The ice covered an estimated 1.78 million square miles (4.6 million square kilometers), tying 2008, 2010, and 2025 for the 10th-lowest minimum in the satellite record. The last 20 years, 2007 through 2026, hold the 20 lowest minima.

NASA reported on Sept. 23, 2026, that Arctic sea ice reached its annual minimum on Sept. 12.

The ice covered an estimated 1.78 million square miles, or 4.6 million square kilometers.

That extent ties 2008, 2010, and 2025 for the 10th-lowest minimum in the satellite record, which begins in the late 1970s.

The last 20 years, 2007 through 2026, hold the 20 lowest minima.

The same report says Antarctic ice is nearing its annual maximum after an unusual mid-season dip. The Antarctic 2026 maximum is still pending.
