From Wikipedia:

The phrase Dog Days or "the dog days of summer", refers to the hottest, most sultry days of summer. They are a phenomenon of the northern hemisphere that usually falls between early July and early September but the actual dates vary greatly from region to region, depending on latitude and climate. Dog Days can also define a time period or event that is very hot or stagnant, or marked by dull lack of progress.
