Ocean currents have a big role in the marine world. Conventional techniques of measuring ocean currents have spatial and time limitations. High Frequency Radar technology can overcome these obstacles as an alternative to solving solutions effectively and efficiently. The hydrodynamic model is used to predict sea surface currents, such as in Indonesia, known as Ina flows from BMKG and Ina OFS from Pusriskel. The aim of this study is to find out the accuracy of the Ina flows and Ina OFS hydrodynamic models in predicting sea surface currents against high frequency radar observations in Labuan Bajo Waters. The data used are output from Ina flows, Ina OFS and HF Radar in Labuan Bajo in February 2019. The method used to determine accuracy is by correlation coefficient, Root Mean Square Error, and eyeball method for spatial correlation. In general, the results of these tests indicate that Ina-flows has a higher value of accuracy and correlation in two points of the waters of Labuan Bajo with a value of around 0.5 to 0.6, while the error of sea surface currents direction is around 30 degrees to 60 degrees.
