Welcome to the only personal weather station in Blairgowrie, a suburb of Randburg, situated just to the north of Johannesburg in the Gauteng Province of South Africa where the time now is 11:52:01 and it currently is 22.4 °C outside and the temperature is Rising. This time yesterday it was 20.7 °C outside. But, because of the relative humidity being 36% and a current windspeed of 2.9 km/h (Light air), gutsing at 8.6 km/h from the NW it now feels like 21.0 °C outside. We experienced a low of 10.7 °C and a high of 22.6 °C so far for today compared to 8.8 °C and 22.0 °C measured for yesterday. The lowest and higest temperatures recorded for this year by this station was 8.8 °C on 18 April and 35.7 °C on 18 January respectively. At the moment the barometric pressure is Steady and the average wind direction the last 10 minutes was from the NW with the predominant wind direction for today being from the NNW with a windrun of 11.7 kilometers up to now compared to NW and 42.9 kilometers for yesterday. The higest average wind speed for today was 7.4 km/h (Light breeze) at 11:31 with a gust of 13.7 km/h at 11:24 compared to 9.4 km/h (Light breeze) at 11:29 with a gust of 15.8 km/h at 11:20 yesterday. Here, in a summer monsoon type of climate (the longest period this year without any rain was 11 days ending on 13 April), it last rained 2 days ago on 2014-04-16 19:14 and we received 351.5 mm of rainfall this year. This is a weather station that reports current weather conditions and provide a record of past weather related information. No real attempt is made to forecast weather, but a good indication of the weather conditions for the next day are provided by the "Zambretti Forecast Model".

The weather station in use is the WMR 200, and these pages are updated every 1 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 Dr Herman van Niekerk (PhD Geology).

Justice" from the Cumulus Forum.
