Last year we had a few laps on the Friday evening, Sat weather was fine as was the track but on Sunday it was shite all day long and we stayed away, mist and rain this was at the beginning of May
The year before temp was around 30c for all 3 days, I had a Boxster S then and had the roof down all the time my head was as red a a lobsters aresole. this was also at the beginning of May, the week before we went they had snow.
Previous years we were there at the end of May and lost at least 1 day every year due to low mist and bad rain, the weather changes so quick you take
a chance whenever to go. fingers crossed that we all get lucky with the weather.
