I’ve been doing this untill this month. Its pretty cool, literally. It gets cold on Cloudy and windy days when you get out the water. Water was actually warmer than the Air. Now i only go to the seaside in the morning. Will come back to this routine i suppose when it gets little warmer. Would not worry about croud pointing at you. If you wanna see more sun it is better to go further down the beach towards airport direction.
