Hallmark Channel is kicking off its 13th annual Christmas in July event!

This year’s event will be headlined by the all-new, original docuseries Christmas at Sea, which premieres tonight (Monday, July 7) at 8 p.m. ET on Hallmark Channel, and streams next day on Hallmark+.

Here’s a plot summary: “Produced by Big Fish Entertainment for Hallmark, this four-part limited series captures the joy, connection, and community that define the Hallmark fan experience, as it follows passionate superfans aboard Hallmark’s inaugural Christmas Cruise from Miami to Nassau. Viewers will meet cruisers with unforgettable stories — a surprise proposal and wedding, lifelong best friends on a longawaited girls’ trip, a teenage grandson celebrating his 16th birthday with both grandmothers, and more — as they set sail for the ultimate fan adventure.”
