Monthly commentaries for 2011

December 2011 was very mild and very wet. The average temperature of 6.7°C was exactly two degrees above the long-term average, and rainfall at 133.7 mm was 83% above normal. Only one day (the 18th) recorded a frost, and that was a mere -1.1°C. In contrast, the overall mean temperature for December 2010 was -0.8deg;C.

November 2011 was very mild and dry, the third unusually mild month in a row, completing a very warm and rather dry Autumn. There was only one night with a frost, and the average daily temperature was well into double figures until the last few days of the month, when a cold front came through bringing 30+ knot gusts, hail and 6mm of rain in a couple of hours. This pulled the average down to 9.8°C, still a remarkable 3.3°C above the long-term average. Rainfall at 39.8 mm was only 56% of average.

October 2011 was very mild and rather wetter than average. The mean temperature of 12.8°C was 2.7 degrees higher than the norm, though (as in September) more as a result of mild nights than hot days. The first half of the month was exceptionally warm, however, with a max of 28.2°C on the 1st, and minima generally well into double figures until the 14th, and no frost recorded.

September 2011 was warm and dry, quite a change from the previous four months. The average temperature of 15.1°C was 1.8 degrees higher than average, though more as a result of mild nights than hot days, while rainfall at 31.6mm was less than half the norm. The last few days were however exceptionally warm, with 27.5°C on the 30th. [1. October turned out to be the hottest day of the year, hotter than any day during the summer].

August 2011 was the fourth wet month in a row at Acton Bridge, with 75.1 mm of rain, 16% above average, and making the first eight months 4% wetter than the norm. August was conspicuously cloudy and had 25 "rain days" (0.2mm or more) and two storms, on the 10th and the 26th / 27th. The overall temperature was remarkably steady, with few excursions below 10°C or above 20°C. Because there was only one really hot day (3rd, max 26.4°C), the month felt cool, although it actually averaged 15.4°C, just half a degree below the 30-year norm.

July 2011 was the third wet month in a row at Acton Bridge, with 69.8 mm of rain, 31% above average, and making the first seven months 3% wetter than the norm. Most of the month's rainfall occurred in two brief spells, especially around the 17th with an inch in 24 hours, and the last nine days recorded none at all. Apart from cooler periods associated with the rain, the overall temperature was steady and ended up half a degree below average.

June 2011 was another comparatively wet month at Acton Bridge, with 80.5 mm of rain, 32% above the 30-year average of 60.9mm, bringing the first half of the calendar year to 98% of the norm. Despite a few very warm days towards the end of the month (reaching 27.6°C on the 26th, and 27.9°C on the 27th) the overall temperature was just 0.1°C above average.

May 2011 was comparatively wet month at Acton Bridge, with 69.4 mm of rain, 32% above the 30-year average of 52.5mm. May was also rather mild, averaging 12.1°C, which is 0.7°C above the norm. There was no air frost during the month.

March 2011 was exceptionally dry at Acton Bridge, with only 16.7 mm of rain, half of which fell in the last two days of the month.
