I think he means by British standards which is not completely overcast, pouring rain or too foggy to see your way to the observatory. There are many nights here that are not cloud free, but still fine for observing. I have done good summer UBV photometry with thunderstorms all around and the observatory continually being lighted up from the lightning flashes. There were large holes in the clouds with very clear and steady sky. Those nights would surely qualify as clear relative to what the British normally see.
