For cooler months, bring layers and a warm jacket (January averages 6.1°C). A waterproof jacket or umbrella is recommended year-round as Dublin receives 945.0mm of annual precipitation. Sun protection is important, especially during months with high UV index.
Dublin's weather is a choose-your-own-adventure where every chapter includes rain. I packed a 'waterproof' jacket once — it wasn't. Bring serious rain gear: Gore-Tex or equivalent, year-round. The good news: rain rarely lasts long. My favorite window is May-June: 15°C, 7 hours of sun, and the pubs still have that winter coziness. August can be oddly humid. Skip January — 5°C, 70mm of rain, 8 hours of daylight if you're lucky. October has a melancholic charm but bring layers. Always pack for four seasons in one day, genuinely.
