Records began on 15 April 2009. Here are the extremes recorded since then.

These are the records for the manual data. See also the records here using the Cumulus weather station software which begun in October 2011 in addition to these manual recordings. This page is updated on a monthly basis with many readings from the manual records more accurate than the station in use with Cumulus as the manual data makes allowances for inaccurate data due to the siting of the sensors. This is because the overnight temperature and humidity are under the eaves and does not measure the full extremes, wind readings are not entirely accurate and the automatic rain gauge only measures to 0.5mm and is not as accurate as the manual gauge which measures to 0.1mm and also the lack of frequent sampling of the data particularly wind readings. However certain records calculated by Cumulus such as Wind Run, Rain Rate, Hourly rain, Heating Degree Days, Cooling Degree Days, Heat Index and so on were not recorded prior to October 2011.

Records began for barometric pressure from 15 April 2009 measured once each morning, from 16 May 2009 an afternoon reading was also measured followed by the addition of an evening reading on the 23 May 2009. From the 15 February 2010 daily minimum and maximum readings were made instead. Please note prior to October 06 2011 air pressure was only measured to the whole hpa before being measured to 0.1 hpa. Therefore the record for a daily range of 0 hpa is a result of that rounding. Temperature and humidity readings were made in a limited manner from 12 June 2009 until the 14 February 2010. From 15 February 2010 all readings were made with time of the occurrence of the extremes. Wind records with the time it occurred started from 15 February 2010. Rain readings are made using a manual rain gauge read on a daily basis and are adjusted to the 24 hrs. to 9am.

Up to date for data up to 31 December 2012.
