The invention discloses a method for data inversion of sea surface currents on basis of navigation buoys. The method comprises the following steps of: 1, setting a navigation buoy in an observation sea area and carrying a current data measurement system; 2, carrying out correction according to buoy position data collected by the current data measurement system to obtain a motion parameter of the buoy; 3, establishing a buoy stress model according to the buoy position data collected by the current data measurement system; 4, analyzing a current resistance parameter suffered by the buoy in the buoy stress model through a current inversion algorithm; 5, operating the motion parameter of the buoy in the step 2 and the current resistance parameter suffered by the buoy in the step 3 to obtain initial values for observing the current flow speed and direction of the sea area; and 6, correcting the current flow speed and direction obtained in the step 5 to obtain a final current flow speed value.
