My AWS is in a fairly sheltered position in the back garden due to

sunlight, so temperature and rainfall figures are pretty accurate.
However, experience has shown that wind speeds are consistently
under-read by about 50%, with anything above 30kph being somewhat news
worthy. It's just topped out at 56kph and 55kph in the last 20 minutes.

The speed dial (Cumulus) on the computer display usually covers 0-50kph.
It had to re-draw itself for a short while to cover 0-100kph!!!


I matched my 36mph record of 2 days previously, here. Surprised it
wasn't exceeded though, based on the noise!
