Daytime
You want a proper coat in Dublin in January, not a festival jacket. Wind makes the same afternoon feel sharper than the map suggests.
Outdoor time is the middle of the day. Finish plans before the light goes. Evenings are for indoors.
Rain
January is a wetter month in Dublin. Showers are part of the deal, not a spoiled surprise.
Waterproof shoes matter more than a rain plan for a beach, especially if a beach is not why you came. Build indoor hours into the afternoon.
