Would I visit Ireland in May: A no-BS answer

I would absolutely visit Ireland in May.

My birthday falls at the beginning of May, so I tend to head away for a couple of nights on the weekend that follows it.

I’ve been to Cork, Mayo, Antrim, and Galway in May over the past 4 years, and had great weather each and every time. 

Last year, when we visited Cork, a couple of us got sunburn on a walk around the Old Head of Kinsale. 

What I love about May in Ireland:

  • The weather tends to be OK (but rain is always a possibility)
  • The days are nice and long (sunrise is ar around 05:15 and sunset is around 09:15 in the middle of the month)
  • Crowds have yet to reach summer peak

If you read our guide to Ireland in October, you’ll have heard me say this already.

What you pack for Ireland in May will depend hugely on the type of holiday you have planned.

Those visiting for an active holiday

If you’re visiting Ireland for an active holiday where you’ll be exploring on foot or by bike, you’ll need:

  • Some decent hiking/walking footwear
  • A light waterproof jacket
  • Waterproof trousers
  • Appropriate layers that you can remove or put on if it gets too hot/cold

Those visiting on a city break

If you’re just planning on sauntering around one of Ireland’s cities for a few days, bring:

  • Layers (again, I know)
  • A light waterproof jacket
  • Casual clothes for evening wear (shirt/polo-shirt and jeans/chinos are all appropriate ‘going-out wear’ in Ireland)
