Infinity Sport’s mobile training ground on the south Kent coast — suited for mid-tide coaching with deeper water access for hydrofoil progression. Very broad wind arc (S, SW, SE, E, NE, N). W is a no-go. Kiting is not advised 3 hours either side of HW; wing/hydrofoil is best within 2 hours after HW. Public beach users have priority — no kiting past the coffee van. Beware submerged groynes at high tide. Parking, toilets, shower, and a coffee van on site at St Mary’s Bay. The village of Dymchurch is a short walk north with shops, cafes, and The Ship Inn. School: Infinity Sport Kitesurfing.

Pick a past day to compare three things: the forecast we published (frozen before each hour, never revised afterwards), the wind that actually happened (Open-Meteo reanalysis, hours 05:00–21:00 UK), and what the live weather stations near the spot actually recorded (amber, from 2 Aug 2026). You can go right up to today — today shows the forecast and the live stations; the reanalysis for today lands tomorrow morning.
