This chart shows the daily rainfall totals.
After a frosty night, the frost thawing can appear as trace 'rainfall'. When this occurs, the day's ranfall is set to zero in this chart and the day is not included in the 'rainy day' count.
This chart shows the rainfall rate and sun during the day.
Prolonged gentle drizzle may be clearly differentiated from short sharp showers.
After a frosty night a .3mm/hr blip may be seen as the frost thaws. This is suppressed in the rainfall totals chart above.
Snowfall will of course only be registered after a thaw, so there could be a significant delay between it falling and it being registered (e.g. the 9th January 2021). Snowfall and frost-melt are shown in grey; rainfall in blue.
In 2020, the sunshine was derived from the UV index adjusted according to sun elevation. Hover over the graph to see UV index.
Unfortunately the UV sensor does not record at all in the winter months. Instead, since the beginning of 2021, sunshine is determined from a jamjar with a temperature sensor inside, utilising the greenhouse effect. This works surprisingly well.

The wind direction on the x axis relates to the average wind vector. Hover over data point to see direction of maximum wind gust.
The diagram shows wind vectors, averaged every 30 minutes.
The red spots represent wind gusts, and the blue spots wind averages.
The further from the centre, the higher the wind speed.
