A computer-controlled system of coolant-filled pipes under the sand will keep temperatures comfortable, reports The Sun.
The beach will be created next to the new Palazzo Versace hotel in the Arab state.
Guests wanting to chill out in summer heat hitting 50°C (122°F) will also have a cooled swimming pool and a gentle breeze generated by huge blowers.
Bosses hope the gimmicks at the hotel, due to open late next year or early 2010, will attract some of the 800,000 Brits who visit Dubai each year.
British firm Hyder Consulting is overseeing the construction. The five-star hotel is linked to the Versace fashion brand and aims to attract designer-conscious clients.
Soheil Abedian, president of the company that owns the Palazzo Versace, said: "This is the kind of luxury top people want."
But Rachel Noble, of Tourism Concern, said: "Dubai is like a bubble world where the things that are worrying the rest of the world, like climate change, are simply ignored so people can continue destructive lifestyles." (The Sun)
