I live in Australia and Summer temperatures vary between 30 degrees Celsius and about 44 degrees Celsius. I do not use any air conditioners as they easily dry me out by pumping very dry air around. What suits me, but may not suit you, is to get a wet towel and put it around my neck and partly down my upper chest. Sit in a lazy chair in the shade and DO NOTHING! Keep the towel at least moist and don't fall for the temptation to swim in the pool in the sun. Just relax.
Enjoy your MG as best you can.
All the best, Jeff.
