Fig splitting is usually the result of sudden changes in pressure brought on by cool temperatures, high humidity, or excessive moisture as the fruit matures. It may also result from excessive pollination and the growth of too many developing seeds. However, this is not considered a major problem.
While figs do not technically continue to ripen once picked, they do still soften and sweeten for a few days after they are picked, which is what you really want anyway. Try picking the fruit a bit before they feel they are ready and put them in a paper bag for a day or so after this. You should still end up with the juicy, sweet fruit you want without the splits.
