Comparing February months

Most of the last seven February months have been unusual in some way. This month was very dry, with near-record low rainfall and very low humidity. By contrast, February 2012 was very wet, as well as very cool. Both 2011 and 2014 were very warm, but 2011 was also very cloudy and humid. February 2013 was the coolest, without being wet like 2012.
The total rainfall of 7.6 mm this month was very low (6th percentile): this was the 8th driest February, and the driest since 1989, which (like 1974) had 7.0 mm. Still, taking rainfall totals for groups of months, only the 24-month total (985 mm) is a serious shortage, in the 9th percentile.

With the retirement of the Post-master, Phil Pinch, the future of rainfall observations at Manilla Post Office (055031), kept for 132 years since March 1883, is uncertain.

Only five days were warmer than average. The final five days and four nights were very cool, taking the weekly average (normally the hottest of the year) down to five degrees below normal. (This would be normal for the end of March, not January!) There were fifteen rain days, equalling the 125-year record number for January, set in 1941. Rain was spread evenly through the month, with the highest reading 29.2 mm on the 2nd.

Comparing January months

The mean daily maximum temperature (31.4°) was well below the average of 33.8°. Since nights, at 17.6°, were near normal, the daily temperature range was the record narrow value for January of 13.8°.
The dew point (humidity) returned to a normal value of 12.9°, after last January’s arid 6.9°. Subsoil temperature (25.3°) fell to normal after two January months above normal.
The total rainfall of 117.4 mm was in the 75th percentile, well above the average of 87 mm. This clears all shortages in rainfall totals for groups of months. The lowest percentile value remaining (15th) is for the 18 month total of 746 mm.
