You’ve probably heard the jokes. Dublin weather is basically four seasons in the span of a lunch break. Honestly, after living through enough Irish winters, I can tell you that the "wet and grey" stereotype is only about half the story.
If you're looking at the 10 day weather Dublin forecast right now, you’re likely seeing a lot of little cloud icons with raindrops. It looks dismal on paper. But here’s the thing: Dublin rain is rarely a monsoon. It’s more of a "persistent mist" or a "soft day," as the locals call it.
The Current Reality on the Ground
Right now, we are sitting in a classic January pattern. As of tonight, January 18, 2026, it’s about 43°F out there. It feels a bit nippier—around 38°F—thanks to a southeast wind blowing at 8 mph.
If you’re heading out for a pint or a late-night walk near St. Stephen’s Green, it’s mostly just partly cloudy. Nothing crazy. But the next few days are where it gets interesting because Met Éireann has been chatting about a fairly rare fog event.
What the Next 10 Days Actually Look Like
Don't just look at the high temperatures and think you’re fine. In Dublin, the humidity (currently sitting at a damp 88%) makes the cold "seep" into your bones. Here is the breakdown of what to expect for the rest of the week.
Sunday, January 18: We're looking at a high of 47°F. It’ll be cloudy for the most part during the day, but as the sun goes down, expect some light rain. The wind is coming from the south at 8 mph, which is relatively gentle for us.
Monday, January 19: This is where it gets tricky. We’ve got a high of 46°F and a low of 38°F. There’s a 35% chance of light rain during the day, but keep an eye on the night forecast—there’s actually a 20% chance of snow. Southeast winds will pick up to about 12 mph.
Tuesday, January 20: Tuesday is looking pretty wet and windy. Highs of 46°F and lows of 41°F. The wind is going to gust up to 21 mph from the southeast. We have a 35% chance of snow during the day and a much higher 65% chance of rain at night. It’s a "stay inside" kind of day.
Wednesday, January 21: Expect more of the same, with a high of 47°F and a low of 44°F. The wind stays strong at 22 mph. There’s a 45% chance of rain during the daylight hours, dropping slightly to 35% at night.
The Rest of the Week (Jan 22–27):
The temperatures start a slow slide downward. By the time we hit next Tuesday, January 27, we’re looking at highs of only 41°F and lows of 37°F.
- Thursday offers a brief break with some "partly sunny" intervals and a high of 47°F.
- Friday through next Tuesday is a very consistent run of light rain with chances hovering between 25% and 35%.
Basically, if you’re planning to be in the city, just assume you’ll get damp at some point.
10 day weather Dublin: Surviving the "Damp"
People get obsessed with the temperature. "Oh, 45 degrees isn't that cold," they say. Then they spend twenty minutes standing on O’Connell Street waiting for a bus and realize they can't feel their toes.
The wind off the Irish Sea is no joke. Even a 15 mph wind from the east (which we’ll see toward the end of next weekend) can make 42°F feel like it’s freezing.
Why the Fog Matters
Met Éireann has been highlighting a strange atmospheric phenomenon—a persistent fog pattern. Usually, fog burns off by 10:00 AM. However, due to light southeasterly breezes and settled nights, we’re seeing "dense fog" warnings. If you’re driving out toward the Wicklow Mountains or even just navigating the M50, it can be genuinely dangerous.
The Dublin Rainy Day Strategy
Since the 10 day weather Dublin forecast is dominated by a "light rain" and "cloudy" outlook, you need a plan that doesn't involve shivering under a broken umbrella.
The Museum Pivot: The Little Museum of Dublin is right off St. Stephen’s Green. It’s tiny, quirky, and undercover. If the rain starts, duck in there for a 30-minute guided tour.
The "Vintage Bus" Hack: There’s a 1960s double-decker bus that does afternoon tea tours. It’s basically a moving cafe. You see Trinity College and Phoenix Park while eating scones and staying bone-dry.
George’s Street Arcade: One of the oldest shopping centers in the world. It’s covered, it’s red brick, and it has everything from vintage clothes to great falafel at Umi.
Whiskey Over Beer: The Guinness Storehouse is great, but the Jameson or Teeling distilleries are perfect for "thawing out." Nothing beats a Dublin winter like a neat pour of something local.

Actionable Insights for Your Visit
If you are looking at this forecast and feeling discouraged, don't be. Dublin in January has a specific kind of cozy energy that you don't get in the summer.
Pack a "Dry Bag": Forget a heavy coat that gets waterlogged. Go for a high-quality waterproof shell over a fleece. You want to be able to peel layers off the second you walk into a heated pub.
Footwear is King: Leather or treated boots are a must. Canvas sneakers will be soaked through within three blocks of walking in "light rain."
Check the "Feels Like" Temp: Always look at the wind speed. On Wednesday, Jan 21, that 22 mph wind will make the 47°F feel significantly colder.
Timing your walks: According to the current data, Thursday, Jan 22, is your best bet for outdoor photos. It’s the only day with a "partly sunny" rating in the next stretch. Save your Phoenix Park deer-spotting or your coastal walk in Howth for that window.
The reality of the 10 day weather Dublin outlook is that it’s predictable in its unpredictability. It’s rarely extreme, but it is persistent. Embrace the grey, find a snug in a pub with a real fire, and remember that the rain is why the grass is that ridiculous shade of green in the first place.
Keep an eye on the southeast winds specifically toward the end of the month—they tend to bring a sharper chill than the westerly Atlantic breezes. If the humidity stays above 80%, which it's projected to do, that dampness will be your main opponent. Layer up, stay dry, and enjoy the city.
Next Steps:
- Check the hourly wind chill before heading to the coast, as east winds make temperatures feel 5-10 degrees colder.
- Book indoor attractions like the Guinness Storehouse or EPIC Museum for Tuesday and Wednesday when rain chances are highest.
- Monitor Met Éireann's fog alerts if you have early morning travel plans involving Dublin Airport or regional driving.
