Good news: Although it is not perfect the weather in North Ireland that month is, on average, pretty good in Bangor (Strangford Lough district). I allows to enjoy vacation in this city. And even why not take a little time to lazing in the sun!
If you do not go lazing in the sun, but, for example to go sightseeing, the cities of Donwpatrick, Belfast, Larne and Ballycastle (Causeway Coast) have a decent enough weather for that in july.
