Mount Waiʻaleʻale (why ah lay ah lay), often spelled Waialeale in English without the ʻokina, is a shield volcano and the second highest point on the island of Kauaʻi in the Hawaiian Islands. Its name literally means "rippling water" or "overflowing water"
The mountain, at an elevation of 5,148 feet (1,569 m), averages more than 452 inches (11,500 mm) of rain a year since 1912, with a record 683 inches (17,300 mm) in 1982; its summit is one of the rainiest spots on earth. Recent reports though mention that over the period 1978–2007 the wettest spot in Hawaii is Big Bog on Maui (404 inches or 10,300 mm per year).
The summit of Waiʻaleʻale features a tropical rainforest climate (Köppen Af), with substantial rainfall throughout the course of the year. (Bodin 1978: 272) quotes 460.0 inches (11,684 mm) per year figure as being the 1912–45 average, an average that quite possibly will have changed since then, while The National Climatic Data Center quotes this figure as a 30-year average. The Weather Network and The Guinness Book of Weather Records (Holford 1977: 240) quotes 451.0 inches (11,455 mm) rain per year, while (Ahrens 2000: 528) quotes 460 inches (11,680 mm) as the average annual rainfall at Mount Waialeale and (Kroll 1995: 188) claims 510 inches (13,000 mm) falls here. Similarly, The Weather Network and the Guinness Book of Weather Records quote 335 days with rain here while (Simons 1996: 303) suggests that rain falls on 360 days per year.
The local tourist industry of Waialeale has promoted it as the wettest spot, although the 38-year average at Mawsynram, Meghalaya, India is higher at 467.4 inches (11,870 mm). Both Mawsynram and Cherrapunji in Meghalaya are recognized by the Guinness Book of World Records as having higher average rainfall. Mawsynram's rainfall is concentrated in the monsoon season, while the rain at Waiʻaleʻale is more evenly distributed through the year.
