Good to hear that, please pass it along. I am hearing about some new threats in far flung places due to incidents. It is such an unnecessary hassle for riders and the sport also it is fairly easily avoided.
They aren't that wide and with the high coastal ridge and development inland have some fairly uneven wind (gusts and lulls) due to wind shadow. Also, access is fairly difficult. There is no parking or real public access along the eastern side and the west is fairly heavily developed. I don't know of anyone that kites there these days. I wouldn't recommend riding there.
For sheltered water you would do better in Biscayne Bay or off the Florida Keys to the south or off Sebastian State Park to the north.
Good, it is unlikely you will have much more than 23 kts or much over 5 ft. seas to deal with. It is possible but not particularly likely. The closer it is to onshore and at certain tides, the harder it can be to get out through the break. It can come down to having enough kite power, strong edging and timing passing through lesser waves and keeping your balance as you pass over them. It is good to weight your back foot to avoid digging into them by accident. The nature of the waves will change with water depth and the tide so waiting can help sometimes. As I said, the waves will drop with each inlet you pass moving southward. So if you find it too difficult to get out in LW you could head to NE 15 ST. in Pompano.
I haven't heard much about large migrating sharks for a couple of weeks off here. They usually taper off sometime in March.
The sea taxi guys run you out there, anchor and stand by while you ride. I put up some past article links below. In good wind it would really be worth your while to do it.
All the coastal areas work for side shore winds. That direction also usually has the lowest seas as well. You want to be careful about losing a board although usually the waves will bring it ashore eventually.
