It could be redberry mite. This condition prevents berries from ripening uniformly and tends to affect late-bearing varieties such as Chester, Triple Crown, Navaho, and Apache. And, yes, it could be due to the hot weather. The bushes probably get plenty of moisture if they are near the creek (and it has not dried up with the lack of rain). We hope this helps.
