Ok, cold for me
Temp was in high 30's at start & 40's most of cook with a wind of 15-20 mph.
Well you don't need a wind barrier or heating blanket!
Took a little longer to come to temp, & seemed to settle in at 250F instead of 275F but worked fine.
This is about as cold as I'll cook, heck any colder & I'll be in front of the fire not cooking outside
