If you’re checking the temperature in Dublin Ireland right now, you’re probably staring at a number that looks a bit... underwhelming. Maybe it's 39°F (4°C) or hovering somewhere in the mid-40s. On paper, that doesn't sound like a deep freeze. But honestly? Dublin's weather is a liar. It’s a humid, maritime trickster that makes 40 degrees feel like 20 and a sunny morning feel like a distant memory by lunchtime.
Today, Friday, January 16, 2026, the city is sitting under a thick blanket of clouds. We're looking at a high of 46°F (about 8°C) and a low of 37°F (around 3°C). There’s a southeast wind kicking at 8 mph, and while the rain chance is low (10% during the day), the air is basically 86% soup.
That’s the thing about Dublin. It’s never just about the thermometer.

The Reality of the Temperature in Dublin Ireland
People come here expecting a scene from a Victorian novel—perpetual fog and bone-chilling frost. The truth is actually much milder, yet somehow more annoying. Dublin has what the experts call a temperate oceanic climate. Basically, the North Atlantic Current acts like a giant radiator that never quite turns off but also never gets truly hot.
The mercury rarely drops below freezing for long. In fact, seeing snow in the city center is such a rarity that the whole town usually grinds to a halt to take photos of a light dusting.
Right now, in the middle of January, we’re in the thick of the "cool season." This stretch usually runs from mid-November through late March. During this window, you’ll rarely see anything higher than 51°F (10°C).
What to Expect This Week
If you're out and about in the capital over the next few days, here’s the actual breakdown of the temperature in Dublin Ireland according to the latest readings:
- Saturday, Jan 17: We might actually see some sun! It’ll be partly sunny with a high of 45°F and a low of 36°F.
- Sunday, Jan 18: The rain returns. Light showers are expected with a high of 46°F.
- Monday, Jan 19: More of the same. Temperatures stay steady at 46°F during the day and 42°F at night.
- Tuesday, Jan 20: A bit of a jump in temperature to 47°F, but the wind picks up to 11 mph, making it feel significantly colder.
It’s consistent. It’s grey. It’s very Dublin.
Why the "Feels Like" Is the Only Number That Matters
You’ll notice on your weather app that there’s a "current temperature" and then a "feels like" temperature. In Dublin, always look at the latter. Currently, while it's 39°F outside, it actually feels like 36°F.
Why? Humidity.
Dublin is a damp city. When that 90% humidity hits your skin along with a breeze coming off the Irish Sea, the cold doesn't just sit on you; it sinks into your marrow. You could be wearing a parka, and you’ll still feel a nip.
According to Met Éireann records, 2025 was actually one of the warmest springs on record, but even then, the average mean temperature at Dublin Airport was only 9.5°C (around 49°F). We are a city of averages. We don't do extremes.
Seasonal Shifts: From Pints in the Sun to Wet Toes
If you’re planning a trip and trying to figure out the best temperature in Dublin Ireland for your visit, you have to weigh your tolerance for dampness.
The "Summer" (June - August):
July is technically the hottest month. You’re looking at average highs of 66°F (19°C). On a "scorcher," we might hit 75°F (24°C), at which point every person in the city immediately heads to Stephen's Green to get a sunburn. It’s glorious, mostly because the sun doesn't set until nearly 10:00 PM.
The Wildcard Autumn:
September and October are beautiful but damp. October is statistically one of the wettest months, seeing about 80mm of rain. The temperature starts its slow slide from 57°F down to 45°F.
The Winter Grind:
January and February are the coldest. We’re currently in the dip. The average low is around 38°F. It’s short days—only about 8 hours of daylight—and lots of "soft days" (that’s Irish for "it’s definitely raining, but we’re pretending it’s just a mist").
Dressing for the Dublin Forecast
Don't bother with an umbrella. Seriously.
The wind in Dublin comes in gusts—today it's 8 mph, but it’s not uncommon to see it hit 20+ mph in January. An umbrella will just turn into a useless metal skeleton within ten minutes. Instead, the "Dublin Uniform" consists of:
- A proper waterproof shell. Not water-resistant. Waterproof.
- Layers. The temperature can jump five degrees if the sun peeks out for three minutes, then drop again when the clouds roll back in.
- Leather or treated boots. The puddles here are legendary.
Actionable Takeaways for Navigating Dublin Weather
If you are currently looking at the temperature in Dublin Ireland and trying to decide what to do today, keep these three things in mind:
- Check the wind direction. A south wind (like we have today) is usually milder. A west wind brings the rain, and a north wind brings the "actual" cold.
- Plan indoor backups for the 3:00 PM slump. The sun starts to fade early this time of year (around 4:30 PM), and that’s usually when the dampness feels heaviest. It’s the perfect time for a museum or a snug in a pub.
- Watch for the frost. While it's 46°F today, later next week (Friday, Jan 23), the temperature is expected to drop back toward 35°F with a chance of rain and snow. If you're driving toward the Wicklow Mountains or the outskirts, expect icy patches even if the city center looks clear.
Dublin isn't a city that demands a parka, but it is a city that demands respect for the damp. Keep your feet dry, watch the "feels like" stat, and remember that a pint of stout tastes better when it’s 40 degrees and grey outside anyway.
