Rely on ACT or retake SAT?

I just got a 31 on my April ACT (32 E 30 M 33 R 28 S) and I am super ecstatic, being as that is the average or higher for my in state schools (UC’s). I had also taken the SAT last October and had gotten 1880. I am retaking that in June, but was wondering if I should retake the SAT or ACT this fall. I know its preemptive, but it’d be nice to have a plan now. Thanks for your input.
