How long can you stay in the sun at UV 8?

UV 8 · Very high

UV 8 opens the 'very high' band. At this strength, very fair skin can start to burn in about 17 minutes, fair skin in around 21, and even skin that 'never burns' at home in Europe is on a countdown. UV 8 is a routine late-morning reading in an Australian summer, not an unusual event.

Burn times at UV 8, by skin type

Estimated from typical minimal erythemal doses. Reflection off sand, water or snow shortens all times. SPF 50 times assume proper application and are capped at 4 hours, reapply every 2. Educational only.

When and where UV 8 happens in Australia

Every Australian capital spends serious time at UV 8. It's a standard midday peak for Melbourne and Adelaide through November and February, for Sydney from October, and a mid-morning stepping stone on any January day that peaks extreme. Brisbane and Perth reach UV 8 middays from September through April. This is also the level European and North American visitors most misjudge, UV 8 is close to the highest reading a UK summer ever produces, and here it's Tuesday.

What protection looks like at this level

At UV 8, protection stops being about sunscreen alone. Cover up: densely woven clothing blocks UV far more reliably than a film of sunscreen that's rubbing off. Plan around the middle of the day, reapply sunscreen every two hours without fail, and get fair-skinned kids into rashies and shade. Sand and water reflection add to the number on the forecast.
