FINA Requirements for Swimwear Approval (FRSA)

KCASA Open Water Championships 29th June 2019: 

The lowest temperature recorded during the competition at Surrey Quays in recent years was 19.5 degrees in July 2016. In previous years, it has been 20 to 23 degrees.  It is therefore anticipated that the competition will most likely be ‘non-wetsuit’.   Should the wearing of wetsuits be optional on the day there will be no separate classes for wetsuit and non-wetsuit swimmers.

Swim South East Open Water Championships 13th July 2019:

The water temperature at Chichester has consistently been in excess of 20 degrees in previous years and it is not anticipated that it will fall below 18 degrees, the point at which wetsuits become mandatory. Should the wearing of wetsuits be optional on the day there will be no separate classes for wetsuit and non-wetsuit swimmers.
