Afaik there arecurrently zero courses with the necessary FIA grading of Grade 1 in Africa. Morocco has multiple Grade 2 circuits, and Kyalami used to be Grade 2 but that expired a year ago, so they are currently ungraded.

That means that in order to be eligible for an F1 race, these courses would need to modernize and undergo an FIA process.

I personally assume that due to this, any African race we could get would be a street track.
