Should you visit Ireland in September?

Absolutely! As a huge fan of low and shoulder season travel, visiting Ireland in September means fewer tourists with pleasant weather, too. I think this is especially helpful in quaint towns like Galway, where heavy tourism makes for a much different experience.

Plus, the prices are much lower than traveling during the summer months, potentially saving you thousands during your trip.

What is also great about visiting Ireland in September is seeing the start of the autumn colors. Bright greens, golds and reds are beginning. This is especially great for scenic drives, like the Ring of Kerry.

All to say that Ireland is a great place to visit in September, just so long as you don’t mind a little rain here and there.

Ireland weather in September

Ireland’s weather in September is quite volatile. You’ll see temperatures fluctuate between the high-50s (sometimes even the mid-60s) to the low-40s. Cold weather is just starting to change the landscape.

It’s also a rainy month, seeing between 10-20 days of rain in September. Keep in mind, however, much of the rain will be lighter and just an annoyance during a portion of your day. But you might also see periods of heavier rain, too.

More than anything just know it’ll be colder, a bit dreary, and totally unpredictable. But having traveled to Ireland in September with it raining most days, I didn’t feel like the rain impacted my overall experience. Honestly, just having proper attire makes all the difference.

Thoughts on packing for Ireland

Because the weather can be totally unpredictable in September, packing for Ireland in layers and waterproof options is the best way to be comfortable while exploring. Having the right packing strategy is the difference between enjoying your trip or not.

Over the years I’ve found that rain doesn’t really have an effect on my trips as long as I’ve got the right gear. On my own trip to Ireland it rained 4 of the 7 days at least a portion of the day. Two of which it rained all-day.

I found many years ago that investing in the right attire for the unpredictable British Isles is best. After all, all Europeans have a proper rain jacket… so maybe you should too!

All to say that this Ireland packing list is created to help you have the right gear to enjoy your trip. I brought my entire wardrobe in a carry-on for a weeklong trip but feel free to adapt this to fit your preferences!

What to pack for Ireland in September (complete list)

Don’t let other travel guides fool you – packing for Ireland (and really any international trip) is quite simple. Packing basics that work with anything and considering layers for a variety of weather conditions will make for an easier packing experience.

What to pack for Ireland in September is easier than it might seem. And I hope this guide will make it so for you, too!

Sweaters and Cardigans

Having sweaters for a base layer, especially on colder days, will help keep you warm throughout your daily activities. And since many of Ireland’s best things to do are outdoors, you’ll certainly want to keep warm. I like to bring merino wool sweaters since they are moisture-wicking and thermal-regulating. Plus, they are naturally anti-bacterial, so you can wear them many times before having to wash without your sweater smelling.

What I’d bring: 2-3 sweaters

Long and short sleeve tops

When packing for Ireland in September layering is so important. Primarily because each day will look a bit different. I recommend bringing at least one long and short sleeve shirt for those days where it gets a little hotter and a sweater is too much. I’m a huge fan of merino wool t-shirts since they won’t smell after a day wearing them. It allows you to pack less while still feeling fresh!

What I’d bring: 1-2 long sleeve and 1-2 short sleeve shirts

Fall “shaket”

I’m obsessed with this flannel shaket I brought on my trip. It was the perfect layer for milder days and felt like it fit the colors and vibe of Ireland, too. Having something like this lets you continue to have a variety of layers for the trip so you’re always comfortable outside. Plus, as an added benefit it packs small in your luggage.

Jeans

Ireland’s weather in September is perfect for your favorite pair of jeans. Oliver Logan makes my favorite jeans (I’m especially obsessed with the Aberdeen cut). If you happen to get cold easily try layering your jeans with some lightweight thermals underneath your jeans.

What I’d bring: 1-2 pairs of jeans

Waterproof rain jacket

Do not leave for Ireland without a legit waterproof rain jacket (I like this one!). Since many activities are outdoors in Ireland, you’ll want to ensure your jacket is waterproof and not just water resistant. There is nothing worse than being outside cold and wet – avoid it!

Lightweight down jacket

Even though you’ll have a rain jacket, you’ll still likely want another layer for warmth on the colder days. (Plus, depending on the weather each day the rain jacket might not be necessary.) Down jackets are certainly an investment, but they pack small and are perfect for every trip you take.

On my trip to Ireland I also brought my Kavu Zaltana jacket - primarily because I couldn't decide on which one I wanted. I loved having both to give my wardrobe a bit of versatility. But just so long as you have a warmer jacket that's perfect for a crisp fall day you'll be fine!

Chelsea boots

I love bringing a pair of waterproof Chelsea boots to Ireland. These will keep you dry on even the wettest day! I love Chelsea boots because they are so versatile, too. They are perfect for easy hikes, walking around town, and excursions. Plus, you’ll find that they are super helpful for so many trips after Ireland! I wear mine on pretty much any trip where it’s a high chance of rain.

Sneakers

Sneakers are perfect around Dublin but also on days in the countryside without rain. I have been wearing Allbirds for years now as my go-to walking shoes. They are made of merino wool, so no stinky shoes in your luggage! I also find them super comfortable on travel days – from airports to flights they are the best.

Beanie Hat

We had a few colder days at the beginning of our trip and I’m so glad I brought my beanie. I didn’t wear it much but it did come in handy on a few occasions, especially in the mornings and evenings. It’s so easy to add to your suitcase that it’s a no-brainer to make this a just in case addition for your packing list.

Warm pajamas

At night and around your hotel you’ll want a pair of pajamas that are warm to wear in bed. I love investing in a cozy set that you can easily wear around your hotel room. Most hotels in Ireland include radiator heat, which is efficient but doesn’t heat the space as well as other systems – so warm PJs are a must!

Umbrella

Personally, I prefer to just have a good rain jacket and forgo the umbrella. However, if you like to feel really dry consider bringing a lightweight, small umbrella to have around. It’s easy enough to add to the backseat of you rental car if you plan on a road trip for those unfortunate changes in weather during the day.

Water bottle

You can drink the water right from the tap in Ireland, so bringing a water bottle will save you money during your trip. I’ve been bringing a Hydroflask with me on every trip for the past eight years! It’s great because it keeps your water cold during the day and fits into any cup holder or backpack with ease.

UK power adapter 

Ireland uses a UK plug system, so a power adapter will be required when traveling. I recommend a universal power adapter, which will give you access to power anywhere in the world in one device. You could also opt for adapters that work for US to UK systems instead of a universal one.

Wash bag

I bring my Scrubba bag on every trip. It’s perfect for washing a few items here and there with some laundry sheets. (I use these!) Though you might not need this for a shorter trip to Ireland, I always find myself using my Scrubba on trips longer than 9 days.

No foreign transaction fee travel credit card

Ireland is a card-heavy country and utilizing a credit card without foreign transaction fees will save you a lot of money. Travel cards, like the Capital One Venture, are perfect for travel because you’ll remove the additional fees while also earning you points towards future trips!

Travel Tip! When asked if you want to pay in US dollars or Euros always select the Euro. Your bank will do a better job at converting currencies, saving you a lot of money!

eSIM

I love the Airalo app to get an eSim around the world. eSims are the best way to stay connected at top speeds on your phone when traveling. But if you need basic internet on your trip some phone companies, like t-Mobile have 3G in most countries for free.

My must-have airplane packing list

After traveling over 100 days a year for some time now I’ve got my day-of packing down to a science. Here’s my set up for my flight to Europe (or anywhere else in the world). Plus, some secret travel tips to help you become a better packer, too!

My go-to travel day outfit

Shirt | Basic cotton t-shirt
Pants | Eddie Bauer Departure joggers
Sweatshirt | Performance hoodie
Backpack | Nordace
Shoes | Allbirds Wool Runners
Luggage | Away Carry-On

Don’t leave home without these

  • Passport and ID | You’ll need your driver’s license if you plan to rent a car and your passport to get into Ireland. Passport holders with Airtags are becoming popular options to ensure you never lose your passport again, too
  • Phone | I don’t think anyone leaves home without their phone anymore but be sure that it’s fully charged with all your favorite podcasts downloaded
  • Wallet with travel credit card | I like to bring 2 travel cards and my debit card when I travel. Having an extra travel card is necessary just in case your card doesn’t want to work at a hotel or rental car desk
  • Portable charger | The Anker power bank is the best (I’ve been using it for years)

Entertainment

  • Noise cancelling headphones | Never listen to a crying baby again with the best pair of headphones. I have the Bose QuietComfort and have loved them for years
  • AirFly Pro | Pairing this with the headrest monitor lets you watch the TVs movies and shows while continuing to be cord-free

Long-Haul comfort

  • Eye mask | Invest in a quality eye mask that blocks out all the light – you’ll thank me later
  • Trtl pillow | Travel pillows are generally silly – they are bulky and you have to take them around your entire trip! The Trtl pillow is the only one I recommend (and have actually gotten good sleep using)
  • Medications | Never add these to your luggage – keep them in your carry-on. I like to add some of these sleep tablets from Olly if I have an overnight
  • Toothbrush and toothpaste | Even if you’re not a teeth brusher on the plane (I’m not) it’s a good idea to pack this in your carry-on so you can use it upon arrival to Ireland

Other essentials

  • Travel blanket | If you’ve ever traveled in economy you know it’s cold. And at least for me those dinky blankets just don’t cut it. Invest in a quality travel blanket and actually sleep on the overnight flights
  • Pen | Though you don’t need one for entering Ireland, oftentimes traveling requires filling our forms and having a pen on hand is a great idea

Ireland packing + travel tips

  • Think of your clothes as a capsule wardrobe, where everything goes together, and you’ll be able to pack a lot less. I like to pack neutrals and solids and try to bring as much cotton, linen, and wool as possible.
  • If you plan to rent a car remember that economy car rentals are much smaller than the US versions. If you have a lot of luggage you might need to upgrade your car to a larger one to ensure everything (and everyone) fits.
  • Check the weather for your trip about a week prior to finalize your packing list but the weather can change within 24 hours, so don’t trust it if it says you’ll have sun all week either.
