On the longest day of the year, HBO reminds us that winter is coming with a new teaser for Game of Thrones. Coming face to face with the Night’s King should cool you right off on this first day of summer.

Check out the trailer above, and then head over to Twitter where all kinds of wintry activities are underway, including a virtual scavenger hunt for the new season’s posters.

Game of Thrones returns to HBO July 16.
