Spend a week every summer in Eastern Ontario (1000 Islands) to escape the North Carolina heat but can't tell ya much about Nova Scotia summer water temps. However if you are in NS until early Sept check out a concert by local surfer/Blue noser and rocker Matt Mays with his side kick from Montreal Sam Roberts (rock star in Canada). Travel north up to Cape Breton also. Canada taxes, gas and about everything else is higher than the States so be prepared to fork out a little extra cash. May also want to check out Great Big Sea - popular Canadian Maritime band. Also donuts at Tim Hortons a must!!
Info on Matt Mays and Sam Roberts (Band) concert for Austism:
4/3. Bring gloves and booties and probably some kind of hood too.
