Do snakes hibernate in winter? It’s a common question for homeowners across Sydney as temperatures drop and snake sightings become less frequent. The short answer is no — snakes do not truly hibernate. Instead, they enter a natural state called brumation.
Understanding how snakes in winter behave can help you stay safe, protect your family and pets, and know when to call a professional snake catcher if needed.
What Is Brumation?
Brumation is a period of dormancy that reptiles go through during colder months. Because snakes are cold-blooded, they rely on environmental heat to regulate their body temperature.
As temperatures drop, their metabolism slows significantly. During snake brumation, snakes:
- Stop actively hunting
- Eat very little or not at all
- Remain hidden in sheltered locations
- Conserve energy until warmer conditions return
This is why winter snake activity is much lower than during peak snake season.
Hibernation vs Brumation
Many people ask, “do snakes hibernate in winter?” — but reptiles behave differently to mammals.
Hibernation
- Deep, uninterrupted sleep
- Body temperature drops significantly
- Little to no movement
Brumation
- Light dormancy
- Snakes may wake occasionally
- Can move if temperatures rise
- Still aware of surroundings
This is why snakes can still appear in winter under the right conditions.
Are Snakes Active in Winter?
Yes — but activity is reduced.
In Sydney, mild winters mean snakes may still come out on:
- Warm sunny days
- After rain followed by sunlight
- Short warmer weather periods
Some species, like eastern brown snakes, have been observed active even in cooler conditions. According to the Australian Museum, snakes may still bask during mild winter days.
So while snake activity in winter drops, it does not stop completely.
Why Snakes May Still Appear Around Homes
Even during colder months, snakes may still be found around homes. Properties often provide ideal conditions for shelter and food.
- Shelter: Under houses, sheds, retaining walls
- Food: Rodents remain active in winter
- Warmth: Concrete and structures retain heat
- Cover: Garden debris, timber piles, clutter
If you’re unsure what species you’ve seen, you can refer to our snake identification guide — always from a safe distance.
What to Do If You See a Snake
If you encounter a snake in winter, treat it seriously.
- Keep your distance
- Do not attempt to catch or kill it
- Keep children and pets away
- Monitor from a safe position if possible
Even during brumation, snakes will defend themselves if threatened.
For general safety advice, the RSPCA Australia recommends staying calm and allowing the snake to move away naturally.
If the snake is near your home or cannot be safely left alone, the safest option is professional snake removal.
Winter Snake Prevention Tips
Reducing your risk during winter is simple with a few preventative steps:
- Keep lawns short and maintained
- Remove debris and timber piles
- Control rodent activity
- Seal gaps around structures
- Avoid leaving clutter around your yard
For higher-risk properties, especially near bushland or waterways, our snake prevention services can help reduce long-term risk.
When Should You Call a Snake Catcher?
You should contact a licensed snake catcher if:
- The snake is inside your home or building
- You cannot safely monitor its location
- Pets or children are at risk
- The snake appears trapped or defensive
Our local licensed team safely relocates snakes in accordance with NSW regulations.
If you’re unsure what to do, it’s always safest to contact our team for guidance.

Conclusion
So, do snakes hibernate in winter? Not exactly. They enter brumation — a lighter, temperature-driven state that still allows occasional movement.
While snakes in winter are less active, they haven’t disappeared. Warm days, shelter, and food sources can still bring them close to homes.
