Unalaska Bay is a spot in the main bay of Unalaska in the Aleutian Islands. The bay offers slightly more protection than nearby Dutch Harbor, but conditions remain extreme. Dominant winds come from the SE and NW/NNW, often with considerable force. Unalaska Island is volcanic (Makushin Volcano, 1,800 m/5,900 ft) and katabatic winds (williwaws) descending from the volcano can be devastating. The spot is reserved for expert riders accustomed to extreme conditions. Even in summer, storms are frequent.

GLACIAL water year-round (3-10°C/37-50°F in summer) — dry suit MANDATORY. The bottom is a mix of volcanic rocks, black sand, and kelp. Moderate tidal range. Tidal currents in the bay. Water is often very rough even inside the bay. North Pacific swells penetrate the bay. Kelp forests can interfere with sailing.
Williwaws (katabatic winds) descending from Makushin Volcano — violent, unpredictable gusts exceeding 80 knots. Extreme weather conditions — "the birthplace of storms." Deadly glacial water. Commercial fishing traffic. Volcanic rocks and reefs. Kelp forests. Near-permanent fog. Extreme remoteness. Strong currents. Marine wildlife: sea otters, seals, Steller sea lions (threatened species), orcas. Potential volcanic activity (Makushin is an active volcano).
