The main Jacksonville Florida winging spot is Huguenot Park. We are just entering our seabreeze season. June and July are pretty wingable every afternoon.
Southwest winds in the morning are offshore and perfect for prone foiling, if you’re not too proud to use a bigger foil and shorter mast for the small waves. Southeast seabreeze at 12 to up to 25 mph for 90 minutes or so in the afternoons is perfect for winging. It doesn’t blow all day like a Northeast wind in the winter. Instead you just get wind in the late afternoons. But it’s almost daily:
This chart is gusts, not daily averages… as the wind is light in the mornings. But it shows that July works surprisingly well.
As others have said, the surf is better North of Cape Canaveral in the summers. Where I live north of Jax in Florida, prone foiling is dictated by the tides on the beaches. As a relatively new prone foiler you can prone foil potentially twice a day, for 45 minutes to an hour each, either side of the lowest low tides. Dead low is usually too shallow to prone foil where I live, but you kind of have to learn each spot’s depth at low tide. One day’s tide cycle and you will figure it out.
The incoming tide hour of surfing is better than the outgoing tide hour. A mast as short as 65cm will give you 15 more minutes of foiling time without hitting bottom on takeoff at each of those tides on the smallest of days, which is a lot of days.
