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.
