“Extreme cloudiness”

Most of the March 2011 raw data values (in orange) are nearer to normal than to recent extremes. As an exception, the March cloudiness anomaly is a record +37%: there were 19 cloudy mornings instead of 8.

Smoothed September values include new 12-year record anomalies for daily maximum temperature (low), cloudy days (high) and daily temperature range (low).

Note: Fully smoothed data – Gaussian smoothing with half-width 6 months – are plotted in red, partly smoothed data uncoloured, and raw data for the last data point in orange. January data points are marked by squares. Blue diamonds and the dashed blue rectangle show the extreme values in the fully smoothed data record since September 1999.
