Oh now come on, depends on how you are measuring.
According to that big yellow thing in the sky, midsummer is June 21/22...so we are indeed in summer astronomically.
Those nice weather people at the met office count June, July And August as summer, so again that is another pedantic point to Austin.
personally, as an outdoor worker dealing with nature, due to climate change and general weather faff of the highest order, most outdoor workers count May, June July and August as the summer season, so to some, the summer is a month old, and we have been using sunscreen for longer than a month.
Personally, due to individual circumstances...it is towards the twelfth night of Christmas, so early January.
And back on topic yet again, merely to avoid whipping, it is bloody summer.
It is now peak season, school trip zone with leavers and students, with pass holders aplenty.
Flats have gone, other stuff should be compensating...
