UAE.. Low 40sC in the shade. Took a taxi to sort out a driving licence and, as the taxis were so cheap, kept the taxi on the clock. Got back and the taxi thermometer (ok, it was in the sun) read 56c! Sharjah may have been hotter but no way of proving it. Went to the desert zoo which is air conned. Walking back to the car, just across the other side of the car park, was evil.
89c in a sauna was pretty daft, in my younger days....if the thermometer was accurate.
