What the sources say

FoodKeeper gives watermelon 1 to 2 days in the pantry from the date of purchase, or until it is ripe.1

In the refrigerator it lists 3 to 4 days, and in the freezer 12 months.1

FoodKeeper does not say whether its refrigerator time is for a whole or a cut watermelon.1

The FDA names half of a watermelon as one example of pre-cut produce, and says to choose only pre-cut, bagged or packaged items that are refrigerated or surrounded by ice.2

Iowa State University Extension lists watermelon as a non-climacteric fruit, unlike cantaloupe and honeydew, which it lists among the melons that keep ripening after harvest.3

Non-climacteric fruits reach their peak sweetness and flavor on the plant and stop developing once harvested, so they may soften from decay but will not become sweeter or more flavorful after picking.3

Iowa State says these fruits are best stored in the refrigerator shortly after harvesting, kept away from climacteric fruits, which go on releasing ethylene gas in storage.3
