The API that answers: "should I go to the beach today?"

One REST API call returns real-time water quality grades, wave height, water temperature, UV index, wind speed, tide data, and active advisories — covering 500+ beaches across the United States and Australia.

The problem

Coastal data in the US is fragmented across NOAA buoys, state water quality programs, tide stations, and county health advisories — each with different APIs, formats, and auth schemes. Anyone building a travel app, real estate tool, outdoor recreation product, or local weather service has to scrape and stitch together multiple sources.

Beach Day API solves this by aggregating all of it into one clean REST API. One curl call, one JSON response, one answer.
