Gwithian is one of the UK's most celebrated kitesurf and windsurf wave spots — miles of golden Atlantic-facing sand on the northern shore of St Ives Bay, backed by dunes and reliably windy. In a north-easterly, it produces long, clean down-the-line waves that draw kiters from across the South West. In a southwesterly the wind is cross-shore and the beach catches good swell.
The sheer size of the beach means there's usually room to spread out, but it's busy with surfers in summer and the lifeguard zones must be respected at all times. The Kernow Kitesurf Club (KKC) is very active here and a good source of current conditions.
Low to mid tide is the sweet spot. The beach narrows significantly around two hours before high tide and becomes unsuitable — gusty behind the dune line and backwash in the waves. At low tide the sand opens up and launch space is plentiful, though the tide can run up to the shingles making getting on and off the water more awkward.
Cornwall Council's Gwithian Towans car park (275 spaces) is the main option. From 1 April to 31 October: up to 1 hour £3, 2 hours £5.60, 4 hours £8, 24 hours £12. Parking is free November to March. Season and rover tickets available; pay via JustPark or BuzzPay.
