up to 1 week
If your melon is not-quite-ripe, you can 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.
If you have a dehydrator, you can preserve melon slices for a sweet winter treat.
