One of the gifts of Christmas 2013 to ourselves was a weather station. It has a rain gauge, determines wind speed, temperature and humidity inside and out, moon phase, date, time, and more. So when I say the wind is gusting at 20 to 30 mph, you will know that I am not guessing. There is a computer screen mounted in the kitchen and the information beamed in--no wires needed.
This is a close-up of the spinners that measure wind speed and direction.
