Turkey Day has officially begun.

The 93rd annual Macy’s Thanksgiving Day Parade kicked off Thursday morning to cheers of eager spectators who packed Manhattan sidewalks.

Skies were partly sunny with temperatures lingering in the high 40s as the parade got underway and the holiday season officially commenced at 9 a.m.

More than 3.5 million spectators were expected along the 2.5-mile parade route between the Upper West Side and Herald Square to feast their eyes on the famed flight of 16 giant helium balloons, including Dr. Seuss’ “The Grinch,” Greg Heffley from “Diary of a Wimpy Kid,” Olaf from the Disney flick “Frozen,” and the “Trolls” balloon.

Illinois mom Cassie Lee, 37, and her daughters McKinley, 1, and Kennedy, 8, were among the first-timers at the parade.

“I watched it my whole life on TV. This is definitely checking an item off my bucket list to watch it here,” Lee said, adding that her daughter Kennedy was especially excited to get a glimpse of the Astronaut Snoopy balloon.

It was touch-and-go with the larger-than-life character balloons this week due to fears that wind gusts could ground the iconic flight of balloons, but in the end, the wind proved no match for the colorful inflatables.

Sustained winds of 23 mph and gusts above 34 mph would have forced authorities bring down the balloons.

“We were a little worried [about the possibility that the balloons wouldn’t fly],” said New Yorker Kristie Forbes-Wronko, 50, who was at the parade with her daughter Andyn Gay, 13. “We wake up every year to watch the Thanksgiving parade [on TV]. We’re just so happy to be here.”

The 93rd edition of the parade features the massive character balloons, 40 novelty balloons, heritage balloons, other forms of balloon displays, 26 floats, 1,200 cheerleaders and dancers, including the Radio City Rockettes, more than 1,000 clowns and 11 marching bands.

The new giant balloons added to the roster this year include: Astronaut Snoopy, Green Eggs and Ham, and SpongeBob SquarePants with his pet snail Gary.

Snoopy is the longest running giant character balloon in the parade, which has graced Big Apple streets for more than nine decades, according to organizers.

This year’s parade appearance marks Snoopy’s 40th flight.

Upper East Side resident Caroline Wheeler, 36, said that she has been coming to the parade with her cousin Byndee Carlson for the past five years.

“It’s a perfect day,” Wheeler said. “Last year was too cold. We’re elated to be here. We would come either way [even if the balloons didn’t fly.] it’s a good way to celebrate Thanksgiving. Everyone is is a good mood.”

More than 50 million people nationwide were expected to watch the televised parade from home.
