April 6, 2026 — Scientists say sea ice in the Arctic hit its seasonal peak on March 15 – and it was the lowest peak on record. That probably comes as a surprise for fishermen who work the Bering Sea, where sea ice kept expanding for another week and hit its highest peak since 2013, extending south all the way to parts of the Aleutian Islands.
Sea ice last month completely froze over Bristol Bay and the north end of the Alaska Peninsula, past Nelson Lagoon. It reached Cold Bay, Unimak Island – even the Pribilof Islands.
“The Bering Sea is the only place in the Arctic where sea ice is above normal,” Rick Thoman said. “To our west, in the Sea of Okhotsk, so west of Kamchatka, it’s the lowest sea ice extent of record [as of March 19].”
Thoman, a climatologist with the Alaska Center for Climate Assessment and Preparedness, said there’s been a persistent series of high-pressure storms that have caused significant sea ice growth in the eastern Bering Sea by holding colder air in that area this winter. But that has also prevented sea ice from forming west of the International Date Line in Russian waters.
“That big high pressure over the Bering Sea has steered many storms and their south winds into the Sea of Okhotsk,” Thoman said. “They just have not been able to form much sea ice.”
