More Sharks in the Future! Thanks El Niño 2017

30 04 2017

We may need to change the name of this site to “Trestles Shark Crowd” in the future.

Over the last few years, the number of shark sightings has increased at Trestles and other local surf spots.  Shark experts say the increase in sightings comes with increased numbers of sharks off the Southern California coast due to improvements in the local fishery.   The good news is that after decades of efforts, the Southern California fishery has improved, reflecting a general improvement in many, though not all, portions of the local ocean environment.   The bad news is that means surfers need to become even more aware of their surroundings while taking advantage of California’s many great surf spots.  And, from time to time, we are going to see beach closures like other sharky areas of the world.

In the evening on Saturday, April 29, 2017, a woman was bitten by a shark while swimming with fins in the shallows of Church, that classic surfing area at the mouth of San Onofre Creek in the San Onofre State Beach, at the northern edge of San Diego County.  You can read more details in this Orange County Register article.   This article references remarks by Dr. Christopher Lowe, a shark researcher at California State University Long Beach.  Not only has Dr. Lowe been quick to remark in the past about the improvement of Southern California fisheries, but in this article he described to the reporter how El Niño conditions a couple years ago extended the amount of time juvenile sharks have stayed in local waters to eat and grow.

Assuming Dr. Lowe is correct (and he is considered an expert for good reason), more shark sightings are likely just around the corner.  The National Weather Service prediction center of the US National Oceanic and Atmospheric Administration (NOAA) predicted on April 13, 2017, that it is very likely an El Niño is going to form in Fall 2017.  As the water warms and reverses the effects of ocean currents, it will also be more likely that hammerhead sharks will show up at Southern California beaches, heading north from their usual foraging areas in warm Mexican waters.  And juvenile great white sharks will have less reason to head south to to those warmer waters after birth.  So, they will be hanging out even longer off our coast, increasing the number of shark sightings.

We are not predicting some sort of Sharknado, but we will likely hear more reports of shark sightings near our favorite surf areas.

So, tune into Trestles Shark, er Surf, Crowd.com for more info in the future.

[By the way, we can personally attest that only a small percentage of surf spot shark sightings are reported through the media.  Most surfers would say that sharks are just part of the ocean environment.  We enter their world every time we paddle out to catch a few.  So, why both reporting a natural occurrence.  Welcome to the Crowd Ms./Mr. Shark!]





San Mateo Creek Flows Again!

It’s been a few years, but the San Mateo Creek watershed “sponge” finally got full and started to overflow.  That is, all the soils upstream got full of water and started to seep/flow into the gullies that make up the watershed.  And, down to the creek bed and out to the ocean.

The last time it really flowed significantly was in December 2010; and flow it did, for almost six months.  It will be interesting to see how long it continues to flow with the off and on storms predicted over the next week or more.

Could the Southern California drought finally have broken?  Too early to tell, but it’s off to a good start.

Word is the creek broke out of the estuary/lagoon through the sand berm and out onto the reef at Uppers this morning.  You can see by the mud plumes in the ocean that it has been flowing for several hours at the time of these photos about 4:00 p;m today.

As happens with natural water courses, each time it breaks out, the flow “braids” to a new path.  We all got used to the “lagoon” that was dug out by the 2010 storms.  This time, the flow shoots straight out, dumping a lot of sand, and probably some cobbles, on top of the reef just north of what we call “Garcia-land,”  which is the north shoulder of the point. Wonder what new shape the bottom will take now.  Maybe a lagoon on each side of the point?  Maybe a  “north bay” and a “south bay?”
