What I can remember about last August was that it was wetter than average overall here in Edinburgh, but the beginning of August was wetter than the end of it. This meant that whilst we were already fairly close to the 1981-2010 average well before the end of that month, it was a bit of struggle on the end to get over that finishing line although we did just get there in the end.
The reason for that though, wasn't really because we were going on any sort of extended dry spells. What actually happened was that we kept on getting the same frequency of official rain days (a rain day being defined as one where we get 1 mm or more of rain), but the amounts of rain which we were getting on those days was now much smaller.
This meant that it was wetter than average during that month both in terms of the actual rainfall amounts, and in terms of the number of official rain days and since that was true during the rest of the summer months as well in this part of the world, that made for a rather poor summer overall.
Nevertheless, that relatively dry second half of August did mark the beginning of a drying trend overall, which then led us into a dry autumn (albeit with a slightly wetter than average September) followed by a drier than average winter where January was then, the only wetter than average month.
