Nothing says August heat like Pumpkin Spice Latte.

The unofficial drink of autumn will return to Starbucks nearly a full month before the last day of summer.

Workers told Business Insider the PSL will return Tuesday, Aug. 27, the earliest it has ever officially appeared on the Starbucks menu.

Starbucks has not officially said when the latte will return, and a representative told Business Insider “the company had nothing to share on the topic at this time.”

August 27 might be the earliest official launch, but it’s only a day earlier than 2018’s return.

Before last year, Business Insider noted, the PSL officially launched on the Tuesday after Labor Day every year. In 2018, that changed to the Tuesday before Labor Day, which would also be this year’s launch.

Dunkin’ Donuts is hoping to jump on the pumpkin spice train earlier than Starbucks.

The doughnut chain's full pumpkin menu — including the new Cinnamon Sugar Pumpkin Signature Latte — debuts August 21. Dunkin' will bring back its classic pumpkin-flavored coffees and muffins, and introduce a pumpkin espresso.
