July 8, 2008. Yea! A small but strong swell from Bertha will arrive at our beaches overnight Thursday. Winds will be light S/SW turning more SE in the afternoon and generally staying below 10 knots through the weekend. SURF: Late Thursday afternoon we may start seeing a trickle of Bertha swell, but Friday looks to be the day. Should be chest high at least. Sat and Sunday will see solid waist to chest. DIVE: Dive before Friday! The energy from Bertha's swell may stir up the bottom, especially at the reefs close to the beach. South beaches may be less affected..
