Do you have a question
about London City Swim?

What time does the swim start?

The first wave will take place at 4pm, we encourage you to get to the venue for 3pm at the latest to familiarise yourself with the venue, registration and to get your wetsuit and swimmers pack in time for your wave.

How warm will the water be?

We expect the water to be between 17 and 20 degrees C at the end of September, perfect for a swim!

Do I have to wear a wetsuit?

Wetsuits are not compulsory. The water isn September will probably be around 15 degrees,. If you are not acclimatised to swimming in cold water without a wetsuit, we recommend that you wear one.

If you wish to hire a wetsuit, we have an arrangement with a wetsuit supplier who will be supplying Orca open water suits, at a reduced rate of £10 /wk, £5 on the day rate (booked in advance).

Where can I find detailed info about the London City Swim?

The Swimmers’ Information Pack will be available to download closer to the event. We have also aimed to give as much information throughout this site.

I don't have a towfloat, does this matter?

All swimmers will be required to use a towfloat. Our partners Swim Secure are supplying towfloats for use on the day. These will be supplied to all swimmers, and must be returned after use.
