You'll find that crowds drop off as schools return. Settled, warm weather usually lingers on from summer.

All of the tourist attractions are still open. So exploring all those ancient castles and historic houses is still an option.

Ireland's Weather in September

The weather in September in Ireland can be very pleasant. Temperatures range from 13 degrees C / 55 degrees F to lows of 9 degrees C / 48 degree F.

If it does rain, western and northern parts of the island receive the bulk. Most rain falls as showers, punctuated by sunshine. The upside? Seemingly endless days of spectacular rainbows!

Warm Seas

The water temperature can be at its highest in late August/early September. If youre the outdoor sort who enjoys a bit of surfing or kayaking - September could be the perfect month for you.

Feeling brave? Well, a dip in Ireland's oceans is a sure way to invigorate the mind and body for the wonderful day of sights ahead.

Bright Evenings

Ireland is surprisingly far north - we're on the same latitude as Newfoundland in Canada!

This means that bright evenings stretch until 7:30-8:30pm - ideal conditions to catch a stunning sunset as you stretch your legs after dinner!

As we say here, there's no such thing as bad weather, only bad clothes!

Harvest Food and Wild Foraging in Ireland in September

September in Ireland is harvest time. Orchards brim with apples and pears. Gardens and greenhouses are bursting with vegetables.

September is also the best time for wild food foraging. Roadside hedgerows are full of wild edible fare - if you know where to look!

Try blackberries, hazelnuts, edible greens, and mushrooms*. They're all abundant and so good for you.

*Always remember to consult an expert before eating anything wild, particularly mushrooms.

Looking for love? Or just up for some craic?

Lisdoonvarna is Ireland's original matchmaking festival. Running for over 160 years, it's a month of both traditional matchmaking and extremely informal fun.

The Fringe continues to push artistic boundaries in venues across Dublin during mid-September.

There are dozens of shows, art installations and street performances to choose from.

It's a celebration of Ireland's rural, agricultural culture. A quarter of a million people visit a different location each year - in 2019 it's in Carlow.
