Friday's outing comes after Harry delighted rugby fans with a surprise video appearance to talk about the sport's importance.
The Duke said the "passion and enjoyment" of sport can bring comfort to people in the "isolated" times we live in. Fans were delighted by his appearance, and many were quick to point out the difference California sunshine has had on his appearance.
"He is tanned. Must be the Cali sunshine," tweeted one social media user. "Prince Harry is glowing, lots of loving care and California sunshine," said another, with a third adding: "Looking good Prince Harry."
