Nobody is stupid enough to think that Irma is going to be fun but way before it hits and after it passes, there might be tremendous surf for people who are experts only. Expect huge conditions and dangerous riptides.
Im guessing that Wednesday/Friday of next week but who knows.
If if nothing else, one can see pictures of surfers surfing Irma on the internet.
If you want to go watch the ocean's meanest personality, stay the hell away from the water. I have witnessed people do stupid things when the ocean is sick, and people either get wet, injured, or killed.
Ive seen HUGE swells literally explode on jettys that have unknowing thrill seekers standing on top, roiling water tumbling over them. One year (I think it was in New Hampshire) a bunch of people were washed away and never seen again. It happens all the time in Hawaii to tourists and locals alike.
