When should children wear a winter jacket? A guide to temperatures and changeable weather

Short answer: There is no fixed temperature at which all children should switch to a winter jacket. Consider the temperature, wind, rain, activity level and how long the child is outside. In mild autumn weather, a transitional jacket is often enough, while colder and windier days may require a warmer winter jacket and suitable layers underneath.

As summer draws to a close and the mornings become cooler, many parents ask the same question: When should children actually start wearing a winter jacket?

Should the winter jacket already come out at 10 degrees? Is a transitional jacket enough at 5–10 degrees? And how can you tell whether the child is cold or has actually put on too many clothes?

There is no single temperature that suits all children. Wind, rain, activity level and how long the child stays outside also play a major role.

Here is a practical guide to choosing between a transitional jacket, lightweight down jacket and winter jacket as the temperature starts to drop.

When is it time for a winter jacket?

As a simple rule of thumb, you can use the following:

Above 15°C: A lightweight jacket or sweater is often sufficient.
10–15°C: A transitional jacket and possibly an extra layer are often a good choice.
5–10°C: A warm transitional jacket or lightweight down jacket may be suitable.
Around 5°C and below: A warmer winter jacket typically becomes more appropriate.

The temperatures are a guideline. Wind, rain and moisture can make 8°C feel significantly colder, while an active child on a sunny day may feel warm even at relatively low temperatures.

What should children wear at 10–15°C?

At 10–15°C, a heavy winter jacket will often be too warm, especially for children who run, cycle or play outside a lot.

Here, layering often works better:

Long-sleeved top → lightweight knitwear or fleece → transitional jacket

If the temperature rises during the day, it is easy to remove a layer.

If you are unsure why a transitional jacket is practical at this time of year, you can read our guide The importance of transitional jackets for children: A guide for parents.

What should children wear at 5–10°C?

When the temperature drops to around 5–10°C, the choice becomes more individual.

On a dry, windless day, a warm transitional jacket may still be sufficient for an active child. If it is cold, windy, or humid, a lightweight down jacket may be a better choice.

A lightweight down jacket can be practical during the transitional period because it provides extra insulation without necessarily feeling as heavy as a thick winter jacket.

At Lilla Villa, you can see our selection of down jackets and transitional jackets for children.

When should the warm winter jacket come out?

When the temperature approaches around 5°C or below, a warmer winter jacket will typically become more relevant.

But temperature alone should not determine your choice. Also consider:

How long will the child be outside?
Will the child be running and playing or sitting more still?
Is it windy?
Is the weather dry or humid?
Is the child already wearing several warm layers?

A child who cycles to school and plays actively during breaks generates more body heat than a child who spends more time standing or sitting still outdoors.

Transitional jacket, lightweight down jacket, or winter jacket?

The Danish autumn makes it practical to have more than one option in the wardrobe.

The transitional jacket is suitable for milder autumn days and makes it possible to add or remove layers.

The lightweight down jacket can be a good middle ground when the transitional jacket starts to feel too cool, but the heavy winter jacket is still too warm.

The winter jacket really comes into its own on cold days, when the child needs more insulation and protection.

Therefore, you do not need to choose a specific date to put away the transitional jacket. In September, October, and sometimes further into autumn, both jackets can easily be used depending on the day's weather.

Is a down jacket a good choice for children?

One of the advantages of down is that it can provide good insulation relative to its weight. This is practical for children, who still need to be able to move freely when playing and being active outdoors.

When choosing a winter jacket, however, you should not only consider the filling. Fit, freedom of movement, length, hood, fastening and how the jacket will be used in everyday life are also important.

Examples of different types of down jackets

Needs change throughout autumn and winter, so different types of jackets may suit different periods.

For colder days, a shorter puffer model can be practical if the child needs freedom of movement at school and during play.

If the child needs more coverage around the hips and thighs, a longer winter jacket may be suitable. See the current down jackets and winter jackets for children and compare the specific model's length, filling and fit.

Always check the individual jacket's product description, size and features when choosing a model.

How can you tell if the child is too warm?

A very warm jacket is not automatically the best choice.

If the child is sweating or becomes very hot and damp around the neck or upper back, it may be a sign that the child is wearing too many clothes.

Therefore, feel the back of the neck or upper back after outdoor activity. The child may feel warm, but should not be very hot or damp.

Hands can feel cold even when the rest of the body is at a comfortable temperature, so do not judge based on the hands alone.

Layering is particularly practical in autumn

September and October can bring cold mornings and significantly milder afternoons.

Layering makes it easier to adjust clothing throughout the day.

On a mild autumn day, for example:

Long-sleeved top → thin fleece or knitwear → transitional jacket

When the weather gets colder:

Long-sleeved top → possibly a mid-layer → down jacket or winter jacket

This makes it easier for the child to maintain the right temperature without being unnecessarily bundled up.

How to care for your child's down jacket

Once the winter jacket is in use, proper care is important to preserve it.

Down jackets require a little more care when washing and especially drying, so the down filling does not end up clumping together.

Read our guide Keep your child's down jacket clean and fresh: Expert tips for washing and drying if the jacket needs washing.

In short: When should children start wearing a winter jacket?

There is no one specific date or temperature that suits all children.

At 10–15°C, a transitional jacket will often be a good starting point.

At 5–10°C, a warm transitional jacket or lighter down jacket may be suitable, depending on the wind, weather, and the child's activity level.

When the temperature drops to around 5°C or below, a warmer winter jacket typically becomes more relevant.

The most important thing is to combine the weather forecast with the child's activity level and regularly check whether the child is comfortable.

This makes it easier to get through the changeable Danish autumn and winter weather without the child getting too cold or too warm.

Safety and temperature

When it comes to baby sleep, it is important to start with the baby's actual temperature and the specific sleeping bag's instructions. Feel the baby's chest, back, or neck and remove a layer if the skin feels warm or damp. Hands and feet may feel cooler without the baby necessarily being cold.

If you are unsure about temperature, sleep, or clothing, professional health advice should take precedence over general product guides. See, among other resources, Sundhed.dk's advice for newborns.
