Abstract	Here we present a collection of raw and processed temperatures from Underwater Temperature Recorders (UTRs) located off Knysna, South Africa. At selected sites around Southern Africa, UTRs have been used to obtain long-term records of bottom temperatures in the nearshore environment, at depths ranging from 2m to 34m.
Methods	Subsurface-mounted, Underwater Temperature Recorder (UTR) was deployed off Knysna (34.0763°S; 23.0602°E), along the south coast of Southern Africa. The instrument(s) measured hourly temperature(s) readings.
