Phoenix-metro area--Arizona, here!
Temperature reached 113 degrees last Thursday, cooled down to around 108 degrees over the weekend, and we'll be back up to 111 degrees in the next day or so. Humidity has been low, so far--monsoon storms have not kicked in yet. But they probably will within the next 10 days or so. That means the dewpoint will be 55 degrees or higher most of the time--not sure what that translates to in terms of humidity, but, combined with the high temperature, it's extremely uncomfortable! *LOL*
So far, I've been turning the thermostats all the way up (around 90 degrees) when I get up in the morning. Actually one already is there, I just have to turn up the one on the side of the house where my bedroom is located. It stays there until I return home around 7 or 8 p.m., then I slowly turn it down to about 78 degrees before I go to bed so I'm very comfortable sleeping. The house has been staying at around 82 degrees, and I've been setting the thermostat at 85 degrees when I'm home on the weekend. I'll have to lower it a bit when the humidity becomes unbearable.
Electricity is expensive here, and with a 2400 sq.ft. all-electric house, the monthly electric bill can reach $400 very quickly!

Unfortunately, the electric company owned the gas company when my house was built, and they declared a moratorium on new gas lines about two years prior to the start of construction. Of course, when they sold the gas company about five years later, the new company completely bypassed this area. *sigh*
During the winter, I keep the house around 66 to 68 degrees, although I occasionally turn it up to 72 degrees on really cold mornings! Usually I just throw on sweats and exercise immediately! *LOL*
Over the years, I have learned that if I maintain a fairly constant temperature in the house, it's less expensive than if I constantly increase and/or decrease the temperature.
