Seneca gets rougher than cayuga because its strait. If you have gotten blown off the north end of the lake with a north wind, i would suggest Owasco as an alternative. Its a nice little lake, and you can cover the whole thing in one day. Not as big so it doesnt get as rough. The launch at the north end in auburn is on the outlet with current, i would suggest launching at the south end (south shore marina) if you have a decent sized boat. The lake is only about 10 miles long so its not that much further of a drive. Take 34 to auburn and 38 down the lake.
