The time an avocado takes to ripen depends on how far we are through the season and the weather.
July /August they can take up to 10 days to ripen at room temperature.
Sept/Oct 8 days
Nov/Dec 7 days
Jan/Feb 6 days
Mar/Apr 5 days
These are estimated timeframes and it pays to keep an eye on your avos. The best indication is the darkening colour and softening of the avocado.
A trick to ripen avocados is to store them at room temperature with an apple, kiwifruit, or a banana. These fruits produce ethylene which will cause the avocado to ripen faster. You can also remove the stem to speed up the ripening process. As they get closer to ripening store them in the fridge and remove the day before you need them.
