If you plan on using an avocado in meal preparation today, leave it unrefrigerated. If you intend to delay use of a ripe avocado for several days, then it is best to keep it refrigerated, but no colder than 40°F. Purchasing an avocado in “hard” or “green” condition means that the avocado will normally take 3 to 5 days to ripen unrefrigerated. If you’re buying several at a time, store some of your hard green avocados for up to 10 days in your refrigerator to delay ripening. By using this method you can rotate your avocado inventory to ensure you have a ripe avocado every day. Enjoy!
