On which planet does the regular occurrence of one phenomenon disprove the regular occurrence of another?
It can both be true that weather is locally different on most days but coincides to be universally cloudless on a fair number of hours every late-summer month (easily within a reasonable waiting time for an attacker)
The Netherlands covers 41,850 km2. I don't agree this size is small enough to cause the weather to be likely the same everywhere. Whatever qualifier and quantifier juggling you're trying to do is beside the point.

Nowhere there is the qualifier "a fair number of hours every late summer month". If you add arbitrary conditions of course you can get a different meaning.
