The IBIWAM wave model has been upgraded to an exceptional 2.5 km resolution, providing highly detailed wave predictions from the Canary Islands in the south to the coasts of Ireland in the north. This improvement enables greater accuracy in forecasting wave height, direction, and period — critical factors for both professional and recreational surfers. Whether seeking powerful barrels or long, smooth rides, these forecasts offer unparalleled insight into ocean conditions, ensuring better planning and safer experiences.
Greater Detail for Optimal Wave Selection
Powered by data from the European Centre for Medium-Range Weather Forecasts (ECMWF) and provided through Copernicus Marine Services, the refined model captures subtle yet essential differences between local wind-driven waves and long-traveling swell waves. This enhanced precision is particularly valuable at world-renowned big-wave locations such as Praia do Norte in Nazaré, Portugal (pictured above), where recent swells have produced some of the largest waves on record. Understanding the interaction between wind shifts and swell direction is essential for optimising performance.
Beyond Surfing: Supporting Maritime Safety and Efficiency
In addition to its impact on surfing, enhanced wave forecasts are indispensable for maritime logistics, coastal management, and environmental research. Accurate wave data aids in route planning, fuel efficiency management, and vessel safety, while also supporting studies on coastal erosion and marine operations. These improvements contribute to more secure navigation, efficient shipping, and a deeper understanding of ocean dynamics.
