Sunburn effect (as measured by the UV index) is the product of the sunlight power spectrum (radiation intensity) and the erythemal action spectrum (skin sensitivity) across the range of UV wavelengths. [9] [10] The UV index is a number linearly related to the intensity of sunburn-producing UV radiation at a given point on the Earth's surface.
Highest ultraviolet index measured: On 29 December 2003, a UV index of 43.3 was detected at Chile/Bolivia's Licancabur volcano, at 19,423 feet (5,920 m) altitude. A light-skinned individual in such conditions may experience moderate sunburn in as little as 4 minutes.
Fuerteventura (Spanish: [ˌfweɾteβenˈtuɾa] ⓘ) is one of the Canary Islands, in the Atlantic Ocean, geographically part of Macaronesia, and politically part of Spain. It is located 97 km (60 mi) away from the coast of North Africa .

Sunburn effect (as measured by the UV Index) is the product of the sunlight spectrum at the Earth's surface (radiation intensity) and the erythemal action spectrum (skin sensitivity). Long-wavelength UV is more prevalent, but each milliwatt at 295 nm produces almost 100 times more sunburn than at 315 nm.

And they don't always have the number of minutes decreasing linearly with rising UV index. As this article mentions in the intro, the UV Index has been adopted by the World Health Organization and World Meteorological Organization. But I haven't been able to find any information through either organization on how UV index corresponds to sunburn ...
There may be contributing factors of the wind to windburn, and similarly, sunburns. Most importantly, the cooling effects of the wind decrease the perception of heat and burning, meaning individuals are less likely to seek shade or to protect themselves against the sun, and are more likely to stay exposed to the burning effects of the sun's UV radiation for longer.
