Mostly yes, if the weather does not put you off. October in Dublin is Lively on the typical day, and not one of the 31 days in our window is crowded enough to call Busy. Expect around 14 °C by day, with rain on about 18 days. The crowd comes with the school holidays in Germany. Late October is the month's quietest stretch in Dublin — the typical day at 50%, against 55% in mid October. The crush is at Temple Bar's cobbles at night; the quiet is at the Georgian squares. The calmest day is Friday 1 October, the busiest Monday 25 October.
In short, a solid middle-ground pick.
Of the 12 months we forecast for Dublin, October is the quietest. Its heaviest day is Mon 25 Oct, busier than 61% of the year; its lightest is Fri 1 Oct at 48%.
