Where should you go in Northern Ireland in october when it comes to the weather?
Remember:
The climate in Northern Ireland in october ranges from tolerable to bad depending on the region and city.
That month is not the best month to visit North Ireland. The weather in Bangor (Strangford Lough district), Donwpatrick, Belfast, Larne and Ballycastle (Causeway Coast) is OK but just acceptable. The sun is not there all the time and you may be faced the rain regularly. Nevertheless, if you don't plan a beach and sun travel in North Ireland but rather cultural visits, this climate may be enough. In addition, there are definitely fewer tourists this month.
It's much worse in Enniskillen (Fermanagh), Derry (Londonderry) and Armagh and surrounding areas where the climate is even worse. We really do not recommend you to travel to these areas in october.
