Not necessarily: an extreme wet or dull summer followed by an extreme warm winter would be the definition of a boring Autumn climate. We've not had routinely colder winters and hotter drier summers, which would make the climate seem more extreme.
Re dry months, and as an aside. It's interesting to look into the detail of the regional climate model projections for Western Europe, both in terms of timing and geographical variation. They do show wetter winters almost uniformly, but the modelled dry summers only cover Southern England and the continent. But more interestingly, the dry summer projection is for the 2050-2080 timeframe. On the time series I've seen (I'll try to dig them out) there is a bit of a bump up in summer rainfall in the first couple of decades before a steep decline. This kind of detail understandably gets lost when we tend to be shown just the end state. Right, now I have to get googling to find those time series.
