What to Pack for Ireland in September
Here’s an essential packing list for visiting during September in Ireland:
- Bring a small amount of summer/light clothes. You will probably only get to wear them once or twice during your trip.
- The trick to staying warm is to have many layers that you can put on and take off to adjust your temperature.
- Wear long sleeves and long pants. It won’t be freezing, but the wind can get cold.
- Rain boots would be great if you are hiking or exploring farms and fields. A pair of hiking boots will also do the trick if they are too bulky.
- Pack a very light raincoat. It rains a lot in Ireland, but that doesn’t mean it’s cold.
- Consider bringing a shawl. It is super compact and can do the trick on some occasions.
- Bring one warm hoodie for the evenings.
- A reliable pair of jeans is a good call. You won’t be too sweaty in them; they are very durable.
- Overall, you won’t need any heavy-duty winter clothing, but you should definitely make sure to have items that block wind and protect against rain, as September is known for being one of the rainiest months!
