Abstract	At selected sites around Southern Africa, Underwater Temperature Recorders (UTRs) have been used to obtain long-term records of bottom temperature in the nearshore environment, at depths ranging from 2m to 34m. Here we present processed hourly subsurface temperatures from UTRs located at a depth of 18m off Karange Island North (05.1560°S 39.1672°E), along the east coast of Southern Africa, between 11 October 2007 and 27 February 2013. Note that for some deployments, two UTRs were deployed to simultaneously record bottom temperatures.
Methods	A subsurface-mounted, Underwater Temperature Recorder (UTR) was deployed at a depth of 18m off Karange Island North (05.1560°S; 39.1672°E), along the east coast of Southern Africa. The instrument(s) measured hourly temperature(s) readings between 11 October 2007 14h00 and 27 February 2013 14h00.
