How to Store. Let a not-quite-ready cantaloupe ripen at room temperature for up to 2 days (keeping it in a closed paper bag will speed up the process). Refrigerate a whole ripe melon for up to 5 days. For cut wedges of cantaloupe, cover the surfaces and refrigerate for up to 3 days. (If possible, leave the seeds intact. They prevent the flesh from drying out.) Cubes without the seeds will last 1 to 2 days in a resealable container in the refrigerator.
