                                According to the Watermelon Board, an average large watermelon can weigh around 9,071 grams, or 20 pounds, but this figure can vary dramatically depending on the variety and growing conditions. The weight of a 'normal' watermelon is not a fixed number, as different types of watermelons are bred to be different sizes.
