March 2022: The current rain gauge has now failed, joining the wind speed, wind direction & humidity sensors that had already failed.

Over the years all these sensors have failed & been replaced multiple times. My priorities have changed & I no longer intended to get replacements.

This site will remain here for the present, for historical data and the limited set of working sensors (temp, pressure, solar). At some point I'll probably take it down.

PS. Since I started collecting this data in 2008, the localised Met Office data & forecasts have improved greatly. Well worth a look (see side menu bar).
