As in summer 2008-09, day temperatures got steadily warmer. From 8° below normal in mid-December they rose to 5° above normal in early February, and crashed to below normal before recovering. As in 2008-09, the lower temperature in mid-February came with a day of very heavy rain.
As is normal, there were two days over 40° and none below 20°.
The mean daily mean temperature was normal but, due to cloud cover, the mean maximum was rather low (31.6°) and the mean minimum rather high(18.1°), reducing the mean daily temperature range to 13.6° (normally 15.1°).
This summer was the cloudiest in this record, at 54% cloudy mornings (more than four eighths of cloud), just beating the summer of 2007-08 (53%). Given that Manilla summers averaged only 31% cloudy mornings from 1999 to 2008, this is a big change indeed.
The total rainfall of 270 mm is above the long-term summer average of 225 mm. It is in the 68th percentile.
