Sun protection when the sky is cloudy
A cool or cloudy day can feel comfortable while still allowing ultraviolet exposure.

A little context: this note is for adults with mild symptoms. Pregnancy, long-term conditions, or reduced immunity can change what is safe. Ask a professional if you’re unsure.
Let’s start here
A cool or cloudy day can feel comfortable while still allowing ultraviolet exposure. Plan protection around the time outdoors rather than whether the sunshine feels hot.
A few small things to try
- Plan coverage for the whole outing
- Use sunscreen on uncovered skin
- Take shade breaks before discomfort begins
Plan practical skin protection
Choose suitable covering clothing and shade, and use an appropriate sunscreen on exposed skin. A walk, gardening session or outdoor lunch can last longer than intended, so keep protection within reach. Temperature and a pleasant breeze are not reliable signals that your skin is protected.
Follow-through and limits
For travel, check local conditions and plan breaks under proper cover. Water, sand and snow can add reflected exposure, making clothing and eye protection useful even when the air is cool. Do not wait for skin to feel hot before deciding that an outdoor day has lasted long enough.
Mild sunburn means tender skin without blisters or illness. Move out of sunlight, cool gently and protect the area until it heals. Skin colour alone does not show severity on every skin tone; tenderness, warmth and swelling matter too. A tan does not make future exposure safe.
A couple of things to skip
- Do not use ice directly, pop blisters or pull peeling skin away.
- Do not continue sunbathing or use a tanning bed while skin recovers.
When to ask for help
Get prompt medical advice for blistering or swelling, fever, headache, dizziness, sickness or cramps after sun exposure. Confusion, collapse or suspected heatstroke is an emergency. A new or changing skin lesion needs a clinician even if it is not painful.
If symptoms are severe or rapidly worsening, use your local emergency service. A little more on getting help.
