Slice the watermelon into 1/2-inch thick rectangular strips using a sharp knife on the cutting board. Place the slices in a large mixing bowl.
In a small bowl, whisk together coconut milk, lime juice, and honey until well combined and fragrant. Pour the marinade over the watermelon strips, tossing gently to coat evenly. Let sit for 5 minutes to absorb flavors.
