The pattern we're in now has been so persistent that it hasn't been too difficult to be accurate - then again thats based on high probabilities rather than a reliable scientific analysis as well.
You say this as though you have been "accurate."
That's very difficult to assess because
A. We are only half way through June and any assessment of accuracy should surely wait till the end of summer or else you are patting yourself on the back before the work is done.
B. At different times you have said different things, always negative, but sometimes dry, sometimes wet.
C. In any case we had a pretty good first week of June (and a not do good second week). But to be accurate you would have had to have said that you expected summer to start with above average maximums, above average sunshine and below average rainfall. Which you didn't.
That's not to say that summer might not be miserable it might be (today won't win any prizes). Then again it might not. But how you can congratulate yourself for accurately predicting a three month period less than two weeks in is something of a mystery to me.
