    wind variance

    I noticed today that there seems to be a variance between swellinfo wind predictions and the weather channel by about 10-15 mph. Anyone know why this is? Is it because swellinfo is just looking at wind speed on ocean/shore and weather channel for the region? note this is not a grip about swellinfo i'm just curious.

    Not positive but I heard once that the weather channel uses an average wind speed for the region. Regardless I've found better luck with magicseaweed's wind report.

    Swellinfo forecasts winds right offshore of the coast, the weather channel is likely to give you wind forecasts that are inland... There can be a big difference between winds right along the coast and winds that are inland.

    But, I will always look at the buoy/land station map, to see what the actual measurements are and how the forecasts are compared to the observations.
