Watermelons are generally believed to have originated in Africa several thousand years ago and to have traveled over time from Africa to Asia to Europe to North America. Their arrival in Asia and the Middle East is believed to date back to approximately 900–1,000 A.D., and their arrival in Europe is estimated to have occurred in 1300–1400 A.D. It was not until Europeans began to colonize North America that watermelons arrived in what is now the U.S.
Today, over four billion pounds of watermelon are produced each year in the U.S. About 85% of watermelons are purchased in fresh form by consumers. Although there is some watermelon production in virtually all states, about three-fourths of all U.S. watermelons are grown in Florida, California, Texas, Georgia, and Indiana. On an average, per person basis, we eat over 15 pounds of fresh watermelon each year.
On a global basis, China is by far the largest watermelon-producing country and accounts for over half of all world production. The European Union countries, Iran, Turkey, Egypt, Brazil, and the United States are the next largest watermelon producers, but each produces less than 5% of the world total.
