I don't know where you going to go on the coast. Its looking slightly bigger, waist high kind of average over the weekend and supposedly carrying into Monday morning with a slightly larger size.
4 hours is a looong drive. But, Monday does look like it could be relatively fun. Fun being in the 2-3-4' range with some small SE ground swell action. Keep in mind, the tides are especially important with the longer period swells.
definaltey wait it out and see what there calling for on sunday.. but if there still saying some tummy highs and better for monday then id say do it.. also see what tuesdays gonna do then maybe make a two day trip out of it so your not driving so far just for a few hours
wednesday i think we're getting something off the lakes giving us a NE swell for wednesday. so that might make your trip 3 days now.
southern de still looking good for tommorow and keeping its decent size through out the week.. hope to see you back here tonight or early tommorow
