How long do I need to wait to go swimming in the ocean after a tummy tuck?

I am 6 weeks post op from having a tummy tuck, lipo of the flanks and muscle repair. My incision is healing well. There are a few tiny spots right at the pubic line that have opened a tiny bit, but are not problematic. Is it safe to go swimming at the beach? I also have been wearing my binder 24/7 and would like to take it off for a couple of hours.
