Dublin in January is... well, it’s a mood. Honestly, if you’re looking at the 10 day forecast Dublin Ireland, you’re probably seeing a lot of grey icons and wondering if you should just stay in the pub. You shouldn't. But you do need to know that the "light rain" mentioned on your phone is often more of a horizontal mist that finds its way into your soul if you aren't prepared.
Right now, as of January 16, 2026, the city is sitting at a crisp 42°F. It feels like 36°F because the wind is coming off the Irish Sea from the southeast at about 8 mph. If you’re standing on O’Connell Bridge, that damp air bites.
The Next 10 Days: A Breakdown of the Damp and the Cold
Basically, the upcoming week is a classic Irish winter "mixed bag." We aren't seeing any massive "Beast from the East" snowstorms yet, but there’s enough moisture to keep things interesting.
The Immediate Outlook
Tonight is looking pretty soggy with a 100% chance of rain. Temperatures will hover around 41°F. If you’re heading out to Temple Bar, bring the heavy-duty coat.
The Weekend Shift
Saturday, January 17, actually looks like the "dry" day of the lot. We’re talking mostly cloudy with a high of 46°F and only a 20% chance of rain during the day. It’s probably your best window for a walk through St. Stephen’s Green without getting drenched. Sunday follows a similar pattern—partly sunny highs of 46°F—but don't get too comfortable. The rain returns by Sunday night.
Mid-Week Realities
Monday through Wednesday (Jan 19–21) is where it gets typical. Highs will stay steady at 47°F, but the rain chances creep back up. Interestingly, Monday night has a 40% chance of snow as the temperature dips to 40°F. Now, in Dublin, "snow" usually means a brief slushy mess that disappears before you can find your camera, but it’s enough to make the morning commute a bit of a nightmare.
Tuesday, January 20, is the one to watch. There is a 65% chance of snow during the day, though with a high of 46°F, it’ll likely struggle to settle. Expect the wind to kick up to 13 mph from the southeast, making it feel significantly colder than the thermometer suggests.
Why the Dublin Forecast Always Seems to Lie
You've probably noticed that the 10 day forecast Dublin Ireland changes every six hours. There’s a reason for that. Met Éireann, the national weather service, often deals with "unsettled" low-pressure systems tracking right over the island.

According to their latest extended range report, the week of January 19 to January 25 is dominated by a southeasterly airflow. This means above-average rainfall for the East Coast. While the west of Ireland sometimes gets the worst of the Atlantic gales, Dublin gets this persistent, drizzly dampness.
Expert meteorologists like those at the Irish Meteorological Service point out that while temperatures are currently "around normal," they fluctuate wildly based on the exact track of these low-pressure systems. If a system shifts ten miles to the north, you go from a dry afternoon to a washout.
Dealing with the Humidity and the "Real Feel"
Dublin's humidity is currently sitting at a whopping 88%.
When the air is that saturated, 42°F feels much colder than 42°F in a dry climate like Denver or Madrid. The dampness gets into your clothes. It’s why you’ll see locals wearing layers of wool rather than just one massive puffer jacket.

Packing for the 10-Day Reality
If you're coming to the city this week, forget the umbrella. Dublin wind tends to turn umbrellas into expensive modern art sculptures within minutes.
- The Base Layer: Get some thermal leggings or "long johns." Even under jeans, they make a massive difference when the humidity hits.
- Waterproofing: You need a shell that is actually waterproof, not just "water-resistant."
- Footwear: Leather boots or treated sneakers. The cobblestones in Temple Bar are slippery when wet, and puddles in Dublin are deceptively deep.
- The Scarf: This isn't a fashion statement; it's a structural necessity to keep the wind from whistling down your neck.
What to Expect Toward the End of the Month
Looking further ahead toward January 25, the temperatures stay low, with highs of 43°F and lows of 38°F. The wind is expected to pick up to 16-17 mph.
There is a significant 75% chance of rain on Sunday, January 25. Basically, the month is ending exactly how it started: grey, damp, and perfectly suited for a slow afternoon in a cozy corner of a library or a snug.

While the "Arctic blast" mentioned in some early January news reports hasn't fully paralyzed the city, the "Status Yellow" warnings for wind and rain are frequent this time of year. Always check the Met Éireann app right before you leave the house—not three hours before.
Actionable Next Steps:
- Download the Met Éireann app: It’s more accurate for local Irish microclimates than the generic weather app pre-installed on your phone.
- Check the wind direction: A "Southeasterly" wind in Dublin means the chill is coming straight off the water—dress 5 degrees colder than the forecast says.
- Plan indoor backups: If you were planning on the Guinness Storehouse or the Epic Museum, Monday or Tuesday (the snow/rain mix days) are the days to do it.
- Waterproof your gear: If your jacket hasn't been treated in a while, grab a waterproofing spray before the Sunday night rain hits.
