Mackerel in Dunmore East

Was in Dunmore East for the weekend and got about 40 minutes to fish from the end of the pier using a small wedge lure.
On the second cast I took in a small mackerel which suprised me... I thought it would be far too late in the year for any mackerel to be still inshore.
Is it a late season or am I just mistaken?

i was on them in Wexford today, on plug lures couldnt miss them for about an hour or so, frustrating cause I wanted large bass
