Please note that there were significant changes to the weather station from 28 - 30 July 2019. Windchill was only recorded from these dates, and the wind sensors were recalibrated and checked. This showed that previous windspeed and gust readings were significantly low. The previous readings have not been adjusted. Obviously, this means that wind data before 1 August 2019 is not accurate (though it was consistent with itself) and should not be compared with data after then. Pressure, temperature (including heat index), dew point, precipitation, humidity data, and wind direction were similarly (and reasonably accurately) recorded from 1 February 2018 when the weather station was first in operation and may be validly compared from year to year.
