The weather station in use is the WMR 200, and these pages are updated every 5 minute. The meteorological day used at this station ends at midnight. The temperature and humidity sensor is housed in a radiation shield to avoid temperature errors as a result of direct sunlight and the rain gauge is modified so that rainfall can be measured to an accuracy of 0.1mm. Wind chill Temperature is only defined for temperatures at or below 10 C and wind speeds above 4.8 kilometres per hour. The weather station is managed by Herman van Niekerk.

Justice" from the Cumulus Forum.
