Dermot - I'm about 2.5 hours inland from VA beach - we will have a high of 18-19C, so a tad cooler than the last time I was in Ireland in July, but still, way, way warm for this time of year here. Purportedly this is due to El Nino weather pattern, which keeps pumping lots of warm gulf weather our way - keeping the jetstream north and west of us.
I need a wetsuit!
