Technical Notes

Temperature charting commenced on 5^th May 2001; rainfall charting commenced on 18^th August 2002; charting of additional data commenced on 1^st January 2010.
The weather station sensors are located in an exposed position above the roof of my garage (right). Data from the in-house base unit are normally noted every morning, charted (using Microsoft Excel spreadsheet), and then uploaded onto the website.
