What I think saves us from too hot temperatures here is the wind who rarely stops. A few times lately there has been none, when that happens it's kind of scary, normally we at least see one little thing moving a little but seeing nothing move from the wind is very rare. Also the cold must come from the mountains that are around. When we do get hot days almost 100% when the dark comes it is cold or at least colder. With three Summers here we had to use our air conditioners less than ten times a year (the 1 upstairs is now broken...i bet this year we will get more hot days..hope not).
