Synopsis – Low pressure will generally remain over the Bering Strait region through Monday, with high pressure over the eastern Beaufort Sea during that time.

Near St. Lawrence Island

There is shorefast ice along the north side of St. Lawrence Island extending 1 to 5 miles offshore. Beyond the shorefast ice on the north side of the island is compact pack ice consisting of medium to vast floes extending up to 18 miles beyond the shorefast ice. The nearest sea ice to Gambell is approximately 20 miles to the west and is close pack ice consisting of mainly brash ice. South of the island is open water. To the east of the island is open pack ice to close pack ice consisting of small to big floes up to 8 miles east of the island.


The nearest sea ice is 25 miles south of Nome, and is close pack ice consisting of brash ice to medium floes. The remainder of the area is sea ice free.

Brevig Mission/Port Clarence Area

The only sea ice remaining in this area is between Port Clarence and Teller. It is compact pack ice consisting of vast to giant floes.

Wales to Shishmaref

Previously shorefast ice extends up to 2.5 miles from the coast. This ice is showing signs of melting in place, so it is now considered compact pack ice although much of it is likely still fast to the shore/ocean floor. Beyond the shorefast ice is consolidated to compact ice consisting of medium to giant floes extending 5 to 20 miles north from Wales to Shishmaref, and 20 to 45 miles north from Shishmaref to Espenberg, then open pack ice to open water beyond that. To the west and northwest of Wales is generally open water.


The waters around Diomede are sea ice free. The nearest sea ice is near Wales, and is compact pack ice consisting of medium to giant floes.

Forecast Discussion

Ice Forecast

Sea ice will generally move with ocean currents through Sunday, then begin to drift northward as the southerly winds move in. Overall, sea ice in the Bering Strait region is melting quickly and the melting will be more significant than any amount of drifting in the next week.

Wind Synopsis

Winds will be mainly variable 5 to 10 kts (6 to 12 mph) from Friday, June 4th to Saturday, June 5th. Winds will shift to the north-northwest 5 to 15 kts (6 to 17 mph) Saturday night and continue into Sunday evening June 6th, with the strongest winds through the Bering Strait near Diomede. On Monday, June 7th, winds will shift to the south-southwest 10 to 20 kt (12 to 23 mph) across the region and persist through Friday, June 11th. The strongest winds will occur from the Bering Strait to St. Lawrence Island with the lighter winds near Nome and Shishmaref.

Temperature Trend

From Friday, June 4th through Sunday, June 6th, high temperatures will be in the upper 30's to upper 40's and overnight lows in the upper 20's to mid 30's, with the warmest readings near Nome.

Observations and Comments

Observations of Sea Ice Development

Observations from Savoonga

Thursday, 3 June 2021 – Aqef Waghiyi

Nobody went boating since the last time we talked. Still iced in. Not much really going on the past week. I was hoping for south winds. Next good boating weather gonna go chase the ice to the east side. Maybe I’m going to put my walrus stuff away and pull out seal, birds, and fishing gear. Nobody went boating practically the whole month of May.

The weather hasn't been good for boating and today the weather finally dying down also what ice we did have went south or south west with the north storm we just had.

Observations from Shishmaref

Friday, 4 June 2021 – Curtis Nayokpuk

Inch of fresh new snow on the ground this AM. Only a hand full of Bearded Seals brought in so far by hunters on snow mobiles. Off shore wind (east at 12) combined with new snow cover over thin ice will have hunters preparing boats and gear for hopefully launching along shore fast ice open leads when conditions permit.

The ice is getting smaller, no boats went out this week again cause of the hi wind.

Observations from Port Clarence and Brevig Mission

Friday, 4 June 2021 – Marcus Barr

After a long 2wks of strong northerly winds, SW wind came and pushed the ice in our bay up in front of Brevig. Still no boats had got out for seal or walrus.
