Map of location of Mt. Waialeale rain gage.Data collected after January 12, 2015 are provisional and have not been reviewed or edited. They may be subject to significant change.

The rain gage near the summit of Mt. Waialeale is at an altitude of 5,150 ft (gage photo). The gage has been in operation since 1910 but monthly totals are available only for 1950-54 and 1968 to the present. The data prior to 1993 are from unpublished monthly records. The average yearly rainfall at the gage during those years is about 383 inches and for the entire available period (1912-present) is about 422 inches. Rainfall for October 2015 (14.7 inches) can be compared with island-wide rainfall data recorded by the National Weather Service. This station is operated by the Honolulu field office with funding from the USGS National Streamflow Information Program and is equipped with a satellite transmitter delivering rainfall updates every hour (Go to real-time website for this gage.).
