To rephrase, if a rock sits outside in 10F weather with -10F windchill, is the rock’s surface temperature 10F or -10F?

The windchill effect is the same as sitting in front of a fan on a hot summer day. Say the room’s air temperature and everything in the room (including the rock) is at 85 deg F. Your body temperature is at 98 deg F. You have a “bubble” of stationary 98 deg F air surrounding your body, making you feel miserable. Now, you turn on a fan which blow 85 deg F air at you, which also blows away your 98 deg F bubble. You feel cooler with 85 deg F air hitting your skin, but the 85 deg F rock feels no temperature change with moving (vs. stationary) 85 deg F air around it.
