Sun & UV travel guides
Heading somewhere sunny? These guides cover what UV levels to expect at popular destinations — often far higher than home — plus practical rules like how much sunscreen you can take in your carry-on. Every guide links to the live UV page for that destination, so you can check the real number the morning you land.
Start with the two most-requested destinations: Lanzarote and Tenerife, where Atlantic breezes hide a UV level that regularly hits 9–11 in summer — roughly double a northern-European beach day. Each guide covers the monthly UV pattern, burn times for fair skin and the local rules of thumb for shade hours.
Two practical notes before you fly: sunscreen counts as a liquid in hand luggage (100 ml max per bottle), and UV at your destination usually peaks between 11 AM and 3 PM local time — plan beach hours around it. For any city on your itinerary, the live checker shows the current value and hourly curve, and the scale guide explains what each number demands.
