Mike my breba ripened mid August and I thought they were excellent. Very sweet and juicy and none split.
Last year none of the main crop split, but I can't remember if it was dry or rainy at that time. I'm still waiting for this year's main to ripen. My tree is planted in ground so if it rains alot when they're about to get ripe I won't be able to do much about it, just sit back and watch them explode.
