When Are the Dog Days Of Summer?

Quck answer

The dog days of summer are typically considered to be the hottest and most oppressive days of the season. They occur during the period from early July to mid-August, when the Dog Star, Sirius, rises and sets with the sun. These days are often characterized by sweltering heat, high humidity, and a general feeling of lethargy. The name “dog days” comes from the ancient belief that the combination of Sirius and the sun caused extreme heat and discomfort. However, the actual weather during this period can vary depending on location and climate.


Wow! It’s scorching in Wonderopolis today. Actually, it seems like the dog days of summer have arrived. But what does that mean exactly?

A lot of people believe the phrase “dog days of summer” comes from the fact that dogs tend to be a bit lazy during the hottest days of summer. And who can blame them? With all that fur, dogs can easily overheat if they exercise during the hot days of summer.

However, the phrase doesn’t come from lazy dogs lying around on hot and humid days. To find the answer, we just need to look up at the summer sky.

The ancient Romans referred to the hottest, most humid days of summer as “diēs caniculārēs” or “dog days.” This name came about because they associated the hottest days of summer with the star Sirius. Sirius was known as the “Dog Star” because it was the brightest star in the constellation Canis Major (Large Dog). Sirius is also the brightest star in the night sky.

The ancient Romans believed that Sirius radiated extra heat towards Earth because it was so bright. During the summer, when Sirius rises and sets with the Sun, they thought that Sirius added heat to the Sun’s heat, causing hotter summer temperatures.

For the ancient Romans, the dog days of summer occurred from around July 24 to August 24. However, over time, the constellations have shifted somewhat. Today, The Old Farmer’s Almanac lists the traditional timing of the dog days of summer as July 3 to August 11.

Although the dog days of summer are typically the hottest, they have nothing to do with dogs or the star Sirius. Instead, the tilt of the Earth explains why these days tend to be the hottest of the summer.

During summer in the Northern Hemisphere, the tilt of the Earth causes the Sun’s light to hit the Northern Hemisphere at a more direct angle and for a longer period of time throughout the day. This results in longer, hotter days during the summer.

This is why the dog days of summer are from late January to early March in the Southern Hemisphere. The actual dates of the dog days of summer will vary depending on location, latitude, and climate.
