Guinea Current ( 
During the northern summer the Guinea Current begins at about 
1)°w as the eastern extension of the well-established Atlantic 
Equatorial Countercurrent. Table 10 shows the constancy of the pre- 
vailing current within the boundaries shown in Figure l.

Almost 1,500 observations show the prevailing direction to be east and 
the mean speed 1.2 knots; the table also indicates the general flow to 
be between northeast through southeast over 75 percent of the time, 
with a maximum speed of about 4.0 knots. 
The Guinea Current appears constant in direction except during 
December through February, when easterly winds reduce the speed and 
cause the current to become variable and at times to reverse; when 
reversed, the flow seldom exceeds 1 knot. During the northern winter 
(January through March) the Atlantic Equatorial Countercurrent is not 
well established or disappears, and the Guinea Current, mainly
