We recently released our High School on SI Power 25 national high school football rankings.

Now, we break it down by region.

There’s a new No. 1 at the national and region level after Mater Dei cleaned its slate during its first season with multiple losses since 2015 by defeating St. John Bosco 36-31. The loss propelled Sierra Canyon, which remained undefeated, to the top spot going into the CIF Southern Section playoffs.

Meanwhile, No. 10 Kahuku in Hawaii reached the Oahu Open Division final by defeating Campbell 24-6. The  Red Raiders will vie for their second straight OIA title and fifth in six seasons this week against Kapolei, which upset Mililani 21-14 to earn a shot at its first OIA championship.

Here’s a look at our Top 10 teams in the Southwest Region (Arizona, California, Hawaii, Nevada, New Mexico).
