As you can see by the photo the temperature is 96 deg. F. While I would not recommend a temperature above 90 Deg.F for any length of time, it is not fatal for a half a day at a stretch. Could be fatal if the turtle was excessively dessicated/dehydrated.
This picture just taken of 3 Gulf Coast babies maintained outdoors. One is completely hidden by the temp gun. Here, they stay burrowed under a very thick piece of styrofoam. I will be moving them to a cooler location.
