Clark was offered the role at the beginning of March and has already taken charge of three games, including one in the CAF Champions League.
"I'm loving it. The thought of coming back [to the UK] hasn't crossed my mind. I'm loving this experience," he told the Daily Star.
"Al Ahly, a massive powerhouse of a club in Egypt, they get 80,000 every week at home. The crowds and the passion over here is amazing. The African nations are brilliant.
"I've read a report the UK is set for a heatwave of 24 or 25 degrees. If that was the temperature here, the players would be wearing overcoats. They were cold yesterday because of a little bit of wind and it was 33 [degrees]."
He added: "I've always had an ambition to work overseas, for a new experience, a new venture, a new culture," he continued.
"This offer came a couple of weeks ago. I looked into the club, saw it was in the top five clubs in Africa. When Covid-19 clears there'll be 43,000 fans here for the Champions League and anywhere between 25,000 to 43,000 in the league games. They're unbelievably supported.
"Competing in the African Champions League and the Arab Champions League is an opportunity to work at a higher level. I didn't know a lot about Sudan but I've met very good people who are very respectful and I'm really enjoying it."
