Rough surf along the coasts of Kauai combined with torrential rainfall to produce widespread coastal flooding. Waves at Port Allen peaked at 35 ft (10.7 m). Pineapple plantations were inundated, with losses exceeding US$200,000. Infrastructure damage as a result of wave action was spotty but nonetheless amounted to US$100,000. The August 1959 rainfall total in Lihue, largely attributed to Dot, measured , in excess of normal. The heavy rainfall caused rivers and streams to swell and inundate adjacent areas. Despite making landfall as a weak Category 1 hurricane, Dot brought damaging winds inland, with a maximum wind gust of 103 mph (166 km/h) reported at Kilauea Light. However, gusts as high as 125 mph (200 km/h) were estimated given the snapping of palm trees. Strong winds damaged hundreds of buildings in the areas of Kilauea, Lihue, and Lawai, Hawaii. Extensive losses resulted from the damaging and toppling of macadamia trees. However, of the crops on Kauai, cane suffered the greatest impact with damage figures reaching US$2.7 million. The toppling of power lines caused power outages across the island; fallen lines also blocked roads. Water supply to some communities failed due to the lack of electricity. With the exception of emergency radio transmitters, telecommunications on Kauai failed. The damage toll from Dot for the entirety of Hawaii totaled US$6 million, making the hurricane the costliest in Hawaiian history before it was surpassed by hurricanes Iwa, Iniki and Iselle in 1982, 1992 and 2014, respectively. Adjusted for inflation, Dot's damage figure nears US$50 million.
