Dublin climate — mild, wet, and grey for 8 months
Dublin has a maritime climate: mild year-round but wet and overcast more often than not. Average temperature is 10°C. The city gets roughly 1,500 sunshine hours per year — about half of what Lisbon or Barcelona gets. Rain falls on 200+ days annually, though most of it is light drizzle rather than heavy downpours. Snow is rare (2-3 days per year).
The upside: temperatures almost never drop below 0°C in winter or rise above 25°C in summer. You won’t need heating or AC gear for your workstation. The downside: grey skies from October through March can affect your mood if you’re used to sunnier climates.

Best months for remote workers
May and June are the best months. Longest daylight (sunrise before 05:30, sunset after 21:30 in June), warmest temperatures, and the least rain. Dublin feels like a different city when the sun is out — parks fill up, outdoor dining opens, and the energy lifts.
September is underrated. Tourist crowds thin out, accommodation prices drop, but temperatures stay around 14°C. Good balance of work and exploration.
October through March is the long grey stretch. Workable, but plan for shorter days (sunset at 16:00 in December) and frequent rain. If seasonal darkness affects you, book a coworking space with good lighting rather than working from a dim apartment.
Avoid December-January if grey weather bothers you. These months average 2 hours of sunshine per day, and it rains 17-18 days per month.
What to pack
Non-negotiable: A proper waterproof jacket (not a fashion raincoat — one with sealed seams). Dublin rain is light but persistent, and an umbrella alone won’t cut it on windy days.
Layers: Temperatures swing 5-10°C within a single day. A merino base layer + fleece + waterproof shell covers every scenario from May through October.
For your gear: A waterproof laptop sleeve or bag. Dublin drizzle sneaks into backpacks. A compact power bank too — you’ll walk more than expected.
Winter (Nov-Feb): Add thermal base layers, a warm coat, and waterproof boots. Temperatures hover 3-7°C but the damp wind makes it feel colder.
Summer (Jun-Aug): Light layers plus a rain jacket. Shorts are optimistic — you’ll wear them maybe 10 days all summer.
