Wessex O. C. is a relatively small club. Its members are mainly drawn from the Bournemouth, Poole and Christchurch conurbation extending into the New Forest and also into the more rural areas of Dorset. The Club is affiliated to the South West Orienteering Association (SWOA).
The club has a hardcore of members who attend most major events in the South as well as some of the multi-day events such as the J.K. Easter weekend and the Scottish Six Days. However there are also many members who orienteer less frequently, preferring to restrict their travelling to more local events.
