You're probably comparing gusts and average speeds. If you have a Fine Offset station, see [[#What_do_the_various_wind_speeds_in_Cumulus_correspond_to.2C_with_Fine_Offset_stations.3F]]  
You're probably misunderstood Cumulus processing of wind speeds, looking at different parameters, or different averaging periods.
*If you have a Davis weather station see [[#What_do_the_various_wind_speeds_in_Cumulus_correspond_to.2C_with_Davis_stations.3F]]
*If you have a Fine Offset station, see [[#What_do_the_various_wind_speeds_in_Cumulus_correspond_to.2C_with_Fine_Offset_stations.3F]]
* For Oregon Scientific and La Crosse stations see [[#How_do_I_set_up_recording_wind_speeds_in_Cumulus.2C_with_Oregon_Scientific_and_La_Crosse_stations]]


Note that you can't compare the graphs drawn by Easyweather and Cumulus unless you are certain that they are plotting the same data. They can't both be running at the same time, so one would normally be plotting 'live' data at a given interval, and the other will be plotting data downloaded from the station's logger. The wind speed will hence not normally be the same for a particular time on the graph as it may well have changed at the point that it is saved to the logger. The only situation where it ''would'' be valid to compare the graphs would be if neither were running at the times you are comparing, and both subsequently downloaded the same data from the logger.
