One of the most popular questions on Google is “When is the best time to visit Ireland?” Whether you're planning a trip to Ireland, coming home for a visit or just wanting to explore outside your door, in 3 minutes or less we want to help answer that question.

So let's start at the beginning.

When Does Autumn Start in Ireland?

It may not feel like it every day, but once September hit, autumn in Ireland began, and we’re into a season full of rich colours and cooler weather. but what marks its official beginning is the autumn equinox. This year, the autumnal equinox takes place on Sunday, September 22nd, at 1:43 pm. Autumn in Ireland is September, October and November.

During this event, the sun moves directly above the equator, aligning with the celestial equator, as it heads south. This alignment creates a rare moment when day and night are of equal length. For us, it symbolizes the shift into shorter days and longer nights—a gentle reminder to embrace the warmth of cosy evenings.

As we transition from the brightness of summer to the golden glow of autumn, there’s something magical in the air—nature starts to slow down and we get to enjoy the earthy tones and cooler temperatures that make this season so special.

Will Autumn Be Cold This Year?

Would you believe this is one of the most asked questions about autumn in Ireland. If you’re a regular in Irish weather conversations, you know predicting the weather here is almost impossible. Early autumn, particularly in September, can be mild, with occasional sunny spells that make it perfect for outdoor activities. 

But there’s something about that September sun when the sky is a pastel palette of blue, pink, orange and purple. By October and November, you’ll start to feel the bite of colder winds and crisper mornings. Regardless, it’s nothing our Wicklow Hills 100% organic cotton hoodie can't handle.
