Sura is based in sunny San Diego, California where she teaches freediving year round amongst the kelp and sea lions in the Pacific Ocean. She has an extensive freediving background including Emergency First Aid and scuba rescue training, instructing people from all walks of life about the science behind apnea and how our bodies adapt to depth. At the same time, she began mermaiding and performed for various events around the world including the Escondido Renaissance Faire, Wands and Wishes, Mermaids Make Waves, and Swim Brayv where she advocates for water conservation and swim safety.
She currently teaches both mermaiding and freediving, taking the best of both worlds and merging the two to educate all of her students about safety, proper technique, mindfulness, but most importantly to believe in one’s own amazing capabilities!
Testimonials
On Mermaiding...
"Christine, aka "Mermaid Sura", was an absolute pleasure to learn from. I was enrolled in her PADI Mermaid & Advanced Mermaid combo course, and for starters, she is incredibly communicative. What I loved in particular is the fact that she's a master freediver and applies a lot of that knowledge/experience to her mermaid courses, so it isn't "fluffy" by any means. She's very educated about the science behind apnea, uses the terminology, and is clearly passionate about it. All in all I highly recommend this course - or any course taught by Mermaid Sura - and I felt like I walked-away a better waterman/mermaid performer, as well as with a new friend. "

On Freediving...
"I booked a private coaching session with Christine and it was awesome! She’s very knowledgeable, friendly, and professional, which allowed me to feel comfortable in the water with her while simultaneously learning and having fun. She took videos throughout the session and sent them to me with detailed notes, including techniques I need to work on, which I really appreciate. If you’re thinking about booking with her, don’t hesitate!! Thanks Christine!"

On BOTH Freediving and Mermaiding...
"Training with The Surreal Sirena has been a truly transformative experience. As a certified PADI Freediving Instructor, she embodies a rare combination of professionalism, deep expertise, and a calm, inspiring presence that immediately puts her students at ease.
From the very first session, it was clear that Christine approaches freediving not just as a sport, but as a profound connection between body, mind, and the ocean. Her instruction is clear, methodical, and deeply rooted in safety—an essential quality in a discipline that demands both physical and mental discipline. She is incredibly knowledgeable, and her ability to explain even the most technical aspects of freediving in a way that is easy to understand is remarkable.
One of Christine's greatest strengths is her patience. She takes the time to understand each student’s pace and comfort level, creating a supportive and non-judgmental learning environment. Her calm guidance and thoughtful encouragement helped me build confidence and push past personal limits I didn’t realize I could overcome.
What truly sets The Surreal Sirena apart is the atmosphere she creates—one of trust, encouragement, and deep respect for the underwater world. Whether guiding breathwork on land or offering gentle reassurance during a dive, she brings a grounded and intuitive presence that elevates the entire experience.
Beyond technique, Christine instills a sense of reverence for the ocean and the art of freediving. Her passion is evident in every interaction, and her ability to inspire while prioritizing safety makes her an exceptional guide for anyone looking to explore the depths—both literally and within themselves.
I wholeheartedly recommend The Surreal Sirena to anyone seeking not just a freediving instructor, but a patient, knowledgeable, and certified PADI professional who brings soul, skill, and serenity to every dive."
