BBC weather for Leeds/Ilkley has it banging it down until 9, then clearing up with a 15mph wind from West.
Can add at least 5-10mph for height, so it could be a tad breezy from Baildon moor summit up to Ilkley moor and then across the top to Buck Stones.

Hopefully though, the BBC are right and it won't be pi$$ing it down. Wind+Rain+Ilkley Moor could be a bit depressing after about 12miles.
