# MareSpot (marespot.com) > Smart guide to Croatian beaches, coves, sea water quality, and natural wind shelter for 1,031 officially monitored swimming locations across the Adriatic Sea. ## Overview MareSpot (https://marespot.com) is an open nautical, oceanographic, and coastal guide for Croatia. It computes natural wind shelter for every bay using geomorphological shoreline aspect angles combined in real time with official meteorological and oceanographic data (IZOR, DHMZ, Open-Meteo Marine). It answers the vital summer question for boaters, campers, families, and beachgoers: *"Where is the sea calm today, and which coves are sheltered from Bora or Jugo?"* ## Data Sources & Scientific Models 1. **IZOR Official Sea Quality**: Bi-weekly microbiological water sampling by the Institute of Oceanography and Fisheries under EU Bathing Water Directive 2006/7/EC and Regulation NN 73/08 standards. Classified into 4 grades: Excellent (blue), Good (green), Sufficient (yellow), and Poor (red), plus 15-parameter field terrain profiles (surface, seabed slope, pine shade, parking, dimensions). 2. **DHMZ Live Seawater & Weather Feed**: Real-time seawater temperature and coastal weather measurements from the Croatian Meteorological and Hydrological Service (DHMZ) across the Adriatic coast and islands (Rovinj, Pula, Crikvenica, Krk, Mali Lošinj, Rab, Zadar, Božava, Šibenik, Split, Hvar, Komiža, Makarska, Ploče, Mljet, Dubrovnik, and 60+ coastal stations). 3. **Open-Meteo Marine & MET Norway (api.met.no) Models**: Real-time and multi-day hourly wave height, wave period, wave direction, wind speed, gusts, sea surface temperature, and UV index. 4. **Geomorphological Shelter Calculator (GADM Vector Coastline)**: High-resolution calculation of coastal exposure bearing (0° to 360°) evaluating natural cove protection against dominant Adriatic winds: Bora/Bura (NE, 45°), Sirocco/Jugo (SE, 135°), Maestral (NW, 315°), Tramontana (N, 0°), and Libeccio/Lebić (SW, 225°). ## Information Architecture & URL Hierarchy The platform is organized in a 5-level geographic silo with full tri-lingual localization (Croatian `hr`, English `en`, German `de`) and interactive OpenStreetMap + ESRI Satellite (Orthophoto) maps on every page: -
