Why Are Hurricanes Rare in Hawaii?
One would think that a group of tropical islands that lie just south of the Tropic of Cancer would be a prime target for hurricanes. Hawaii has plenty of heat, moisture, and waterfront, yet few hurricanes make landfall (which occurs when a hurricane’s eyewall crosses a coastline). Why have these islands been so lucky? Much of Hawaii’s good fortune has to do with being a small target in a large ocean, along with long-standing patterns of atmospheric and ocean circulation in the North Pacific, which protect the archipelago and dampen the effects of approaching storms (see also atmospheric circulation).
Hawaii’s 130-odd islands cover about one-fiftieth of 1 percent of the North Pacific Ocean. It’s a tiny area for any storm to hit, let alone a hurricane. (Most of Hawaii’s rain and snow is orographic precipitation, which is caused by winds forcing warm, moist air upslope to produce clouds and rain.) Still, Hawaii’s most important guardian against hurricanes is the North Pacific (or Hawaiian) high—a semipermanent subtropical high-pressure cell that sits northeast of the islands. Under the influence of high pressure, cooler, drier air aloft descends and spreads outward clockwise in all directions, creating an obstacle for storms (which are generated by low-pressure conditions that stem from rising warm, moist surface air) while also creating wind shear conditions that can stunt hurricane development.
Hurricanes also rely on large areas of warm ocean water (that is, those with temperatures of 26.5 °C [about 80 °F] or above) to fuel a cycle of evaporation, condensation, and convection that increases their intensity. Hurricanes that pass over patches of cooler water, however, are sapped of their energy and diminish. Since the North Pacific high also drives cooler water southward toward the islands—thermal imagery has shown that cool water is found primarily around the northern and eastern coasts of the larger islands and often wraps around to their southern coasts—approaching hurricanes and tropical storms must overcome both wind and water barriers to strike land.

This is not to say that Hawaii isn’t affected by hurricanes. Hurricanes Dot (1959) and Iniki (1992) made landfall on the island of Kauai, and there have been a number of near misses that have subjected the islands to tropical cyclone conditions. The most recent took place in August 2026, when Hurricane Lala passed within 48 km (30 miles) of the southern coast of the Big Island (Hawaii), its outer and middle bands dropping more than 50 cm (20 inches) of rain on the island. The Maui wildfires of 2023 were worsened by Hurricane Dora, which passed some 1,100 km (about 700 miles) south of the island chain; the difference in pressure between the hurricane’s low-pressure center to the south of the islands and the high pressure to the north generated 107-km-per-hour (67-mile-per-hour) winds that drove wildfires downslope into the coastal town of Lahaina.
