Although a great deal of work has been done on the prediction of the sunspot number 1–10 years in advance, very little has been done on the related problem of predicting the level of geomagnetic activity. It is sometimes assumed, apparently, that a prediction of sunspot number is a fairly good guide to the level of geomagnetic activity to be expected, but this is far from the case. However, long‐term prediction of geomagnetic activity is important both for space mission planning and to test our empirical understanding of the relationship of the solar wind to the solar cycle. In this review we bring together the work that has been done in this field to provide a ready reference both for the specialist in solar‐terrestrial relations and for others requiring geomagnetic prediction capability. We find, however, that surprisingly little attention has been paid to this problem, and it is our hope that this review will stimulate further work.
