Abstract	Here we present a collection of raw and processed temperatures from Underwater Temperature Recorders (UTRs) located off Ystervarkpunt, 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(s) (UTR) were deployed off Ystervarkpunt (34.395°S; 21.7305°E), along the south coast of South Africa. The instrument(s) measured hourly temperature(s) readings.
