Leaderboard + badges + dive shop backlinks. - Photo feed: https://www.freedivingkohsamui.com/conditions/gallery ### Scoring methodology (0-100) - Wind (30 pts, with per-site directional exposure) - Wave height (20 pts) - Swell (10 pts) - Ocean current velocity (20 pts) - Visibility proxy: 60% 7-day rainfall + 40% Gulf seasonal plankton bloom (15 pts) - Spring-tide penalty for shallow coastal sites ≤20m depth (−0 to −5 pts) - Forecast ensemble-averaged across ECMWF best_match and GFS global. ### Data sources - Open-Meteo Marine API (waves, swell, ocean current, sea surface temperature) - Open-Meteo ECMWF + GFS weather forecast (wind, gusts, direction, rainfall) - Instructor ground-truth reports (viz, current, thermocline) — calibrates seasonal models ### Accuracy notes The tracker is freediving-specific — unlike general marine forecasts it penalises ocean currents and plankton blooms that matter for visibility and safety, and gives sheltered sites credit when wind is from their protected quarter. Ground-truth instructor logs improve accuracy over time. Still experimental — the human crew on WhatsApp is always more accurate for same-day conditions. ## Contact - Website: https://www.freedivingkohsamui.com - WhatsApp: +66 65 557 1148 - Email: diego@breathflowconnection.com
