swell:regaurdless of the surf reports 99% of the time the launch is flat. anything from the W-NW under 11 sec and over 4-5ft usually has me packing light or not launching at all

....longer interval from the same direction (w-nw) will not really effect the launch even if it's 7-10ft at scripps. in most of our fishing kayaks with a little practice, 3-4ft is a piece of cake.
wind: this is the limiting factor, anything over 15mph is a little rough in the hobie and it starts getting difficult to fish. if there are 15+mph S winds I wont fish. Strong E winds (offshore) schedualed to blow all day keeps me off the water too. My favorite wind conditions are light E in the morning shifting to light W winds in the afternoon
