Sept. is a dead month and lots of places are closed for slow season, but the Diving conditions are great.
My dive shope is just up the beach from Belizean Shores,(You can see our big flag on the dock). We will be closed in Oct but will dive up to Sept 30th.We pick up and deliver from the dock at Belizean Shores daily.
