The mayfly hatch always seems to slow the walleye fishing in the Western Basin, primarily within 8-10 miles or so of the shoreline and around the Islands. Once the hatch diminishes and then ends (late June diminishes, early July ends) walleye are once again caught in the Western Basin closer to shore and around the Islands. There are good numbers of walleye in the Western Basin right now, it's just catching them that is more difficult. This coming weekend will probably still be slow, but you can find walleye and catch them if you find the right spot and lure presentation. If you have a viable choice this coming weekend, yes, I'd fish the western part of the Central Basin - out off Huron and even Cedar Point / east of Kelleys Island. You'll most likely have an easier time catching walleye there.

The only perch action I've heard of was last week off the west side of the Camp Perry range. Someone reported they did pretty well, but I don't remember exactly where.
