To avoid underestimating wind in coastal areas in GFS27, we adjusted the data interpolation to select the highest wind values around your spot. Wind speed is the only difference between GFS+ and GFS27.
Pros: On sunny beach days or in strong, gusty conditions, this can give a better idea of what to expect.
Cons: In areas without local wind effects, such as wind-sheltered locations, wind speed may appear overestimated.
