SIWO Forecast – April 3, 2026

Assessment of Current Ice Conditions Relevant to Distribution and Access of Walrus

Synopsis: Spring-like conditions are going to continue through much of next week. High pressure remains over eastern Siberia, which is allowing for the island to be dry. This high pressure will slowly move east by Wednesday (4/8) bringing increasing chances for precipitation Wednesday (4/8) and Thursday (4/9). Winds are anticipated to be light through the week. Temperatures will be in the 20s throughout the week with increasing temperatures with the precipitation chances 4/8–4/9.

Near St. Lawrence Island

Sea ice between Gambell and Savoonga is possibly shorefast, but the lack of recent southerly wind forcing makes it difficult to tell. There are two polynyas forming along the south side of the island, one southeast of Powooiliak (Pugughileq) Camp through Silook Camp, and another between Kialegak Point and Kilaknak Lagoon. Some old ice has come southward through the Bering Strait north of the island, but the majority of ice is first-year medium and first-year thin.

Forecast Discussion

Ice Forecast

Expect tides and local currents to be the predominant mover of sea ice for the next week. Seasonally, we are already seeing the effects of longer daylight hours. New ice is struggling to form, and areas of open water have been showing up with the warm currents northwest of St. Lawrence Island. On Wednesday (4/8) expect sea ice to move to the south 5–10 nm/day.

Wind Synopsis

St. Lawrence Island:

Thursday (4/2) through Monday (4/6) will see winds out of the northeast with winds steadily decreasing through this period. The strongest winds will be Thursday (4/2) and Friday (4/3) with wind gusts up to 25 knots, by Saturday (4/4) these wind gusts will have decreased to 10 knots. Monday (4/6) will see winds shift easterly with wind gusts of 10 to 15 knots. These easterly winds will continue through Wednesday (4/8). Wednesday night (4/8) and into Thursday (4/9) the winds will be variable as a surface low moves across the Island.

Temperature Trend

St. Lawrence Island:

Daytime temperatures will be in the 20s through much of the week. Wednesday (4/8) will see temperatures rise into the low 30s with the arrival of precipitation. Nighttime temperatures will remain in the 10s above 0 through the whole forecast period.

The images below show animations of the movement of ice predicted by the HYbrid Coordinate Ocean Model (HYCOM). Snapshots from the forecast show ice coverage from 0% (black) to 100% (white) and arrows show the relative speed and direction of the ice. A light boundary is drawn at 15% predicted ice cover to highlight the ice edge, but ice may be predicted to extend beyond it. Some bays, lagoons, and areas very close to shore are not covered by the model. (Image produced by the Alaska Ocean Observing System / Axiom Data Science).
