What to Wear in Ireland in March for Men?

Planning a trip to Ireland in March?

Get ready for a memorable adventure filled with rolling green hills, cobblestone streets, and plenty of unexpected weather.

The Emerald Isle is as charming as it is unpredictable, especially during early spring.

March marks the transition from winter to spring in Ireland, but don’t let the calendar fool you—it can still feel quite cold and wet.

So, how do you pack smart without overpacking or missing the essentials?

Understanding Ireland’s March Weather

Ireland’s weather in March is a bit of a mixed bag.

While the days start getting longer and a hint of spring enters the air, the chill of winter still lingers.

Average temperatures range from 4°C to 10°C (about 39°F to 50°F), and rain is pretty much a guarantee.

You might get lucky with a few sunny spells, but be prepared for drizzles, strong winds, and cloudy skies.

Understanding Ireland’s March Weather

Before thinking about outfits, it helps to understand what you’re dressing for. March in Ireland is famously changeable. On any given day, you might walk through sunshine in the morning and end up soaked by mid-afternoon. Average temperatures range between 4°C (39°F) and 10°C (50°F), with mild frosts at night and frequent showers throughout the day.

It’s All About Layers

Because the temperature can shift quickly, layering becomes your best friend. Start with a breathable base, like a cotton or merino wool t-shirt.

Add a sweater or lightweight knit for warmth, then top it off with a waterproof jacket. Layers let you adapt on the fly, which is crucial when you’re going from indoors to outdoors or sun to rain.

Don't Forget the Wind

March can be breezy, especially along the coasts or in open countryside. A windproof layer—ideally your outer jacket—will make a big difference.

Look for coats with tight closures, high collars, and adjustable cuffs to keep the chill out. You don’t want to be caught walking through Dublin or hiking the Cliffs of Moher with the wind cutting right through you.

Choosing the Right Outerwear

Your jacket is arguably the most important item you'll wear in Ireland in March. A stylish coat that's also functional will go a long way.

Waterproof Jackets Are Essential

There’s a reason locals always have rain gear handy. A good waterproof or water-resistant jacket is a must. Ideally, go for one with a hood and breathable fabric, like Gore-Tex or a waxed cotton coat. Whether you’re wandering around Galway or heading to the Giant’s Causeway, a reliable jacket keeps you dry without sacrificing style.

Consider a Lightweight Parka or Technical Shell

Heavier coats may be overkill unless you’re unusually sensitive to the cold. Instead, opt for a lightweight parka with an insulated lining or a technical shell that blocks out rain and wind. These types of coats are especially useful because they work well with layers and don’t feel bulky.

Bottoms That Handle the Weather

Your legs won’t get as cold as your upper body, but they still need protection from wind and wet.

Jeans and Chinos Work Well

Denim is popular and practical in Ireland, but choose heavier-weight jeans if you tend to feel cold.

Chinos are also a smart choice—they dry more quickly than denim and feel more comfortable in damp weather. Stick to dark, neutral tones like navy, grey, or olive, which hide rain splashes and dirt well.

Add a Pair of Waterproof Trousers for Outdoor Activities

If you’re planning any outdoor excursions—like hiking, cycling, or day trips in nature—pack a pair of packable waterproof trousers. You can easily pull them on over your regular pants when the rain starts. They're not the most fashionable item, but you'll be grateful for them when caught in a downpour on a trail.

Footwear That Can Handle Rain and Cobblestones

Ireland’s streets, especially in older towns and cities, are often cobbled or uneven. Add to that the constant threat of puddles, and choosing the right shoes becomes crucial.

Waterproof Boots Offer Function and Style

A pair of waterproof leather or synthetic boots is ideal for March. Look for something with decent tread to avoid slipping on slick sidewalks.

Chelsea boots, hiking boots, or insulated ankle boots can all work well, as long as they keep your feet dry and are comfortable for walking long distances.

Avoid Athletic Sneakers Unless Weather Is Dry

If you must bring sneakers, make sure they’re water-resistant and have sturdy soles. Otherwise, your feet may be cold and wet for most of the trip.

Sports shoes aren’t really suited to Ireland’s soggy March weather unless the forecast looks unusually dry—which is rare.

Smart Layering: Shirts, Sweaters, and More

Now let’s break down what to wear under your coat to balance comfort, warmth, and versatility.

T-Shirts and Long Sleeves as Base Layers

Start with a soft, fitted t-shirt or long-sleeve top. Merino wool is excellent because it’s insulating, breathable, and doesn’t hold odor. Cotton can work too, but it won’t keep you warm when wet. Avoid anything too loose—it won’t layer well and could trap dampness.

Mid-Layers Like Sweaters or Fleece

Over your base layer, wear a sweater or a zip-up fleece. Wool or wool-blend knits look stylish and insulate well, even when slightly damp. Go for classic crewnecks or quarter-zips in dark shades to stay versatile. If you're aiming for a smarter look for dining out or city evenings, a fine-knit jumper works great under a coat.

Collared Shirts for Added Style

Button-down shirts aren’t just for dinner or the pub—they add polish without sacrificing comfort.

Flannel, brushed cotton, or Oxford shirts all work well under sweaters. Bonus: You’ll fit right in with the Irish smart-casual style seen in cafes, museums, and shops.

Final Thoughts

March in Ireland is a beautiful time—quiet countryside, blooming daffodils, and fewer tourists.

But to really enjoy it, you need to dress smart. The key is flexibility: dress in layers, wear waterproof gear, and prioritize comfort.

You’ll stay dry, warm, and stylish whether you’re climbing castle steps or sipping Guinness by the fire.
