Watermelon
As long as this fruit hasn’t been cut open it’s best to be stored outside the fridge. Studies done by the U.S. Department of Agriculture (USDA) showed the nutritional value of melons can be adversely affected by colder temperatures. Only melons that have been sliced should be refrigerated. Those that are sliced, however, should be securely covered.
Oranges
Citrus fruits are high in acidity and should be damaged by temperatures that are too cold. The skin also can become dull and spotted when stored within the fridge. Since oranges have such a thick, tough skin they’re doing well in warmer environments.
