The capsule
01Aran sweater or mid-weight wool sweaterDublin peak summer still runs 12°C / 54°F mornings climbing to 21°C / 70°F afternoons per Met Éireann at Phoenix Park. The Aran sweater (hand-knit on Inis Mór, Inis Meáin, Inis Oírr in undyed cream or oat) carries the morning chill across Trinity College and the Phoenix Park 8am walk; lighter merino from Aran Sweater Market on Nassau Street works for the warmer afternoons.
02Cotton/merino-wool blend long-sleeve baseThe 9°C / 16°F July daily swing the Met Éireann records at Phoenix Park rewards layering. Sage or oat merino strips down by Bewley's (Grafton Street, since 1840 — refurbished and reopened 2017) 1pm coffee, layers back up when the Atlantic wind picks up at Sandymount Strand by evening.
03Packable rain shell — Patagonia, Magee 1866 wax-cottonDublin July logs 13 rain days totalling 65mm — the Atlantic-coast climate keeps Dublin wetter than Mediterranean July by a wide margin. Magee 1866 (Donegal since 1866) wax-cotton handles the lighter bursts; Patagonia Torrentshell ($150) packs flat for the Trinity-to-Phoenix Park daily run.
04Tailored straight-leg trousersHeather or oat wool trousers from Magee 1866 (Donegal handwoven tweed since 1866) carry the Trinity College quad walk and the trad-session pub run at O'Donoghue's (Merrion Row, the Dubliners' heritage trad pub since 1934). The Atlantic wind keeps Dublin 4-6°C / 7-11°F cooler than London at peak summer — wool not linen.
05Structured leather bootsTrinity College quad is uneven cobble; Temple Bar lanes slick after even light rain; Cliffs of Moher cliff path (3.5 hours west, doable as long day-trip) is hardpack stone with severe Atlantic wind. Loake (Northamptonshire 1880) ankle boots in oxblood or chestnut survive the lot. Skip leather sneakers on the Wicklow Mountains Glendalough hike.
06Magee 1866 Donegal tweed jacketDublin July evenings drop to 12-14°C / 54-57°F as the Atlantic wind pushes through Sandymount and the Liffey. Magee 1866 (Donegal since 1866) tweed jacket in heather grey or bottle green layers over the Aran for Chapter One (Dublin, 1-Michelin since 2007) 19:30 booking; the handwoven Donegal flecks signal Irish heritage at the table.
07Cotton or wool button-downChapter One (1-Michelin since 2007), Glovers Alley (1-Michelin), and Patrick Guilbaud (2-Michelin since 1981 at the Merrion Hotel) all run smart-casual. A cream cotton or oat wool button-down tucks under the Magee tweed jacket; works for a pint at The Brazen Head (Dublin's oldest pub, since 1198) after.
08Avoca scarf + crossbody + sunglassesAvoca (Wicklow 1723, Ireland's oldest working woolen mill) wool scarf in sage or terracotta handles the Atlantic wind drop at Howth Head by 8pm. Strathberry crossbody at Brown Thomas (Dublin 1849) works hands-free across Trinity cobble. Polarized sunglasses non-optional — July daylight runs 16h 30m with low Atlantic sun bouncing off the Liffey through 9pm.
