 Comparing May monthsClimate May 2013.

The mean maximum temperature was half a degree high and the mean minimum half a degree low. The mean early morning dew point (2.6°) showed low humidity, but it was not as low as the May record of 0.8° set last year. There were far more cloudy mornings (42%) than usual (24%), but fewer than in 2010 or 2011 (48%). The subsoil was 2.4° warmer than normal: its autumn cooling remained three weeks late.

The rainfall total of 13.6 mm was far below the average of 40.3 mm, but May has less rain than that in 23% of the years. Furthermore, Manilla’s May rainfall has been low for many years: in this century, only May 2011 (43.2 mm) beat the long-term average.
The two month total of 18 mm is now a severe shortage: in the 3rd percentile.
