Weather log February 2009

February days began hot (37.8°), and got hotter. The 9th reached 40.9°: that was 7.5° above normal, and the hottest day of the summer. At 20°, nights were unpleasantly warm, but it is normal for the first week of February to have the hottest nights of the year (18.4°).
The daily maximum on the 14th was an amazingly cool 17.8°, that is, 23.1° lower than five days before! The reading was 15.2° below normal. On that day, half of NSW, excluding only the borders on the east, south and west, had daily maximum temperatures more than 12° below normal.
A wet spell from the 11th to the 17th brought most of the month’s rain.At Manilla the highest reading was 51.2 mm on the 15th.
The month ended dry, with temperatures normal, except that nights became cool.

Climate February 2009

This month’s climate was normal, if rather wet. Other Februaries on the graph vary in every way:

February 2005 was sunny, dry, and not humid;
February 2006 was hot and humid;
February 2007 was very rainy;
February 2008 was very cloudy and very cold.
The rainfall total (94.5 mm) was in the 75th percentile for the month; well above the February average of 67 mm. This neatly makes up the January shortfall. Rainfall totals for groups of months remain very high. The 6 month total (525 mm) is in the 92nd percentile, and more than 200 mm above the median value. Totals are still above the median for all periods up to 72 months, with the exception of the 36-month total, and that has now risen to the 46th percentile.

Reading the 7-day mean temperatures, the month started near normal, but cooled to unusually low figures by the end of the first week – five degrees down! For a week from the 19th it was only two degrees below normal, then back to four degrees down at the end of the month.
Days were particularly cool, running about 29° instead of 33°.  However, the coolest days were not extreme.
The warmest day, Friday the 22nd, reached only 35.5°. The following morning was the warmest at 26.1°.
Dry air arrived from the south on the 24th, with a Dew Point of only 5.8°.
Rain fell frequently until the 19th, with the 6th being the wettest day (32 mm). The 29th was also very wet. There were nine rain days, totalling 115.6 mm. This is nearly twice the long-term February average of 66 mm.
Very few mornings were “Fine” (with no cloud).

 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.
