The fortunate thing about ozone "holes" is that the mechanism is such
that, AIUI, they can only occur in winter. Even with the hole, the
amount of dangerous solar radiation you will receive in Edinburgh at
this time of year, when at midday the sun will be no more than about 15
degrees above the horizon, is I imagine likely to be considerably less
than you would get there at mid-summer with a full ozone layer.
