This might nearly always work out OK for younger, strong and fit divers. Unfortunately, I am not as young, strong and fit as I once was and no longer take those risks. Now, when my primary charter cancels due to conditions, I simply thank them for assuring my safety. This gives me the opportunity for a nice bike ride with a stop at the Boynton inlet to check sea conditions. I frequently see large, breaking swells before continuing my peaceful ride.
Same here. I have no interest in pushing my luck just to get a dive in. There is A LOT to see and do in Palm Beach County. On the occasions when I get blown out, I'll just go hike, walk, kayak, paddleboard, bike, bird watch, etc, etc. Also, when possible, I try and coordinate my trips with decent BHB tides. I can't always do that, but I try. That at least gives me a solid shore diving option as well to fall back on.
