That's my understanding too. In fact, the hottest surface temperature recorded on Earth is much higher than the official temperature record because a surface gathers heat not only from air convection/conduction but direct radiation as well.
> Temperatures measured directly on the ground may exceed air temperatures by 30 to 50 °C (54 to 90 °F).[6] The highest natural ground surface temperature ever recorded may have been an alleged reading of 93.9 °C (201.0 °F) at Furnace Creek, California, United States, on 15 July 1972.[7] In 2011, a ground temperature of 84 °C (183.2 °F) was recorded in Port Sudan, Sudan.
