    Florida is the only US supplier of watermelons from December to April. Florida watermelons are harvested throughout the year, although the vast majority of production is harvested from May to July (Bertelsen et al. 1994). In 2020, Florida growers planted 26,300 acres of watermelons and harvested 25,200 acres. The average yield was 38,080 pounds per acre for a total production of 958.65 million pounds. Harvested acreage during the past decade has ranged from 19,700 acres harvested in 2014 to 25,200 acres harvested in 2020 (USDA/NASS 2021).
