For Pahrump weather averages,
www.city-data.com has some good info. Also, you can look up averages for specific date ranges through
Trip Planner : Weather Underground (the usual Pahrump zip code is 89048).
After moving here from Ohio, I'd say Pahrump does get colder than I thought it would in the winter - mainly at night in particular, but the summer so far is pretty much what I figured it would be. Dry heat I think is far better than humid heat, and (for me anyways) it means you can basically knock off about 10 degrees of dry heat to translate into what it feels to be in humid heat. Also, even in these latest few 105+ degree high days, I still don't physically sweat as much as I did when it was in the high eighties or low nineties in Ohio. Here, it feels a little more like when you open your oven door after preheating it to 400 degrees... it's hot, but it's not the end of the world. In Ohio, it just flat out felt like you wanted a cold shower immediately after spending as little as 5 minutes outside while standing still.
I hope that maybe helps to paint a halfway decent picture of what the weather is like here, along with the info from the links.
I too am much happier being a bit too hot than a bit too cold. :-)
