Methodology: Statistics in this report come from our pipeline's aggregation of Hawaii DOH Clean Water Branch advisory data across 31 tracked beaches (last 14 days compared against the 14 days before). Forecast data from NOAA National Weather Service (api.weather.gov) sampled at each island's primary tourist coast. All numbers accurate as of publication. This report describes water-quality trends and forecast; it is not a swim recommendation. Physical hazards (shore break, rip currents, surf, marine life) are independent of water quality. Always check the individual beach page and local conditions before entering the water.
