Until the 25th, August had been a much dryer month with only 17.2mm falling and the warmest day of the summer was recorded on the 19th when 31.3°C was reached. Then Cambridge caught some intense falls of rain during the afternoon of the 25th with hail and a considerable amount of thunder. During the three and a half hours of storm we saw 49.4mm fall. This intensity of rain inevitably caused local flooding and the tide marks of debris that had been washed about could be seen all over the Garden during the following days. It is probable that this is the greatest 24hr fall for some time and will probably be the heaviest for this year.
This brought August to a total of 76.1mm, and so far this year we are now on 550.5mm.
