how to store watermelon
Store uncut watermelons at room temperature. Store uncut watermelon at 55Â°F to 70Â°F (13Â°C to 21Â°C). Whole melons will keep for two weeks at 60Â°F (16Â°C), 7 to 10 days at average room temperature and up to a week in hot weather. Store it too long, and it will lose flavor and texture. Chill the watermelon before cutting.
