When you flip a watermelon upside down, you’ll see a colored spot known as the field spot. If the field spot is YELLOW, that means the watermelon has been spending more time on the ground on the vine ripening, therefore it should be a sweeter tasting watermelon. If the spot is WHITE then that suggests it did not spend as much time on the ground and ripening on the vine, and possibly picked too early, and the taste may not be as sweet.
