Flat until ten, choppy until four, flat again after. The two hire windows are not arbitrary.
People ask why we sell four hour windows at seven and at one rather than letting them take a board out whenever they like. The answer is the wind, and it runs to a schedule here.
The lagoon inside the reef is glassy from first light until about ten in the morning. Somewhere between ten and eleven a breeze fills in from across the atoll, and by noon there is a chop on the water that makes a paddleboard genuinely hard work and takes most of the pleasure out of a surf. That holds until about four, when it drops away again and the last two hours of light are often the best of the day.
So the morning window is seven until eleven, which is the glass. The afternoon window is one until five, which starts in the chop and ends in the good part, and it is cheaper than a full day for that reason.
If you are only going to get in the water once, get in before ten. If you are here for a week, do a morning window on your first day, see how the wind behaves while you are standing in it, and then book the rest accordingly.
The far reef is different again and depends on the swell direction rather than the wind. Ask at the counter on the day. We are looking at it out of the window anyway.
