 Comparing February months

Climate February 2008

This was by far the coldest of the last nine Februaries, by day and by night. The mean daily maximum of 28.8°, the mean daily mean of 22.2°, and the mean daily minimum of 15.6° were all well below average, by 3.7°, 3.1°, and 2.5° respectively.
The contrast with the last two years is stark: the days in February 2007 were 4.5° hotter, and those in February 2006, 5.2° hotter than this month. (Note added: This cooling was global.)
With 58% of mornings exceeding 4 octas of cloud, this February, along with December 2007 (58%) and June 2007 (60%) was one of the cloudiest months in nine years. Most months in Manilla have about 30% cloudy mornings.

This month’s rainfall of 116 mm is in the 81st percentile of February totals. (Last February’s 128 mm was the seventeenth wettest February on record.) Taking rainfall totals for more than one month, every total up to 12 months is very high: above the 70th percentile.
