How's the beach today? Costa gives you an answer, not a table of numbers. A single number from 1 to 100, the Costa Score, sums up conditions at more than 110 beaches across Puerto Rico, in 37 municipalities and all six coasts. Underneath that number is everything that went into it: currents, surf, wind, water quality, clarity, sargassum, Saharan dust, UV index, water temperature, tide and weather. HOW IT WORKS Costa produces no data of its own. It reads 19 official sources (National Weather Service, NOAA, CARICOOS, Puerto Rico's Environmental Quality Board, the San Juan Bay Estuary Program, satellites from USF and NOAA CoastWatch, Copernicus CAMS) and turns them into something you can read at a glance. Readings are recalculated every 15 minutes. WHAT YOU GET • A clear verdict on whether the water is worth getting into, and why • Rip current advisories, bacteria levels and sargassum, stated plainly • Report sargassum from the beach, anonymous and in seconds • 17 balnearios (Puerto Rico's government-run public beaches) and 26 kid-friendly beaches, marked • Filters: Best right now, Favorites, No sargassum, Balnearios, For surfing • Map, photos and directions • In Spanish and English HONESTY FIRST When we don't know something, we say so. If there is no water sampling near a beach, Costa does not paint a reassuring green: it says there is no data. A forecast never disguises itself as an observation. Every reading shows its source and when it was taken. Costa is free, has no ads, and never asks you to create an account. Made in Puerto Rico. Costa is a guidance tool, not a lifesaving service. The ocean changes by the minute. Always follow the flags, the lifeguards and your own judgment.
