Trade Winds Weaken as Tropical System Lingers West of Hawaii
Trade Winds Weaken as Tropical System Lingers West of Hawaii
US · Published Aug 4, 2026
Trade winds across Hawaii are easing due to the presence of a tropical system west of the islands.
This pattern is expected to persist through Thursday, with scattered showers favoring windward and mountain areas, particularly on Maui and the Big Island.

Impact & Risks

The weakening trade winds and tropical system may lead to increased humidity and scattered showers, particularly in windward and mountainous areas. Rough surf on east-facing shores early in the week could pose risks for swimmers and small watercraft. The arrival of a south swell on Saturday will bring modest wave growth, which may attract surfers but could also increase the risk of rip currents. Leeward areas are expected to remain mostly dry, minimizing risks in those regions.
