About 24c here in the South of the UK, just warm enough and not too warm if you get my drift

Oh and Shelagh (is that the Irish spelling of your name?) I think you are supposed to treat it like any burn, keep open to the air and don't put anything greasy on it, although have heard aloe vera is good.
Found this for you:
Lidocaine or Benzocaine can be administered to the spot of injury and will generally negate most of the pain. Lidocaine and benzocaine are a popular FDA approved local anesthetic pain reliever for sunburns and available at most drugstores in the United States in the form of ointment or spray.
The pain and burning associated with a sunburn can be relieved with a number of different remedies applied to the burn site. The skin can be hydrated by applying topical products containing Aloe vera and/or vitamin E, which reduce inflammation. Hydrocortisone cream may also help reduce inflammation and itching. Taking anti-inflammatory drugs such as ibuprofen or naproxen may help, DO NOT give aspirin to children.[32] Avoid the use of butter; This is a false remedy which can prevent healing and damage skin.[32] When treating open sores caused by a sunburn, like any other open skin wound, it is best to avoid lotions or other directly-applied ointments. However, antibacterial solutions and gauze can prevent skin infections.
There are two home remedies which have been known to help. One method involves applying a clean washcloth soaked with cool (not cold) milk, in the form of a cold compress. In addition to the cool temperature, a protein film will form to soothe the pain and the lactic acid will help reduce inflammation.[33] A solution of diluted white cider vinegar (approx. 1 cup in a tub of water) applied in a similar fashion may also ease pain
