UV index in Dubai in August
In August, the UV index in Dubai typically peaks around 8.7 at midday — very high on the WHO scale — with individual days reaching 9 in recent years. Sun protection is needed around the middle of the day.
How fast would you burn?
Estimated time to sunburn in unprotected midday sun at UV 8.7:
| Skin type | Time to burn |
|---|---|
| I — Very fair | ~15 min |
| II — Fair | ~19 min |
| III — Medium | ~27 min |
| IV — Olive | ~34 min |
Estimates from typical minimal erythemal doses — see methodology. Darker types (V–VI) burn slower still. Reflection off water or sand shortens all of these.
What to do about it
- Treat midday sun as hostile: SPF 50, a real hat, UV-blocking sunglasses, and shade between 11am and 3pm.
- Fair skin (types I–II) can burn in 15–25 minutes at these levels — reapply sunscreen strictly every 2 hours.
- UPF-rated clothing outperforms sunscreen for long days out — consider a sun shirt for beach or boat days.
