Planning a Trip to Dublin? Here's the Weather

See what weather to expect in Dublin, Ireland and plan your trip with confidence. Monthly averages from real historical weather data.

Dublin's climate is famously mild and famously damp — temperatures rarely punish you in either direction, but rain is a near-constant companion across every month of the year. Highs peak around 19°C in the warmest stretch and dip to around 8°C in January, making this a city best explored in layers rather than sunscreen. The upside: the city's parks and waterfront paths are genuinely pleasant when the weather cooperates, and a good café is never far away when it doesn't.
