According to The Old Farmer’s Almanac today marks the beginning of the DOG DAYS most commonly experienced in the months of July and August, which typically observe the warmest summer temperatures. In the Southern hemisphere, they typically occur in January and February, in the midst of the austral summer. The Almanac lists the traditional period of the Dog Days as the forty days beginning July 3rd and ending August 11th, coinciding with the ancient heliacal (at sunrise) rising of the Dog Star, Sirius. These are the days of the year with the least rainfall in the Northern Hemisphere.
