In the show, Wheezie is supposed to be younger than her older sister Sarah, who’s 16. Even so, in real life, Julia is 18 years old playing a 13-year-old. There’s a chance that future seasons of Outer Banks could bump up her age with the hopes that viewers won’t notice, so Wheezie can be more central of a character with Sarah.
But for now, Julia is playing a character significantly younger than she is IRL.
And Julia still does everything that other average teenagers do. Her Instagram is full of photos from the Outer Banks set, but also selfies with friends. And she shared multiple posts with pictures from her high school prom. She also graduated in 2021 and was quick to share some pictures from that too.
