Both can work.
But neither should be judged simply by how strong the wind is.
For beginners, the ideal learning environment depends on a combination of
wind strength, water conditions, space, equipment, instructor support and the possibility of training consistently.
Preá has one major advantage: continuity.
During the main season, students can often train over consecutive windy days rather than taking one lesson and then waiting several days for the next usable conditions.
The main beach is ocean rather than a perfectly flat beginner lagoon, so students also begin adapting to real riding conditions relatively early.
That can make the first water starts more demanding than learning in perfectly flat water. But it can also produce a more adaptable rider later.
Phan Rang can also work for learning, but
spot selection becomes particularly important. Strong wind and reef-influenced conditions at some locations mean beginners shouldn't simply choose the same spot as experienced riders because it looks good on Instagram.
So which is better?
If the goal is simply to achieve the easiest possible first water start, the answer depends on the exact training spot and conditions. If the goal is to build toward
independent riding over several consecutive training days, Preá is a very strong option.
For riders starting from zero, you can see how
kitesurfing lessons in Preá are structured from first kite control through to independent riding.
