Wind Rose by hour

Remember my wind rose for my personal weather station? Well, I took a look at the wind rose for the station at the mouth of Spanish Fork Canyon and made a comparison.

This is ten minute wind data from January 1, 2014 thru March 24, 2015.


There strongest winds occur most frequently in the early morning hours, between midnight through 9:00 AM. Then the winds begin to weaken after 9:00 AM and remain weak throughout the daytime hours until 9:00 PM when the winds begin to strengthen again.

Compare this with my personal weather station. Notice the change in color scale which reveals that the winds at the canyon mouth are stronger than at my house. Still, the transition times between weak and strong winds at 10:00 AM and 5:00 PM exist.
