@fosojedi said in Incorrect Wave direction in Route Planner:
Based on other information, the model detail is accurate per the model, while the route planner is not. Route planner seems to be showing completely different wave directions.
Where have your seen that Route planner is not accurate ?
Your issue about Waves direction is probably due to a wrong reference direction for wind and waves. See More option and set the reference direction (wind barbs) to North up.
