There’s a particular kind of magic that happens in October in Rocky Point, and it has nothing to do with pumpkin spice. It’s the feeling of a town exhaling. The summer heat finally lets go of its grip, the streets start filling back up as families return from wherever they scattered for the hottest months, and if you stand on the beach at just the right hour, you can feel it – that in-between. Not quite summer, not yet winter. Not quite empty, not yet packed. Just… hovering, gorgeously, in the middle. I love October!
Turns out, the Sea of Cortez feels it too.
What’s Happening Under the Surface
While we’re up here enjoying cooler mornings and warmer welcomes, the water off our coastline is going through its own quiet transformation. The summer’s red tide algae – the reason locals have long followed the old “only eat shellfish in months with an ‘r'” rule – starts to clear out as temperatures drop. And just like that, shrimp season reopens. Late September kicks it off, and by October the boats are back, hauling in Peñasco’s famous big blue shrimp fresh off the docks. If you’ve never had shrimp this close to the source, October is your month.
Here’s something most visitors don’t expect: October is actually a good month to spot a whale shark. We had our own encounter out on the boat not long ago – something enormous moving alongside us, easily bigger than the boat itself, its back covered in that unmistakable constellation of pale spots. Whale sharks are gentle giants, filter feeders with zero interest in bothering swimmers or boats, and they’re surprisingly unbothered by company. It’s one of those moments that stops a conversation mid-sentence. The bigger whales – the grays, the fins, the humpbacks – usually aren’t part of our October scene here in Rocky Point; those tend to show up later, around January and February. So, think of October as whale shark season locally, with the “big whale” show still a couple months off.
And then there’s the phenomenon most people have never even heard of: bioluminescence. The folks at CEDO (the Intercultural Center for the Study of Deserts and Oceans, right here in Puerto Peñasco) call it “sea sparkle” – tiny dinoflagellates that glow blue when the water’s disturbed, fed by the same plankton blooms that draw the whale sharks in. Under the right conditions, waves rolling in look like streaks of blue light, and footprints in the wet sand spark as you walk. It’s unpredictable, no guaranteed schedule, and I’ll admit my own bit of envy here – my friends caught it on camera on a beach walk last Fall, and I completely missed it. But according to CEDO, fall and winter tend to be when it shows up most in Puerto Peñasco, so if you’re out at night in October, keep your phone charged and your eyes on the waterline. You just might catch what I didn’t. (My own Glowy would be jealous – more on that below.) More to come on Bioluminescence next month!
A boat trip out toward Bird Island (Isla San Jorge) rounds out the underwater side of October – dolphins riding the wake are nearly guaranteed, and the island itself is full of sea lions, still energetic from this year’s pups.
Meanwhile, Back on Land
The town isn’t just waiting around for the water to do its thing. October brings out some of Rocky Point’s most delightfully weird and wonderful local color.
Mark your calendar for October 24th, when Puerto Peñasco celebrates the 10th anniversary of the Charanga soapbox car race – a gloriously homemade event where gravity-powered, hand-built racers zoom down the hill with zero regard for dignity and maximum regard for fun. If you want to see this town’s creative, playful spirit in one afternoon, this is it.
And if you’re around on a first or third Saturday, don’t miss Mermaid’s Market at Shrimp Plaza, where local artisans sell handmade crafts, jewelry, and food – proceeds support DIF, a local nonprofit focused on family welfare. It’s easy to spend an entire morning wandering, chatting with vendors, and walking away with something you didn’t know you needed.
October also happens to line up with fall break for a lot of Arizona schools – districts stagger their weeks differently, so check yours, but if your family’s got a random Tuesday off in early-to-mid October, this is a very good place to spend it.
October in Rocky Point isn’t a month that shouts for your attention with big headline events. It’s quieter than that – an invitation to notice the in-between. The shrimp boats returning. A whale shark gliding past, bigger than your boat. The water lighting up blue if you’re lucky enough to catch it. A homemade race car wobbling down a hill to cheers. A market table where someone’s grandmother is selling jewelry she made by hand.
This is the town at its most honest – not performing for a crowd, just being itself, mid-transformation, and inviting you to be part of it.
So come find your own version of the in-between. Bring your appetite for shrimp, your patience for whale watching, and your camera for whatever the water decides to show you. I’ll save you a seat, meet me at the beach.
P.S. — If our water’s moods fascinate you as much as they fascinate me, I’ve got two books that might be right up your alley: The Sea That Wouldn’t Stay Put, a children’s flip book on Rocky Point’s wild tides, and The Sparkling Adventures of Glowy the Fish, a children’s picture book series about bioluminescence. Both are on Amazon.
