What to wear in Ireland in May
Before looking at what to wear in Ireland in May, it’s worth taking 10 seconds to get up-to-speed on what this month is like:
1. May is spring in Ireland
May is generally one of the best times to visit Ireland, thanks to its long days and usually OK weather. May has average highs of 15°C/59°F and average lows of 9°C/48°F. In the middle of the month, the sun rises at 05:17 and sets at 21:26. If you’re using one of the itineraries from our Irish road trip library, these long days give you lots of time to explore!
2. Prepare for every kind of weather
May is right on the cusp of summer in Ireland, so usually, the weather is quite good. However, the weather in Ireland regularly throws you a curveball. To get a better idea of what to pack for Ireland in May, it helps to look at recent conditions. In 2025, it was one of the warmest and sunniest Mays on record. Dublin Airport saw 13 rain days and 11 wet days, while Valentia Island (near the Ring of Kerry) had just 5 wet days, among the driest on record.
3. Pleasant here, but still on the cool side for many
It may be “find old weather” for us, but everyone handles the cold differently, and where you’re from definitely plays a part. If you’re from a cold country, then May’s temperatures will be more than manageable, but if you’re from a tropical climate, you might want to pack some extra layers just in case.
4. We can get four seasons in a day
In Ireland, it’s not uncommon to be basking in the sunshine one moment and then sheltering from a downpour the next. During May, you can easily encounter wind, sunshine, and rain in the span of a few hours, that’s why we’re adamant about layers and waterproofs, so you’re prepared for every scenario.
List of what to pack for Ireland in May

Here’s what I’d suggest packing for Ireland in May (for women):
- Tops: Light layers for mild spring days. Think t-shirts, breathable blouses, and a thin long-sleeve/cardigan for cooler evenings (May averages ~15°C/59°F by day, ~9°C/48°F at night)
- Bottoms: Jeans or light trousers for most days; add a summer skirt or casual dress. Pack one pair of shorts if the forecast looks warm
- Footwear: Comfortable walking shoes or trainers are essential; waterproof or water-resistant is wise for showers. Casual flats for evenings
- Outerwear: A lightweight, packable waterproof jacket for on-off rain. A light fleece or thin insulated layer if you feel the cold
- Accessories: Sunglasses and sunscreen (long daylight, strong glare on clear days), a cap/sunhat, compact umbrella, and a small day bag for stashing layers
- Activity-specific gear: Hiking shoes/boots with grip for trails, thin waterproof trousers if you’ll be outdoors a lot, and swimwear/quick-dry towel for pools or beach stops
- Evening wear: Ireland is casual – jeans or a simple dress works. Bring one smarter outfit if you’ve booked upscale dining
What to pack for Ireland in May (for men):
- Tops: Breathable t-shirts or polos for daytime, plus a lightweight long-sleeve or thin knit for cooler nights
- Bottoms: Chinos or light trousers for most days; pack shorts if the forecast looks decent or you run warm
- Footwear: Supportive walking shoes/trainers (preferably water-resistant) for city exploring and light hikes; a cleaner pair for evenings
- Outerwear: A slim, packable waterproof shell for passing showers; add a light mid-layer if temperatures dip
- Accessories: Sunglasses, sunscreen, a cap, compact umbrella, and a daypack for layers, water, and snacks
- Activity-specific gear: Hiking boots for longer trails, thin waterproof trousers if you expect rain, and swimwear for hotels or sea dips
- Evening wear: Jeans/chinos with a shirt or polo fit most pubs and restaurants; include one smarter option for finer places
1. The essentials

With any Ireland packing list for May, the essentials are always a good place to start. Of course, what you consider essential might not be the same as what I consider essential, but here are a few things I recommend starting with:
- Passport: Check it’s valid before you travel – it sounds obvious, but plenty of people only realise it’s expired at the airport
- Tech: Phone, camera, laptop, and chargers. Ireland uses G-type sockets (three rectangular prongs), so bring an adaptor or two
- Medication: Any prescriptions or hard-to-find meds you rely on should be packed, as you may not get them here
- Toiletries: You can buy most things in Ireland, but if you use something specific, it’s worth bringing it with you
- Day bag: A must if you’re out exploring. Perfect for carrying snacks, stashing away layers, and keeping your essentials in one place
- 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

We chat about what to avoid in Ireland a fair bit on this website – one of the key points is not to assume the weather in Ireland in May will be grand.
As we said earlier, May in Ireland is a mixed bag of sunshine and rain. So even if the forecast is predicting sunshine, we highly suggest bringing along some waterproofs.
Since the weather will be warming up, a light waterproof jacket over some layers should be enough to keep you warm and dry. If you plan on going on some walks or hikes, then waterproof trousers are also a good shout.
For city trips, a small umbrella is a great add-on, you can buy one once you arrive and they shouldn’t take up too much space in your day bag.
3. The bits for keeping out the cold

When it comes to what to wear in Ireland in May, a lot of people think heavy layers aren’t necessary, and for the most part, they’re right.
By this stage of the year, it’s usually mild enough to leave the bulky winter coat, thick socks, hat, and gloves at home. Instead, focus on lighter layers like vests, t-shirts, and jumpers or hoodies that you can add or remove as needed.
If you’re unsure how you’ll cope with cooler days, a packable feather-down jacket and a light scarf are good insurance.
For women, May is also when sundresses and maxi skirts start to come into their own.

4. The evening wear

From my guide to the best pubs in Ireland
In Ireland, evening wear is usually on the casual side. For men, jeans or chinos with a light shirt or polo work just fine, while women often go for casual dresses or jeans with a nice top.
This kind of outfit is perfectly acceptable for most pubs in Ireland or even a relaxed night out. That said, if you’re planning dinner in a formal restaurant or drinks in a high-end bar, it’s worth packing something a little smarter.
5. The activity-specific clothing

Although there’s endless things to do in Ireland, May is one of the better times of the year to tackle some of the various hikes in Ireland.
While there are heaps of short and sweet beginner-friendly trails throughout the country, more challenging routes will require some decent footwear.
You may also want to bring some sunglasses and, as we mentioned earlier, light waterproofs.
Cities in Ireland are generally quite walkable and you can discover loads of attractions on foot. In this case, footwear can really make or break your trip, so make sure to pack a comfortable pair for walking around!
6. What to wear in Dublin in May

I get asked what to wear in Dublin in May every few days, and the answer depends on what you’ll be doing. May often feels like the start of summer – longer daylight, milder temperatures, and plenty of dry days, though showers are still common. Here’s how I’d break it down:
- 24 hours in Dublin: If you’re in the city centre, light layers and comfortable walking shoes are fine, but a waterproof jacket is still worth carrying
- 2 days in Dublin: Casual daytime outfits work well, but pack a smarter layer for evenings when it’s cooler or if you’re heading out for dinner
- 3 days in Dublin: With three days you might explore the Dublin Mountains or head out to Howth – sturdy shoes, a fleece for breezier moments, and a light rain jacket will come in handy
