Cold water swimmer

Swimming in the sea, all year round

Swimmers wading into the sea at first light

I’m Siobhan. I make short videos about swimming in cold water through every season, and I sell a swim journal, kit lists, a year guide and two video courses.

  1. Keeping warm after the swim: my flask and robe

    The robe, the flask, the hat and the order I do things in when my hands stop working.

    A pool the tide leaves behind, and why it is my favourite place to swim slowly.

About

About me

Five years ago I walked down to the sea one grey January morning and got in up to my knees. I lasted about forty seconds and have been going back ever since. Now I swim most mornings from the rocks below our house, in a hat, a robe and an old pair of gloves.

I film what I learn through the year: how to get in, how to get warm, what to wear, when to stay out. What I sell is what I carry in my bag: a swim journal, a few plain lists and guides, and two video courses for anyone who wants to start swimming in cold water and keep going through the winter.

Questions

How do the downloads arrive?

After checkout you receive an email with a download link, and the same link is shown on the confirmation page. The journal and guides are PDFs made to print on ordinary A4 or Letter paper.

Is cold water swimming safe?

It can be, with care. Never swim alone, get in slowly, keep the first swims short and stay out when you feel numb. The safety cards cover this, but I am not a doctor, so talk to one if you have any health worries.

Do I need a wetsuit?

No. Most of what I wear is a hat, a pair of gloves and a robe for afterwards. The kit checklist shows what I add in each season.

Is there merch?

Yes: totes, tees, mugs and prints with my drawings of the seal and the wave and the rising sun. Each is printed to order and shipped by Printful, and the cost and delivery time show at checkout.

How often does the letter come, and how do I leave?

One every Sunday. Every email has an unsubscribe link at the bottom, and it works at once.
