Peskio is a fishing-planning service that helps anglers decide when and where to fish by providing daily forecasts for coastal and river locations. Visitors can explore nearby spots or browse fishing places by country, with listings across destinations including the United States, Norway, Spain, France, and Italy. Each location receives a daily score from 0 to 100, along with a straightforward go, marginal, or no-call recommendation. Place pages explain the score and identify the best hours for fishing.

Peskio’s predictions combine several factors: tide movement, which can influence fish feeding; major and minor solunar periods based on the moon’s position and phase; low-light periods around dawn and dusk; and, where forecasts are available, wind, waves, and pressure trends. The service is available in multiple languages, including English, Spanish, French, Italian, and Portuguese. Peskio states that its predictions are intended for sport fishing and are not valid for navigation. Its place, mapping, and water-clarity information draws on cited geographic, open-map, and Copernicus Marine data.
