Dogs and Indians

I don't know why but it's suddenly gotten very hot here. The whole summer was cool with foggy mornings, but things have heated up. I thought this is what you'd call an Indian Summer, but after looking it up, I believe the more accurate term would be that we are in the "dog days" of summer. The dog part apparently refers to the dog star Sirius (in Canis Major), and it hangs out in the sky in August and September, when it typically is the hottest.
An Indian summer occurs after the leaves have turned and the first killing frost has passed, but before the first snowfall, usually in October or November. Either way it's a' roasting out there!
