We have cloudless sky here right now and have seen a few tonight. The problem is that the moon has just come up and although not full is still quite large and bright so makes it more difficult to see. There was someone on BBC Breakfast this morning who said that they actually start in late July peaking from today & over the next couple of days, trouble is tomorrow night we have cloud/rain forecast. Might be worth a look in the early hours (if I wake up to ‘spend a penny’ 
#-o ).
