The last couple of mornings I've been hitting the water around 6:15-6:30 am. I'm up for swimming later in the evenings too when the kids are in bed (after 8 pm). I start from this location: https://goo.gl/maps/zg4VZQnvLTC2
There are showers there to rinse the sand off, and an area to lock up your bike. I swim parallel to the shore and am always within 50 m of the shore. The water is quite shallow at that distance, so you can stand if you want to.
I like to comply with international standards for open water swimming, so you need to leave that wetsuit at home. ha! Just kidding. It is pretty cold. I've been wearing a silicone swim cap, which is just a poor man's wetsuit. Wear whatever you want. I won't judge (out loud).
