Sullivan's on Castle Island hopes its reopening will signal spring — even as Boston prepares for snow

Sullivan's seasonal seafood restaurant on Castle Island will welcome back customers this Saturday. For many Bostonians, "Sully's" annual reopening marks the start of spring — regardless of whether the weather indicates otherwise.

"This weekend, unfortunately, it's going to be a little cold — 25 degrees, I think, is the high," said owner Brendan Sullivan. "So, a little disappointing there. But, you know, it's New England. If you don't like the weather, wait a minute, it changes. Maybe the following week, it'll be 60. Who knows?”

The previous weekend, it was indeed in the 60s. But on Thursday, as Sullivan and his employees prepared to open back up, a snowstorm was blanketing South Boston in a layer of snow and ice. And, forecasters are watching out for another major snowstorm headed toward the area Monday evening.

Despite the chill in the air, Sullivan, who purchased the business from his father in 2008, remains hopeful his restaurant's first day back will be a busy one.

"People come down with their grandparents, their kids," he said. "It's sort of a tradition that they're here for opening day. And I want to make sure it's a Saturday so they can enjoy that as well."

He said he's keeping about 3,000 pounds of french fries in the freezer — all of which he predicted would be gone after the first weekend.

He and his staffers will have to restock, as the concession stand will remain open through November.
