While there may be occasional rainfall, it mostly happens in the north and west, often in the form of showers. Typically, periods of sunshine follow these showers.

Visiting Ireland in September has several advantages. The weather is generally stable, allowing you to explore and appreciate the country’s beauty without extreme heat or cold. There are also many things to do in Ireland in the fall that you’ll love.

The warm sea temperatures and slightly longer daylight hours add to the overall appeal. Additionally, visiting in September means you’ll find fewer crowds than you would while traveling to Ireland in July or other busy summer months. 

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!

By following these packing tips, you’ll be prepared for the weather and able to enjoy your trip to Ireland comfortably.
