Autumn In Ireland: Weather, Average Temperature + Things To Do

Autumn In Ireland: Weather, Average Temperature + Things To Do

Autumn in Ireland is my favourite time of the year to travel around.

Autumn includes the months of September, October and November and the weather gets more wintery the closer it gets to December.

And, while the days are shorter and cooler, it’s a lovely time to explore Ireland, with many places covered in a blanket of golden leaves at the beginning of the season.

In the guide below, you’ll find everything from average temperatures and what to expect to things to do in Ireland in fall.

Although spending fall in Ireland is fairly straightforward, there are a few need-to-knows that’ll get you up-to-speed on what to expect quickly.

1. When is it

Autumn in Ireland begins at the start of September and runs until the end of November. 

2. The weather

Fall weather in Ireland varies a lot from year to year. In September in Ireland we have average highs of 13°C and lows of 9°C. In Ireland in October we get average highs of 13°C and lows around 6°C. In Ireland in November we get average highs of 11°C and lows of 6.2°C.

 

3. The season

Fall in Ireland is part ‘shoulder season’ (September and October), i.e. the time between peak season and the off season and part off season (November).

4. Shortening days

The days start to shorten rapidly during autumn in Ireland. In September, the sun rises from 06:41 and it sets at 20:14. In October, the sun rises from 07:33 and sets at 19:09. In November, the sun rises from 07:29 and it sets at 17:00. This makes planning your Ireland itinerary towards the end of the season a little bit trickier.

5. Plenty to do

There’s endless things to do in Ireland in the fall, from hikes and walks to scenic drives, tours and much much more (you’ll find suggestions below).

The pros and cons of visiting Ireland in the fall

If you read our guide to the best time to visit Ireland, you’ll know that every single month comes with its advantages and disadvantages.

Below, you’ll find pros and cons to visiting Ireland in the fall, from someone that’s spent 32 years here:

The pros 

  • Weather: Autumn in Ireland tends to be a nice time to travel. Last year, the avg. temperature during fall in Ireland was a mild 11.9 °C
  • September: This is the shoulder season – flight and accommodation prices are lower and the busy peak season has ended. The days are also nice and long (sun rises from 06:41 and it sets at 20:14)
  • October: The air is cool and crisp, there’s golden leaves everywhere (in October) and many popular tourist attractions are much quieter. The days still have a bit of length in them (sun rises from 07:33 and sets at 19:09)
  • November: Many Christmas markets in Ireland kick off during the middle of the month, bringing a buzzy festive atmosphere with them

The cons

  • September: There’s very few. In fact, I can’t think of any off-hand
  • October: The weather is very unpredictable. In October 2017, for example, Storm Ophelia hit Ireland, and it was the worst to hit the island in 50 years
  • November: Again, the weather – the last two Novembers have been mild, but we’ve had freak storms in years past
