Quick change into autumn

Misty morning

Alvechurch amateur weatherman Phil Thomas records the changes.

As we went to press, September had fallen short of what was expected. Temperatures had been forecast to be warmer than normal but by the 16th, the mean temperature was only 13.3C – that’s 0.6C below the long-term local mean.

Rainfall was below normal with only 30% of the mean rainfall by the halfway point in the month. Sunshine was variable, with a few warm sunny days making the month seem better than it actually has been.

September 2015 (to the 16th)
Mean Max   17.4C 0.8 below average
Mean Min   9.2C   0.4 below average
Mean       13.3C   0.6 below average
Rainfall     18.2mm   30% of average
Sunshine 60.6 hours 46% of average

August was quite an average month with little in the way of extremes. Daytime temperatures were way below the average due lack of sunshine: only 74% of the entire month’s long-term local average.

Rainfall for the first 12 days was very low with only 1.1mm over this period. This was more than made up for with the very heavy rainfall on the night of the 13th/14th, with 26.4mm in only 8 hours – the wettest 12-hour period this year.

The rest of the month stayed changeable, cold and wet.

August 2015
Mean Max   20.1C   1.1 below average
Mean Min   11.6C   0.1 below average
Mean       15.9C   0.5 below average
Rainfall   92.2mm   177% of average
Sunshine 111.5 hrs 74% of average

After a warm, dry and sunny June, the rest of the summer was a typical British summer with a mixture of all seasons. Rain, hail, thunder, cold, and one very hot day: 31.9c on July 1st.

Summer 2015 (June, July, August)
Mean Max   20.6C   0.5 below average
Mean Min   11.2C   0.5 below average
Mean       16.0C   0.5 below average
Rainfall   218.8mm   127% of average
Sunshine 473.1 hrs 107% of average

Outlook
The outlook as we go into October seems little different, with some brighter days but a lot of showery cooler spells.

Further on, the computer models do not agree – so I suspect it may even be drier than normal, and possibly milder.
