To Surf or Not to Surf After the Rain

Hillsides above Montecito charred by the Thomas fire gave way after heavy rainfall on Jan. 9, resulting in mud and debris which were responsible for over 20 deaths and destruction of 137 homes.

The affected community was almost completely cut off from the surrounding areas. Thousands of residents were stranded in their homes without power, some were blocked by mud too high to open their doors while others were unable to navigate the flooded roads. Routes 101, 192, and numerous residential streets were flooded or blocked by debris, making them completely impassable. Multiple fires erupted after gas lines broke.

Rescue operations began almost immediately, and community driven relief stations as well as donation efforts to help displaced residents sprang up shortly after. Montecito and Santa Barbara as a whole have not fully recovered from the disaster, but the progress made is inspiring.

Almost two weeks after the mudslide, life is starting to return to normal for some Santa Barbara residents living outside the area immediately damaged by the debris flow. At this point, many are starting to ask themselves questions that might seem petty in the face of such a disaster.

Is it worth taking the train to Los Angeles to see that show I bought tickets for this weekend?

Is there really a ferry going from Santa Barbara to Ventura?

Where in the world is route 166?

But most importantly: should I go surfing?

On one side of the argument are the good conditions and solid waves that usually follow a significant storm in Southern California. But on the other side are the contaminants — like brake dust, oil, and dog poop — that rain washes into storm drains and eventually into the ocean.

In most cases though, the answer is almost always to take your chances and paddle out.

Surfing differs from most other outdoor hobbies because it is almost completely dependent on conditions outside human control. Unless you’re Kelly Slater and have your own wave pool, you can’t return to the same waves every day like you can return to the same basketball hoop.

The risk of becoming sick after surfing post-rain is a real threat, but surfers risk their health just the same as any other athletes do. Unless you’re surfing waves well overhead or at a break with hidden rocks and dangerous currents, drowning doesn’t cross a surfer’s mind. Injuries like torn ligaments, broken bones, and concussions are much less common than they are in traditional ball and stick sports.

Surfing is also arguably much safer than similar sports like skating or snowboarding. There is no concrete to slam into, no jumps to land short on, and no rails to hit. So, why not take the risk of paddling out after rain?

Researchers from the University of California, Berkeley, the Southern California Coastal Water Research Project, and the National Surfrider Foundation found that “the risk of getting sick after swimming in the ocean is about 25 per 1,000,” according to the San Diego Union Tribune. “That number increases to 30.2 per 1,000 following rainy conditions.” Three days after the rain, the risk of catching an illness returns to almost baseline levels.

Especially in Santa Barbara where rainstorms are few and far between, taking a chance on your health a few times a year to score waves you might not get until the next winter is worthwhile. Setting aside pre-existing conditions like a large, open wound that could get infected or an unusual amount of pollution, surfing after the rain is the right decision.

The level of dirtiness needed to keep core surfers out of the water is a grey area, but at a certain point everyone knows the line has been crossed. The current conditions at most beaches in Santa Barbara county are definitely beyond the point of “too dirty to surf.” According to the county, levels of “fecal coliform” are more than 60 times the state health standard.  

Surfing in water contaminated with fecal-anything is disgusting, and the dangers aren’t worth surfing in those conditions. However, contaminants like that aren’t common and shouldn’t influence the decision to surf or to stay dry. It’s ultimately up to each surfer to make the choice, but for people who are truly committed, it’s a lot harder to say no than yes.


  1. Dear Tanner, Science & Tech Editor:

    I was surprised to see your article minimizing the health risks of contaminated ocean water exposure, especially in our current situation where large amounts of contaminated mud continues to be dumped at Goleta Beach daily. Are you aware that our Santa Barbara County Public Health Department has CLOSED the ocean water at Goleta (and adjacent campus beaches) since January 11, 2018, and keep renewing it weekly since then?
    As a science editor, I would hope you would rely on the authority of Public Health experts and the posted data of our ocean water testing results which are currently quite alarming. In Student Health we are seeing surfers who have contracted illnesses from our local ocean, and have alerted students that any use of our current ocean water is inadvisable. I am sorry that students may be mislead by your bad advice to continue surfing in this water.

  2. Dear Mary,

    My article was not an attempt to minimize the health risks of exposure to contaminated ocean water, it is an opinion and nowhere in the article did I state that it was safe to surf after rain. I tried to include valid points from both sides of the argument, including a study detailing the risks of surfing after rain.

    I am aware that local beaches have been closed due to water quality, which is why I stated that “The current conditions at most beaches in Santa Barbara county are definitely beyond the point of “too dirty to surf.” Immediately following that is a link to the press release from the county with specific bacteria levels. Later in the article, I stated: “Surfing in water contaminated with fecal-anything is disgusting, and the dangers aren’t worth surfing in those conditions.”

    Also, according to KEYT (, “The following beaches will be open:
    Gaviota State Beach
    Refugio State Beach
    Leadbetter Beach
    Sands Beach at Coal Oil Point
    Guadalupe Dunes
    Jalama Beach”

    Nowhere in the article was I encouraging anyone to surf immediately following the rain, and all of the data and evidence I provided would actually suggest that entering the ocean after the rain is a bad idea. The article was meant to say that for people who are committed surfers, getting an illness from surfing in dirty water is a necessary risk just like a baseball player risks taking a fastball to the head every time they step into the batter’s box.
