Minutes to sunburn by skin type

Estimated minutes until unprotected skin starts to burn at today’s peak UV index of 7.9 (12:00).

Skin typeTime to sunburn
Type I always burns, never tans≈ 17 min
Type II burns easily, tans a little≈ 21 min
Type III sometimes burns, tans slowly≈ 25 min
Type IV rarely burns, tans easily≈ 38 min
Type V very rarely burns, brown skin≈ 51 min
Type VI never burns, dark brown or black skin≈ 85 min

An estimate for unprotected skin from the minimal erythemal dose of each type (200, 250, 300, 450, 600 and 1000 J/m²) and UV index 1 = 0.025 W/m² of erythemal sun: minutes = dose / (UV × 0.025 × 60). Snow, sand and water reflect extra UV; altitude adds about 10 % per 1000 m. Not medical advice.

Questions

What is the UV index in Shiraz today?
On 16 October 2026 the forecast peak in Shiraz was 7.9 (Very high). The box at the top of the page loads today’s and tomorrow’s UV index from the NOAA GFS forecast every time you open it.
When is the sun strongest in Shiraz?
Around local solar noon, when the sun is highest: the UV index is usually above half its peak for about two hours either side. The page shows the exact hours above 3, 6 and 8 for today and tomorrow.
How long until I get sunburnt in Shiraz?
It depends on the UV index and your skin: at UV 8 very fair skin (type I) starts to burn in about 17 minutes, type III in about 25, type V in about 50. The table on this page works it out for today’s peak.
What SPF should I use?
The WHO says protection starts at UV 3: SPF 30 at moderate levels, 30+ at high, 50+ at very high and extreme, with shade, a shirt, a hat and sunglasses. Clouds lower the UV less than they lower the heat, so a cool cloudy day can still burn.

How this page works

The UV index is the one the UV layer of the map paints: NOAA GFS forecast (public domain), with the clear-sky UV from the sun angle and the GFS ozone and the cloud’s cut of the sunlight, every 3 hours on a 2° grid; between the steps the sun angle at Shiraz is computed every 15 minutes. A city-scale model: it does not see altitude, snow or local haze. Read in your browser on every visit.
