June 21 – September 22, 2025
The year 2030 has 365 days.
On average, summer lasts for 93.6 days in the Northern Hemisphere and 89.0 days in the Southern Hemisphere. Average season lengths: March equinox to June solstice: 92.8 days.
The shift is being felt across the globe thanks to climate change. A study on the Northern Hemisphere’s climate found summer’s length went from 78 to 95 days on average from 1952 to 2011.
Because the Sun travels across the sky in its most elongated path during the summer solstice, that day has the most daylight hours.
And let’s remember why we have a long summer vacation. The tradition goes back to the agricultural economy. Kids were released from school so they could work on the farm. Gone are the days when families needed child labor in the field.
The heat is contributing to tiredness and lethargy. The excessive sweat that occurs during summer drains out all the energy that we store. Thus, it is very common to feel a bit lazy during the summer. Due to heat, we even lose our appetite and the heat takes a toll on our body.
The year 2024 is a leap year, with 366 days in total.
During our summer, the Northern Hemisphere leans toward the sun in its revolution, there are more daylight hours, and the sun’s angle is more perpendicular to us than at other times of year. The longer days and more concentrated sunlight and results in more heating.
