MAE Wind Speed
February 27, 2025
MAE Wind Speed means Mean Absolute Error for a wind speed forecast: the average size of the difference between predicted and observed wind speed, usually expressed in knots. In marine forecasting it shows, over a set period or area, how far a model’s wind speed predictions were from real conditions, without positive and negative errors cancelling each other out.
For boaters, a lower MAE indicates more dependable wind strength guidance for reefing decisions, fuel planning, arrival timing and route selection. Comparing MAE alongside Wind Speed, Wind Observations and Forecast Accuracy helps crews judge whether forecast wind strength is reliable enough for a coastal hop, race start or offshore passage.
MAE is one way to compare a Forecast Model such as ECMWF, GFS or ICON, but it should not be used alone. Local effects, squalls, gusts and model resolution still matter. PredictWind users can view multiple models, high-resolution wind maps and routing outputs to make a more balanced decision.
