Beach House Beach is a saltwater beach in Kauai County, Hawaii. Across 23 bacteria samples collected between 2021 and 2023 at nearby monitoring stations, it earns a Beach Safety Grade of D — Poor.
About 13% of samples at Beach House Beach exceeded the EPA Beach Action Value of 104 CFU/100 mL for Enterococcus — the threshold at which water managers typically post a swimming advisory. In practice that means the safe-swimming limit was frequently crossed here over the monitored period. Bacteria samples frequently exceed the safe-swimming threshold; swimming advisories are common here.
Read this grade as directional rather than settled: it rests on only 23 samples and has no results reported since 2023. That is enough to classify how the water has behaved, but not enough to separate this beach from another a grade away — a beach graded from thousands of samples at several stations is a firmer read. As more results are reported, the grade may shift.
Beach House Beach was not under a swimming advisory in the most recent EPA snapshot. Conditions can change quickly after heavy rain or high runoff, so it's still worth checking the current advisory the day you go.
