Graphic plotting maximum daily sea ice extent in the Bering Sea by the date of occurrence each year 1979 to 2026, with the symbols for each year color-coded by decade. The 1991-2020 median maximum extent is shown as a dashed line.

Sea ice extent in the Bering Sea reached it's maximum extent on March 22 in NSIDC data, very close to the 1991-2020 median. The distribution of ice was anything but typical, with near record high extent on the Alaska side of the Bering Sea and very low on the Russian side. #akwx #Arctic #SeaIce

Left: Bering Sea daily sea ice extent with the past two seasons and the smoothed 1991-2020 median highlighted. Also highlighted is the 2011-12 season, which had the highest sea ice extent in the satellite era.

Sea ice extent in the Bering Sea has very likely reached its maximum for the season in NSIDC data. Current extent is the highest for Mar 28 since 2013. Unlike the record spring of 2012, extent is much above normal in the eastern Bering Sea but below normal on the Russian side. #akwx #Arctic #SeaIce

More bad news for climate monitoring. Much like the fiasco with satellite derived sea ice info last summer, the very short notice of termination of a product that’s been available for decades has real world consequences. #Arctic #SeaIce

Arctic sea ice hits lowest winter level as unprecedented heat smashes records all over Earth The sea ice is crucial to Earth’s climate because without it reflecting sunlight, more heat energy goes into the oceans. Ice of all kinds around the poles acts as Earth’s refrigerator.

Arctic Sea Ice Maximum Extent 2026

• Arctic sea ice maximum extent for 2026, at 14.29 million km² (5.52 million mi²) March 15.
• Tying 2025 for lowest maximum in 48-year satellite record.

2025 minimum – 2026 maximum.

‘Very alarming’ winter sees Arctic sea ice hit record-low for second year running - Carbon Brief Arctic sea ice has reached its peak extent for this winter, clocking in as the joint-smallest in a satellite record going back almost half a century.

Map centered on western Alaska showing the satellite derived sea ice thickiness (meters) for the week of March 15-21, 2026. Ice thickness ranges from less than 0.3 meters in the open ocean in southeast Bering Sea to over two meters some areas in the Chukchi and Beaufort Seas.

Satellite-derived sea ice thickness around Alaska for the week ending March 26 courtesy AWI. Ice is thicker than 2011-25 median along the Alaska Chukchi coast and in the southeast Bering Sea, where the 15-year median extent is zero. Ice in the northern Bering Sea rather thin. #akwx #Arctic #SeaIce

Splash screen for the post: Alaska-style March Madness: Unusually cold and regionally snowy.

Most of Alaska has been atypically cold so far this month, and in Southeast it’s been snowy. But the big story: rarely seen high sea ice extent in the southeast Bering Sea. Details in the Alaska and Arctic Climate newsletter. #akwx #Arctic #Climate #SeaIce

Here's a quantitive answer. Sea ice thickness for the week of March 14-20, 2026. #SeaIce #akwx #Arctic

NOAA-21 Truecolor image centered on the eastern Bering Sea taken March 21, 2026 at 352pm AKDT. The sea ice edge is well defined and is clearly visible running from west of Cold Bay to southwest of St. Paul to well west of St. Matthew Island. Clouds obscure the ice edge near the Russian coast.

True color satellite image Saturday afternoon courtesy @alaskagina.bsky.social. Clear skies over most of the ice covered eastern Bering Sea. Might want to save this pix for future reference: sea ice in the eastern Bering this extensive only a couple of springs since 1970. #akwx #Arctic #SeaIce

Left: Bering Sea daily sea ice extent 1978-79 to 2025-26 with the past two seasons and the smoothed 1991-2020 median highlighted. Right: National Weather Service Alaska Sea Ice Program sea ice concentration analysis to March 21, 2026.

Sea ice extent in the Bering Sea well above average but not in the top ten for the date in NSIDC data. That's because there's little ice southwest of Cape Navarin. Ice in the southeast Bering Sea extent extends to Unimak Island, similar to the extreme springs of 2012 and 1976. #akwx #Arctic #SeaIce

NWS Alaska Sea Ice Program analysis of sea ice concentration for March 20, 2026 with several locations annotated on the graphic.

Sea ice extent in the southeast Bering Sea is near historic high levels. NWS Alaska Sea Ice Program analysis shows high concentration ice to the northeast shore of Unimak Island, west of Cold Bay. Since 1970, only 2012 and 1976 were close to having ice so far southwest. #akwx #weather #SeaIce

Sea ice extent in the Arctic has reached the maximum for 2026, and is effectively the same as last year's record low annual maximum in the satellite era (since 1979). Details in the latest from the Alaska and Arctic Climate newsletter. #akwx #Arctic #SeaIce
