Stoneleigh weather - since records began

Amateur weather station readings at Stoneleigh, near Epsom, UK (N51.36 W0.25). No accuracy is claimed for this data. Use at your own risk.

Data is logged and graphs are drawn by pywws software on a Raspberry Pi running Raspbian Linux.

Notes on the measurements

I bought my first weather station in May 2008, so that month's data is incomplete. During September 2008 the rain sensor stopped working. I mended it in late November, so three months' rain readings are too low.

The weather station's temperature sensor reads too high (because of inadequate shielding from sunlight). According to the UK Met. Office, mean daily maximum temperatures in the London area peak at 22.5°C in July. However, my minimum temperature readings seem to be about right.
