Pre-emptive

I had it in my mind that the summer solstice is today the 21st but when 
I checked the internet it is tomorrow at 10.47am.  Well I had already taken the photo and gone to the effort  of using the tripod and the self timer so I'm not going to do it all again tomorrow.   It is 21 c or 69.8 f and warm enough for a first swim but there is a blustery wind and I'm told I am a princess so only perfect conditions will do.
