Weird light at the beach huts

Just walking along Abersoch beach I came across this very strange looking light, which I had never seen or photographed before. Obviously I grabbed a quick snap shot before it vanished into thin air. I am not sure what created this or how but as soon as I saw it I knew I would try to record it. After capturing the above photograph I approached the weird light, but it disappeared. If anyone reading this knows what this is or has ever seen anything like this before please get in touch in the comments below…
