Comparing MX WLL wind speeds with weatherlink.com
Posted: Fri 05 May 2023 4:46 pm
Just so you are aware, [by default] CMX will always show a 10-minute gust and average wind speed for your WLL.
WeatherLink .com on the other hand...
For the historic data the gust and average speed is the maximum gust and the average over the archive interval. So that could be anywhere from 1 to 60 minutes.
For the Bulletin page, the average speed is a 1 minute average - I do not know for sure but I'm assuming the gust is the same.
So direct comparison of the values between CMX (or any other software) and wl.com is nigh on impossible. And for me with 5 minute logging on wl.com this makes the wind data there pretty useless, you can get the max gust value, but average speeds are meaningless.
