Hydrographic and ADCP data were collected in the coastal waters of Oman during the 1987 summer monsoon. The minimum surface temperatures, up to 5°C below ambient offshore values, were found close to the coast and in the vicinity of the Kuria Muria Islands. Strong surface gradients were observed near Ras al Hadd at the entrance to the Gulf of Oman where the geostrophic surface flow exceeded 1.0 m/s. The alongshore flux in the top 300 m of a region extending 100 km from the coast was estimated to be 10 × 106 m3/s. Evidence for an offshore filament of cool water was found in both current and temperature data.
