In its fourth year, 'SurFeb' is a fun event born in the Sutherland Shire.
Participants challenge themselves to catch a wave or just jump in the water every day in February.
A record 500 participants are earmarked for the family-friendly, covid-safe fundraising event.
SurFebruary made sense for Cronulla sisters Jasmine and Grace Gosby, and they joined up to honour their grandmother, who was diagnosed with cancer the first year they took on the challenge.
Jasmine Gosby said everybody should do it because it's great exercise and it's fun and younger sister Grace said it wasn't hard to do because she was going surfing every day anyway.
SurFeb co-founder and cancer survivor, Jenna-Lea Clark, says the ocean's healing nature and surfing made it a perfect fit for Chris O'Brien Lifehouse.
"Being raised near the water, I know firsthand the positive and restorative impact of the ocean.
"For me, surfing is a healing ritual, and SurFeb is a way for the community to share in this beautiful, healthy pursuit while raising funds for cancer research."
In the past three years, it has raised more than $215,000 for cancer research. The 2021 target is $150,000, which would break the 2020 record and bring the event's total to almost $400,000.
SurFeb partners with Chris O'Brien Lifehouse and 100 per cent of donations raised go directly to this not-for-profit comprehensive cancer hospital. In particular, SurFeb 2021 funds will support vital research into the benefits of supportive care services for cancer patients.
Chris O'Brien Lifehouse board director, Gail O'Brien AO, says the SurFeb partnership is one of which her late husband would be proud.
"My husband was a man of science who came to have a holistic understanding of healing-his illness was a gift which taught us that cancer treatment isn't just medicine. It is a whole life approach."
'SurFeb' was Inspired by Jenna's battle after being diagnosed with an aggressive form of cervical cancer. Besides life-saving treatment, Jenna was given the opportunity to have another miracle baby, her son Vander.
After their cancer experience, Jenna and husband, Arron, teamed up with friends, Mike Durante and Krista Huebner, who share a passion for giving back, with a deep love for the ocean's transformative benefits.
Jenna said SurFeb represents overall healthy living - It's the ultimate win-win.
"The money raised will help improve the lives of people living with cancer, and participants will reap the mental and physical rewards of spending 28 consecutive days in the ocean."
