I had a travel assignment in Joshua Tree for 15 months. One day in June, me and my sis drove through the park down to Palm Springs and watched the temp climb up to 127! It was so hot, on a Saturday, we got up front parking at Ruben and Ozzy's Oyster bar. I miss that place... but not for the high temps!Mine will sometimes go 81-82, but it's usually around 78-79. I've never seen it impact anything. I'm out in the desert, so we have to run AC during the summer or I'd come home to a 110 degree home.
