changes. Land enclosures must remain dry and clean to prevent mold and bacteria.
Cold weather does not stop bacterial growth. Clean habitats are essential year-round.
Winter care for turtles is about warmth, light, cleanliness, and observation. When turtles receive stable heat, proper UVB light, clean habitats, and correct feeding, they can stay healthy all winter.
Never take winter lightly. Good winter care protects your turtle’s life. By following this winter care guide for turtles, beginners can confidently provide safe and effective care during the cold season.
