Each month the Town Hall publishes Cápito's summary of the previous month's weather. Here is my summary of his summary.
In May we got eighteen days of sunny and cloudless skies and another twelve with sunny spells - that leaves just one sunless and cloudy day. The highest temperature, of 38ºC, was recorded on the 14th of May - that was one of the seven days when the temperature got above 30ºC. The lowest temperature was 5ºC on the 23rd May which was one of the five days when temperatures dropped below 7ºC. The mean maximum across the month was 27ºC and the mean minimum was 11ªC. We got 10 litres of rain per square metre for the whole month but 7 litres of that fell on the 7th. Rain fell on just three days across the month.
I agree, it's desparate isn't it?
