Summer fans, rejoice: The season officially begins Friday. The summer solstice, which falls on June 21, marks the astronomical start of summer for the Northern Hemisphere. At 11:54 a.m. ET | 8:54 a.m.
Scorching temperatures around the world last month tied August 2019 as the second-hottest August on record and capped off the hottest Northern Hemisphere summer (June through August), tied with 2016.
On vacation, you're free to follow your heart.
