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 been adjusted to match and so reasonably accurate comparisons can be made since 1 March 2018 to now.
