When temperatures drop and the days become shorter, sun protection is often one of the first things to disappear from our daily skincare routines. With colder weather, darker mornings and less sunshine, it is easy to assume that the risk of sun damage is significantly lower during the winter months.
However, protecting your skin from the sun is not just a summer concern. Even when temperatures are low, ultraviolet (UV) radiation can still reach your skin and contribute to premature ageing, pigmentation and an increased risk of skin cancer.
In fact, winter sun in Europe can still expose your skin to potentially harmful UV radiation, particularly when spending time outdoors, travelling to higher altitudes or enjoying winter sports.
So, can you really get sun damage in winter? The answer is yes. Understanding how UV radiation behaves throughout the year, and why consistent sun protection matters, can help you protect your skin during every season.
Can You Get Sun Damage in Winter?
Yes, it is possible to experience sun damage during winter, although the level of risk depends on where you are, the time of day and the environmental conditions.
The sun produces ultraviolet radiation throughout the year. While UV levels are generally lower during winter in northern parts of Europe, they can remain significant in other regions, particularly destinations closer to the equator and areas at higher altitudes.
This is particularly important for anyone travelling abroad during the winter months. A winter holiday in southern Europe, for example, may involve considerably more sun exposure than a typical winter day in the UK. Similarly, a skiing holiday in the Alps can expose your skin to substantial UV radiation, even when temperatures are below freezing.
The important distinction is that cold weather does not necessarily mean low UV exposure. Temperature measures how warm or cold the air feels, whereas UV radiation is a separate part of sunlight that can affect your skin without you necessarily noticing it.
According to the World Health Organization (WHO), UV exposure is influenced by several environmental factors, including latitude, altitude, cloud cover and reflection from surrounding surfaces. These factors help explain why winter sun in Europe can still present a risk to your skin.
Understanding UVA and UVB Radiation
To understand why winter sun in Europe can affect your skin, it is useful to know the difference between the two main types of ultraviolet radiation that reach the Earth’s surface: UVA and UVB.
Although both can contribute to skin damage, they affect the skin in different ways.
UVA Rays: Premature Skin Ageing
UVA rays have a longer wavelength and penetrate deeper into the skin than UVB rays. They are associated with premature skin ageing, including:
- Fine lines and wrinkles.
- Loss of skin elasticity.
- Uneven skin tone and pigmentation.
- Changes in skin texture.
- Long-term damage to skin cells.
UVA radiation is present throughout the year and is less affected by seasonal changes than UVB. It can also penetrate glass, meaning that prolonged exposure through windows may contribute to cumulative skin damage.
This is one reason why winter sun in Europe should not be overlooked, particularly when spending extended periods outdoors or travelling to destinations with higher UV levels.
UVB Rays: Sunburn and Skin Damage
UVB rays have a shorter wavelength and primarily affect the outer layers of the skin. They are responsible for most sunburn and play a significant role in the development of skin cancer.
UVB intensity varies more noticeably throughout the year. In northern Europe, levels are generally lower during winter because the sun sits lower in the sky and its rays travel through more of the atmosphere before reaching the ground.
However, UVB exposure can increase considerably when travelling further south or visiting high-altitude destinations.
Both UVA and UVB radiation can damage the DNA within skin cells. Although the body has mechanisms to repair some of this damage, repeated exposure can allow damage to accumulate over time.
Why Is Winter Sun in Europe Still a Risk?
There are several reasons why your skin may be exposed to harmful UV radiation during winter, even when the weather feels cold.
1. Travelling to Southern Europe
Many people associate winter holidays with escaping colder weather. Destinations such as Spain, Portugal, Cyprus and the Canary Islands can offer milder temperatures and more sunshine than the UK during winter.
However, travelling south generally means moving closer to the equator, where UV levels can be higher.
This means that winter sun in Europe can provide enough UV exposure to cause sun damage, particularly when spending several hours outdoors.
It is worth remembering that your skin may be less accustomed to direct sunlight during winter, especially if you have spent several months indoors or wearing clothing that covers most of your body.
If you are travelling somewhere sunnier, it is sensible to check the local UV index rather than relying on the temperature or weather forecast to determine whether sun protection is needed.
2. Higher Altitudes and Skiing Holidays
One of the biggest misconceptions about winter sun is that snow and cold temperatures offer natural protection from UV radiation.
In reality, skiing and snowboarding holidays can expose your skin to particularly high levels of UV radiation.
There are two main reasons for this:
- Higher altitude: The atmosphere becomes thinner at higher elevations, meaning less UV radiation is absorbed before reaching your skin.
- Snow reflection: Fresh snow reflects a significant proportion of the sun’s UV rays, increasing the amount of radiation reaching exposed areas of your body.
According to the Met Office, snow can reflect around 85% of UV radiation. This can increase exposure to areas such as your face, ears and the underside of your chin.
Even if you are wearing several layers of clothing, your face, neck and hands may remain exposed for extended periods.
3. UV Radiation Can Pass Through Clouds
Another common misconception is that cloudy weather eliminates the risk of sun damage.
Although cloud cover can reduce UV exposure, it does not block all ultraviolet radiation. Some UV rays can still reach your skin on overcast days.
This is particularly important when travelling, as people may be less likely to apply sunscreen when the sun is not immediately visible.
The WHO explains that UV levels can remain relatively high under certain cloudy conditions. Therefore, checking the UV index is a more reliable way to assess exposure than simply looking outside.
4. Cumulative Sun Exposure Throughout the Year
Sun damage is not always immediately visible. While sunburn is an obvious sign of excessive UV exposure, other forms of damage can develop gradually.
Repeated exposure to UVA and UVB radiation can contribute to changes in the skin over time, including pigmentation, wrinkles, loss of elasticity and an increased risk of skin cancer.
This means that occasional periods of unprotected exposure can contribute to your overall UV exposure, even if you do not experience sunburn.
Winter sun in Europe is therefore worth considering as part of your wider approach to skin health, rather than treating sun protection as something that only matters during summer holidays.
What Does Sun Damage Look Like?
Sun damage can present in several different ways, depending on the type of exposure, your skin type and how frequently your skin has been exposed to UV radiation.
Some changes develop gradually, while others may become noticeable following a period of intense sun exposure.
Common signs of sun damage include:
- Pigmentation: Dark patches, freckles and uneven skin tone caused or worsened by UV exposure.
- Fine lines and wrinkles: UVA exposure can contribute to the breakdown of collagen and elastin, which help maintain the skin’s firmness and structure.
- Loss of elasticity: Long-term UV exposure can make skin appear thinner, less firm and more weathered.
- Rough skin texture: Repeated exposure can contribute to roughness and changes in the skin’s surface.
- Actinic keratoses: Rough, scaly patches that develop on sun-exposed skin and are associated with cumulative UV damage. These are considered precancerous changes because some can develop into squamous cell carcinoma.
It is important to recognise that not all pigmentation, skin lesions or changes in skin texture are caused by sun exposure. New or changing lesions should be assessed by our team, through our walk-in mole screening service.
Sun damage can affect people of all skin tones. Although people with fairer skin generally have a higher risk of burning, darker skin is not immune to UV-related damage or skin cancer.
How to Protect Your Skin During Winter
Understanding the risks of winter sun in Europe is the first step towards protecting your skin. Fortunately, there are several straightforward ways to reduce unnecessary UV exposure without having to avoid spending time outdoors.
1. Wear Broad-Spectrum Sunscreen
Sunscreen is an important part of protecting exposed skin when UV levels are high enough to warrant protection.
Look for a broad-spectrum sunscreen that offers:
- SPF 30 or above: Helps protect against UVB radiation, which is primarily responsible for sunburn.
- At least 4-star UVA protection: Helps protect against UVA radiation, which contributes to premature skin ageing and other forms of skin damage.
Apply sunscreen generously to exposed areas, including your face, neck, ears and hands. Reapply regularly, particularly after sweating, swimming or wiping your skin.
If you are travelling to a sunny destination or spending time on the ski slopes, make sure sunscreen is part of your daily routine.
2. Check the UV Index
Rather than judging the strength of the sun by temperature or cloud cover, check the UV index before spending extended periods outdoors.
The UV index measures the strength of ultraviolet radiation and indicates the potential risk of damage to your skin and eyes.
The WHO recommends taking sun protection measures when the UV index reaches 3 or above.
3. Wear Protective Clothing and Sunglasses
Sunscreen should not be your only form of protection.
When spending time outdoors, particularly at higher altitudes, consider:
- Wearing sunglasses that offer 100% UVA and UVB protection.
- Using a hat to protect your face, ears and scalp.
- Wearing clothing that covers exposed areas of skin.
- Choosing ski goggles with appropriate UV protection when participating in winter sports.
These measures are particularly important when snow is present, as reflected UV radiation can increase exposure to areas that might otherwise be less exposed to direct sunlight.
4. Be Particularly Careful During Winter Holidays
If you are travelling somewhere warmer, skiing or spending extended periods outdoors, take extra precautions.
Avoid spending prolonged periods in direct sunlight when the UV index is high, seek shade where possible and remember that sunscreen should be used alongside protective clothing.
Winter sun in Europe may feel less intense than the summer sun, but this does not mean that your skin is automatically protected.
Do You Need to Wear SPF Every Day During Winter?
This is a common skincare question, and the answer depends on your location, skin type and daily activities.
In the UK, UV levels are generally low during the winter months, particularly in December and January. According to Cancer Research UK, the sun is typically strong enough to cause skin damage between mid-March and mid-October.
However, this does not mean that everyone should follow exactly the same skincare routine throughout the year.
If you are travelling abroad, spending time at higher altitudes or visiting somewhere with stronger UV levels, your approach to sun protection should reflect the conditions.
For people who spend considerable time outdoors, checking the UV index is a useful way to make informed decisions.
It is also worth remembering that some people may have additional reasons to take care with sun exposure, including certain skin conditions, medications that increase photosensitivity or a history of skin cancer.
Ultimately, winter sun in Europe is not something to be dismissed simply because it is colder outside. Understanding your individual exposure and taking appropriate precautions is more important than following a rigid seasonal skincare routine.
When Should You See Our Dermatologists About Sun Damage?
Although many signs of sun damage develop gradually, it is important to pay attention to changes in your skin.
UV exposure is a recognised risk factor for skin cancer, making it important to monitor existing moles and be aware of any new or unusual skin lesions.
You should seek professional assessment if you notice:
- A mole that changes in size, shape or colour.
- A new mole or unusual skin growth.
- A lesion that becomes itchy, painful, crusty or bleeds.
- A sore that does not heal.
- A persistent rough or scaly patch of skin.
The ABCDE method can also help you recognise some potential warning signs of melanoma:
| Letter | What to look for |
|---|---|
| A – Asymmetry | One half of the mole looks different from the other. |
| B – Border | The edges are irregular, blurred or uneven. |
| C – Colour | There are different shades or uneven colouring. |
| D – Diameter | The mole is larger than 6mm, although melanomas can be smaller. |
| E – Evolving | The mole changes in appearance, size or sensation. |
Not every changing mole is cancerous, and some skin cancers do not follow these typical characteristics. If you are concerned about a change, seek medical advice rather than waiting for further symptoms to develop.
At Cathedral Dermatology, our dermatology team provides specialist assessment of a wide range of skin concerns. Our mole screening service also offers access to imaging, with reviews undertaken by our dermatology doctor team within 72 hours.
Early assessment is important when identifying potentially concerning changes and determining whether further investigation or treatment is required.
Protecting Your Skin Is a Year-Round Commitment
It is easy to associate sun protection with summer holidays, warm temperatures and spending time at the beach. However, UV exposure does not disappear when the seasons change.
Whether you are enjoying a winter getaway in southern Europe, skiing in the Alps or simply spending time outdoors at home, understanding how UV radiation affects your skin is an important part of maintaining long-term skin health.
While the level of risk varies depending on your location and the time of year, winter sun in Europe can still contribute to skin damage, particularly at higher altitudes and in destinations with stronger UV levels.
By checking the UV index, wearing appropriate sunscreen when needed and paying attention to changes in your skin, you can take practical steps towards protecting your skin throughout the year.
