You'd have to be very hardy to do this in England & I doubt that there are any nudist beaches in Scotland.
When the English pay a visit to the coastal areas of this island, they usually take beach wear & a towel plus thermals, jumpers, welliington boots, a little gas stove, waterproofs, sleeping bags, a ski jacket - you name it, we take it. The womenfolk of England like to be prepared for every eventuality which is just as well as our weather can turn from burning sunshine to hail in the blink of an eye!
This adaptibility is why cardigans will never go out of fashion in the UK ;-)
Jane, thank you for this wonderful card - good luck!
