July is the smallest stretch of the Welsh year. Llangennith needs a westerly swell to do anything at all and July often does not send one, so a fortnight can pass with nothing on either side of the peninsula.
For a first week that is the point rather than the problem. Langland Bay is the sheltered side, it works across the whole tide, and in July it produces exactly the waves somebody learning wants: small, repetitive and warm enough at 17°C to stay in for two hours. Every school on the peninsula is running and the Welsh summer holidays have not started.
Set against that, the beach is busy and the parking is worse. Llangennith has three miles of sand and room to spread out; Langland is one bay and does not.
