Soak wooden skewers in water for at least 20 minutes to prevent burning.
Thread the watermelon, banana chunks, strawberries, kiwi pieces, pineapple, and mango onto the skewers, alternating fruits for a colorful presentation.
Sprinkle the fruit skewers evenly with cinnamon.
Preheat the grill to medium-high heat.
Place the skewers on the grill and cook for 12–15 minutes total.
Rotate the skewers every 5 minutes to ensure even grilling and attractive grill marks.
In a small bowl, whisk together the honey and fresh lime juice.
During the last 5 minutes of grilling, brush the Honey Lime Grilled Fruit Skewers generously with the honey-lime mixture.
Remove from the grill and serve immediately while warm.
