Ever wondered where all the frogs vanish to when winter hits the UK? You’re definitely not the only one. Frogs don’t actually hibernate underwater like turtles do, despite what some people say.
Instead, they hide away in spots like under logs, piles of leaves, or sometimes just beneath the soil’s surface. These places let them stay safe and slow everything down for the winter.
Sometimes, if the weather gets a bit milder, you might catch a glimpse of a frog hopping around in winter. They’ll come out for a quick snack.
If you know where your garden frogs go in the cold months, you can help them out and make your garden a little haven for them all year.
How Frogs Survive Winter in the UK
UK frogs have to deal with freezing temperatures that make it tough to stay active. When it gets cold, they slow down and search for safe places to wait it out.
Their bodies and habits shift, helping them dodge predators and survive the chill. They don’t just tough it out—they adapt.
Brumation Versus Hibernation
Do frogs hibernate like bears? Not really. Frogs go into a state called brumation. It’s kind of like hibernation, but it doesn’t last as long or go as deep.
Since frogs are cold-blooded, their body temperature drops with the environment. During brumation, they barely move.
Their heart and breathing slow right down. They stop eating, but if things warm up, they might shuffle around a bit. This low-energy mode lets frogs save oxygen and last longer without food.
Adaptations for Cold Weather
Frogs have some clever tricks for surviving winter. They slow their metabolism, which saves energy.
Some UK frogs even make a natural antifreeze in their bodies. That stops ice from forming in their cells—otherwise, they’d be in real trouble.
Their skin helps them breathe, even when they’re buried or underwater. Staying moist is key, because dry spots can be dangerous.
That’s why frogs always choose damp places to hide when it’s cold.
| Adaptation | Purpose |
|---|---|
| Slowed metabolism | Saves energy and oxygen |
| Natural antifreeze | Prevents ice damage to cells |
| Moist skin | Allows breathing and hydration |
Where Frogs Hide and Shelter
Frogs don’t just pick any spot for winter. Most leave ponds and dig into the ground.
You’ll sometimes find them tucked under leaves, inside compost heaps, or hiding in logs. These shelters keep them warmer and damp.
Some, especially the males, stick around in ponds. They bury themselves in mud or under leaves.
If the pond doesn’t freeze solid, water can be a safe bet. But it’s risky—smaller ponds might freeze over or run out of oxygen, and that’s bad news for any frog caught there.
If you want to give frogs a hand, leave some log piles or compost heaps in your garden. It really helps them get through winter.
Risks and Dangers During Winter
Winter isn’t easy for frogs. Sometimes ponds freeze all the way or lose oxygen, which puts frogs in danger if they’re hiding there.
Dry shelters can be just as risky, since frogs need moisture and can dry out fast.
Predators like foxes or birds might grab frogs when they venture out on warmer days. You might even spot a dead frog near a pond—sad, but it happens.
Climate change only piles on more problems. Warmer winters sometimes wake frogs up too early, and they use up their energy stores.
Floods or heavy rain can wash away their shelters, which is another headache for them.

Frog Winter Habitats and Life Cycle
UK frogs find all sorts of places to ride out the cold and get ready for spring. Where they go depends on the species and their usual hangouts.
You’ll spot them in ponds, gardens, and burrows underground. Their life cycle slows down in winter, but they’re gearing up for spring as soon as it warms.
Ponds and Aquatic Overwintering
Some frogs, especially the aquatic types, spend winter in ponds. They bury themselves in mud and leaves at the bottom.
Ponds with a steady water flow don’t freeze as easily, so they’re safer.
These frogs make it through low oxygen by slowing their metabolism. It sounds risky, but it means they’re right there when breeding season starts.
You might see common frogs and newts using bigger garden ponds or natural ponds. The water keeps them from freezing, but they stay almost motionless until it’s warmer.
Garden and Terrestrial Refuge
Not all frogs hang out in water for winter. Many common frogs, toads, and some newts look for shelter on land.
They’ll hunker down under leaves, inside compost heaps, or even in holes left by mammals. These spots are damp and protect them from harsh cold.
Frogs have really thin skin, so they can dry out quickly. That’s why they always look for moist hideouts.
If you have a garden pond or just a pile of leaves, you might be giving local frogs a safe spot. Leaving parts of your garden undisturbed during winter can really help them.
Interaction With Other Amphibians
In winter, different amphibians often end up sharing hiding spots. Frogs, toads, and newts can all overwinter in the same pond or burrow.
They might compete for space, but sharing helps make the shelter more stable. Newts usually stay deeper in the pond, while frogs prefer the muddy edges.
Even when it’s cold, some amphibians move a little on warmer days. They shift around to find better shelter or more moisture.
Preparation for Spring Breeding
As soon as temperatures start to climb in late winter or early spring, frogs shake off hibernation and head out. You’ll probably spot them migrating back to ponds, ready for breeding season.
The males tend to show up first, trying to claim the best spots for themselves. Not long after, the females arrive and lay frogspawn in the water.
Eggs hatch into tadpoles and froglets, and these little ones will spend some time growing in the pond before they ever hop onto land. This whole cycle only works if frogs make it through winter safely in their habitats.
