This is all very region dependant now I think.
From a personal point of view, I'm in Cornwall, we've only had two deaths from covid19 here since May 4th, our one and only local hospital never reached full capacity and the South West has had the lowest numbers in the country.
We, as a family, have been going to the beach for a few weeks now, in fact I'm sat on one right now typing this. Beach is quite busy but no where near it would be on a normal sunny May bank holiday, seems to be mainly local and everyone is at least 5 meters away from each other. Not one single person on this beach will catch Coronavirus today, and the UV and Vitamin D benefits far outweigh any risk.
We could fully come out of lockdown today and I'm convinced that a 'second spike' will not happen, we barely had a first wave. The social and economic destruction this has already caused needs to be minimised.
