How Much Does An Average Watermelon Weigh?

While the watermelon’s weight varies, the average weight ranges between 20 to 25 pounds (between 9 to 11 kilos). In turn, these average watermelons generally yield 14 to 18 pounds of edible fruit leaving the remainder of the weight in the rind. The largest melon recorded to date is 350 pounds.

Factors That Influence A Watermelon’s Weight

  • Genetic Factors: Watermelons will all weigh differently even if they’re of the same species, grown on the same soil, and harvested in the same weather conditions – genetic composition of each watermelon is different and ultimately influences the weight. Individual genetics among watermelon varieties result in such different sizes and weights.

Apart from the weight, watermelon’s genetics also influences its physical appearance – color, shape, and more.

  • Environmental Factors: When considering the weight of watermelons, it is important to also consider environmental factors. There are certain environmental conditions that are favourable for growing watermelons. If the watermelon is grown in an unfavorable environment, it won’t be as healthy as they should be and the weight won’t be up to standard.

Environmentally, watermelons depend heavily on sunlight and rainfall. When they can’t get these natural factors to grow, we use technology (artificial light or electricity) to grow the watermelons. However, your expectations of watermelon quality will likely change when you purchase a watermelon from out-of-season.

  • Human Factor: When talking about topics such as this one, we can not rule out the human factor. One of how humanity impacts watermelon shape is through farming. Farmers who grow watermelons are responsible for watering the plant and ensuring it receives sunlight and other essential nutrients like fertilizer.

Watermelon by an irresponsible individual will not be as nutritious as expected. When well-tended, the watermelon plant can produce tasty and properly sized fruit. So if you ever see any scrawny-looking watermelons, one of the reasons could be neglect on the part of the farmer. Humans can also manipulate natural factors like soil with fertilizers and other ingredients to aid in plant growth.  

These differences are also due to the factors that include soil, water, pollination, and weather conditions. They will determine the watermelon’s resistance to disease, color, and ultimately the weight.
