A good watermelon should feel heavy for its size. Watermelons consist of a lot of water, and the heavier ones tend to be juicier and more flavorful.
4. Tap the Watermelon
One of the oldest tricks to test the ripeness of a watermelon is to tap it gently. A ripe watermelon will create a deep, hollow sound, while an unripe one will sound more dull. The hollow sound implies that the melon is full of water and ready to eat.
5. Check for the Field Spot
Examine a yellow field spot (the area where the watermelon sat on the ground during ripening). A ripe watermelon typically has a soft, yellowish field spot. If the spot is white or green, the watermelon may not be fully ripened.
