What to wear in Ireland in January

Before looking at what to wear in Ireland in January, it’s worth taking 10 seconds to get up-to-speed on what this month is like:

1. January is winter in Ireland

January is the middle of winter in Ireland with cold temperatures and short days. Throughout the month, the sun rises at around 8:30am and sets at around 4:40pm each day. Although Irish weather varies a lot from year to year, generally, January is wet, windy, and cold, with average temperatures of around 7°C/44.6°F. If you’re following one of the itineraries from our Irish road trip library, make sure to keep daylight hours at the front of your mind.

2. Hope for sunshine, prepare for showers

To get a better idea of what to pack for Ireland in January, it helps to look at recent conditions. In 2025, the month was cool and unsettled, averaging 5.4 °C. Rainfall split the country – drier in the North and Northwest, wetter in the South and East. Dublin Airport had just 13 rain days, while Belmullet (Mayo) logged 27. Snow fell in the South and Midlands early in the month, while storm Éowyn (Jan 24th) set new wind records, with hurricane-force gusts of 184 km/h at Mace Head in Connemara.

3. What’s chilly to locals may feel freezing to you

Where you’re from will play an important part in what you pack. One person’s ‘cold’ can be another person’s ‘mild’, so when you’re deciding what to bring with you, take this into account. If you’re not too sure how you will cope temperature-wise, again… layers are your friend!

4. We can get four seasons in a day

We’ve said it before and we’ll say it again, layering up is key. Yes, it’s January so you can expect it to be cold, but even in the depths of Irish winter, you can still have some mild and sunny days where your thick winter jacket will be a little too much. The key takeaway here – you never know what the weather in Ireland in January will be like.

List of what to pack for Ireland in January

Here’s what I’d suggest packing for Ireland in January (for women):

• Tops: Long-sleeve t-shirts, sweaters, and thermal base layers for insulation
• Bottoms: Jeans or lined trousers work best (add thick tights or leggings underneath for extra warmth)
• Footwear: Waterproof boots or sturdy walking shoes are essential for wet and cold days.
• Outerwear: A warm, waterproof winter jacket is a must. A packable down layer works well under it for really cold spells
• Accessories: Wool hat, gloves, scarf, and plenty of warm socks. A day bag for spare layers is handy
• Activity-specific gear: Hiking boots for trails, waterproof trousers for long walks, and swimwear if your hotel has a pool
• Evening wear: Ireland is casual – jeans and a nice top are fine. Bring one smarter outfit if you’re heading somewhere upscale

What to pack for Ireland in January (for men):

• Tops: Thermal base layers, long-sleeve shirts, sweaters, and a hoodie or fleece for warmth
• Bottoms: Jeans or heavier trousers. Thermal leggings under them are useful on colder days
• Footwear: Waterproof walking shoes or boots are essential for rain and muddy conditions
• Outerwear: A thick, waterproof coat (ideally insulated) to cope with wind and rain
• Accessories: Warm hat, scarf, gloves, and multiple pairs of wool socks. A small backpack for layers and essentials
• Activity-specific gear: Hiking boots and waterproofs for trails; swimwear and quick-dry towel if using hotel facilities
• Evening wear: Jeans with a shirt or polo work well. Pack one smarter option for fine dining

1. The essentials

The easiest way to decide what to wear in Ireland in February is to forget the clothing for a moment and start with the essentials, like:

• Passport: Top of every list, so check it well in advance
• Medication: Any prescriptions you need, plus a few painkillers like paracetamol or ibuprofen
• Adaptor: Ireland uses type G sockets (three rectangular prongs), so bring one if required
• Day bag: Ideal for carrying a change of clothes or stashing layers when the weather shifts
• Extras: A reusable water bottle, neck pillow, and any toiletries you use daily
• Driving specific: For those renting a car in Ireland, your driver’s licence is required for the rental company, and you’ll also need your licence and insurance details when driving in Ireland

2. The waterproofs

I talk about things to avoid in Ireland a fair bit on this website – one of the key points is not to assume the weather will be grand. In an ideal world, your January trip will be filled with dry weather, but realistically, there will be some rainy spells.

Bringing along a reliable waterproof jacket, waterproof shoes, and waterproof trousers can make wet days a lot more tolerable. If you’re heading to Ireland for a city break, then bringing a waterproof jacket and buying an umbrella once you arrive is also a good shout.

If you plan on exploring a lot on foot or hiking, it may also be worth purchasing a rain cover for your day pack to keep your things dry.

3. The frost-fighters

When debating what to wear in Ireland in January, a good way to begin is to start at your feet and work up to your head. With temperatures that can dip below freezing, you’re going to want to pack plenty of warm clothes to keep out the cold.

Numerous pairs of thick woolly socks, a warm hat, gloves, and a scarf are key and will help to keep your extremities nice and toasty. Other than this, I recommend (again!) layering up with items like vests, long-sleeve t-shirts, sweaters, and a nice thick coat.

If you don’t want to bring a bulky coat, then a packable feather-down jacket in between a waterproof jacket and a sweater also does the job. A great tip for women is to wear a pair of thick tights or even leggings under your pants to add an extra layer of insulation. 

4. The evening wear

When it comes to evening wear, restaurant and pubs in Ireland are quite casual. In most places, it’s more than ok for men to wear jeans with a shirt or polo shirt, and for women to wear jeans with a nice blouse or a light jumper. 

If you plan on hitting up one of Ireland’s many fine dining restaurants or a more up-market bar, then I’d recommend planning ahead and packing something a little more formal. 

5. The activity-specific clothing

If you’re planning on tackling one of the many hikes in Ireland, you’ll need specific gear – sturdy winter footwear, base-layers, and good-quality waterproofs are a must. 

If you love long walks along the coast, then bring some extra layers to shield you from the harsh winter winds. For those visiting cities in Ireland breaks, a comfortable pair of waterproof shoes are a must if you plan to discover attractions on foot. 

6. What to wear in Dublin in January

I get asked what to wear in Dublin in January all the time, and honestly it depends on what you’ll be doing. January is the coldest month of the year in Ireland, with short daylight hours, frosty mornings, and plenty of rain. Warmth and waterproofing should be your priorities. Here’s how I’d look at it:

• 24 hours in Dublin: If you’re sticking to the city centre, go for a heavy winter coat, warm layers, waterproof shoes or boots, and a hat and gloves
• 2 days in Dublin: For two days of sightseeing, casual but warm layers are best by day, with a smarter outfit for dinner or pubs in the evening under your coat
• 3 days in Dublin: If you’re heading into the Dublin Mountains or out to Howth, pack sturdy waterproof boots, thermals, a fleece, and a rain-and-windproof jacket
