Record #00512Nature archive
Mount Waiʻaleʻale on Kauaʻi, Hawaii, is reported by a record registry to have up to 350 rainy days per year. The reporting year and measurable-rain threshold are not specified, so the value is not a fixed annual average.
Current Record
up to350days/year
Current record value
Moist Pacific trade winds rise over Kauaʻi's interior mountains, cooling and producing frequent orographic precipitation. Local windward topography can yield far more wet days than nearby lowlands.
The metric is days with rain, not total annual rainfall or a single storm's intensity. Rain-day thresholds and station siting vary among climate datasets, and the published figure has not been reconstructed from an identified full-year daily station series.
Credible sources support core facts; the comparison scope or corroboration remains incomplete.
Basis: direct confirmation by an authority
Guinness lists Mount Waiʻaleʻale with up to 350 rainy days annually, but does not specify the observing year, station or measurable-precipitation threshold. The year-0001 metadata is an invalid placeholder. Developing status is retained.
Only the registry's up-to-350-day claim is directly confirmed; complete daily observations and a consistent rainfall-day threshold are not independently reproduced.
Current Entry identifies the current entry in this archive; it does not establish that the record is still held today.
The record value on this page is organized from the public sources above. Measurement methods may differ; JiLuDB follows the unified method described for each entry.
