Trends to June 2016.

June raw anomaly data (orange)

In June 2016, raw anomalies for all moisture variables became very high, while daily maximum temperature became very cool. Rainfall was more than 70 mm higher than normal (40 mm), and daily temperature range more than 4 degrees narrower than normal (15 degrees). Skies were cloudy and the dew point high. The two other temperature variables did not conform. Daily minimum temperature anomaly was very high, making the climate more coastal. Subsoil temperature anomaly was also high: the curve shows it trailing daily maximum temperature anomaly, after leading it for years.

 Fully smoothed data (red)

Fully-smoothed data are now available up to December 2015. In general, it was a time of normal climate. Anomalies were small and changing only slowly. Daily maximum temperature was rather high, and dew point rather low.


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.

Normal values are based on averages for the decade from March 1999.* They appear on these graphs as a turquoise (turquoise) circle at the origin (0,0). A range of anomalies called “normal” is shown by a dashed rectangle in aqua (aqua). For values in degrees, the assigned normal range is +/-0.7°; for cloudiness, +/-7%; for monthly rainfall, +/-14 mm.

 * Normal values for rainfall are based on averages for the 125 years beginning 1883.
