How does the temperature of surface waters in the Atlantic Ocean change in latitude? Why do you think?

The average annual temperature of the surface waters of the Atlantic Ocean is 16.9 * C. Its annual amplitude in equatorial-tropical latitudes is no more than 1-3 * C, in subtropical and temperate latitudes – 5-8 * C, polar – about 4 * C in the north and up to 1 * C in the south. In general, the temperature of the surface waters of the Atlantic decreases from the equator to high latitudes. In winter, in February in the Northern Hemisphere and in August in the Southern Hemisphere: it changes from +28 * C at the equator to +6 * C at 60 * N. and -1 * C at 60 * S, in summer, in August in the Northern Hemisphere and in February in the Southern: from +26 * C at the equator to +10 * C at 60 * N. and about 0 * C at 60 * S latitude. Ocean currents cause significant surface water temperature anomalies. The closer to the equator, the more the sun warms up the water.
