Good years are not shown here: this spot has no complete per year values, because the two models drift apart over the years. x in 10 reads: of all 10 day trips that started in that month between 2017 and 2025, x in 10 got at least 5 kite days. We cap the figure at 9 in 10 because wind is never a promise. Best hours: the hours from 10:00 on when the wind most often reaches 12 to 35 knots. Rain day: 1 mm or more of rain.
