Sun and UV in Sydney
Australia experiences some of the strongest UV in the world, partly because of clear skies and the Earth's position relative to the sun during the southern summer. In Sydney, summer (December to February) midday UV frequently hits very high or extreme, and UV stays significant well into spring and autumn. The local 'Slip, Slop, Slap, Seek, Slide' message reflects just how strong the sun is.
When is UV highest in Sydney?
Because Sydney is in the Southern Hemisphere, its strongest UV falls over the southern summer: broadly December to February. As everywhere, UV peaks around solar noon, roughly 10am to 4pm. For more on this, see when is the sun strongest.
The UV index scale
| UV index | Risk level | What to do |
|---|---|---|
| 0-2 | Low | Minimal risk. Safe to be outside; sunglasses on bright days. |
| 3-5 | Moderate | Take care at midday. Use SPF 30+, a hat and shade around noon. |
| 6-7 | High | Protection needed. SPF 30+, cover up, seek shade 10am-4pm. |
| 8-10 | Very high | Extra protection. Avoid the sun at midday; SPF, clothing and shade are essential. |
| 11+ | Extreme | Take all precautions. Unprotected skin can burn quickly; stay inside or fully covered at peak hours. |
UV index categories follow the World Health Organization / US EPA scale.
