First there's the magic of place... Of course, the secret spots up and down the coast come to mind. Places with shark lore, epic waves, tragedies. There are smaller miracles too. For example: I bought most of my surfboards through Craigslist. Every place I've met someone to buy a board has become a magic spot for me.
I highly recommend you try meeting someone on your commute route next time you buy a surfboard. I bought my last board from a guy I arranged to meet at the BART station parking lot near my house. Now every time I come home, the magic reminds me that there might be waves tomorrow morning.
Then there's the magic of time, which seems extremely elastic when riding a wave. Everything slows down. Why? Because my heart and CNS is on overdrive? Or so I can enjoy the ride? Who knows? Also, photographers talk about a magic hour or golden hour when the sun is just right. Surfers know that the early AM hours are often best for waves because wind tends to stop.
Magic things... magic surfboards. I'm lucky enough to have one. It catches waves in all conditions. Board shapers love to discuss the magicness they've encountered over the years.
It's all true. Every last bit.
