2014 weather was as follows (checked photos to try and remember but might not be spot on).
I arrived early afternoon Thursday 26th June - light rain soon after arriving with intermittent showers throughout the afternoon with one heavy one although I think the evening was ok. Ground was quite muddy in places but not terrible and some areas still fine. Temps mild.
Friday 27th was ok for most of the day with some sunny spells and periods of light rain. Then around 6ish it absolutely chucked it down with hail as well. Total mud bath after that.
28th June Saturday. Very muddy on site but I don't think it rained again, or if it did it was not a lot. Again, mild temps.
Sunday 29h June - sunny and most of the site managed to dry out ok.
Monday fine and sunny
