That happened fast.

Summer solstice, first official day of summer, happened less than two weeks ago.

You need to check out the haunted village at Michael's. Incredible stuff this year

Depends on the science you’re wanting to use. Haha.

Astronomically it’s approximately September 22nd. Meteorologically it’s September 1st.

Regardless, it’s not next month

According to the Sun, Fall does start in August. Midsummer in the solar calendar is the Summer Solstice. Summer is the approximately 90 day period with the solstice as the midpoint. Mid-autumn is the autumnal equinox, therefore solar autumn begins approximately 45 days before the equinox. Midsummer and midwinter have been around for millenia.

If you want to understand this visually, graph the first derivative of day length. Mathematically , summer is the ~90 day period when the first derivative of day length declines at the steepest rate aka when the second derivative has relatively large negative values
