Comparing November months

On average, the month was not quite as hot as November 2009, the hottest this century. The air was again very dry, with an early morning dew point of 7.1°, a little higher than the lowest value (5.7°) recorded for November last year.
Following only three years after the wettest November on the 130-year record (242.9 mm), the total rainfall of only 24 mm was in the 15th percentile. That is, such low November rainfalls happen about one year in seven. However, the time since a lower November rainfall (15 mm in November 1990) is thirteen years: the longest gap ever.
For the third month in a row, little changed in rainfall totals for periods of more than one month. There is no longer a serious shortage in the 6-month total (now in the 10th percentile) but there are now serious shortages in the totals for 5 months (9th percentile), 9 months (8th percentile), 15 months (6th percentile), 18 months (6th percentile), and 30 months (9th percentile). There is one severe shortage: the total for 12 months (393 mm) is in the 4th percentile.
