As recently as 1999. The difference then is that June wasn't
particularly good.
As discussed in another thread, if June and July are both good, August
tends to be as well. 1994 apparently broke that rule - I say
apparently, as I was out of the country for half of it - but apparently
Aug 94 was no better than average.

Wouldn't like to comment on the models other than the GFS suggests a
short, very poor spell of weather in a week's time, followed by
northerlies and then a high trying to build again, influencing western
and northern areas in particular.
