Ireland Weather and Seasons for a Campervan Trip

Quick summary: Ireland’s weather is mild, green and famously changeable, and a campervan trip works in any season with the right expectations. Rain can arrive at any time, often followed by sunshine and rainbows within the hour. Summer brings long evenings and busy campsites, spring and autumn bring quieter roads, and winter brings short days, wind, occasional ice and fewer open campsites. Bring rain gear and warm clothing, and keep a few museums or pubs in reserve for wet afternoons in your campervan or motorhome.

What is summer like?

Mild rather than hot, with daylight lasting late into the evening. It’s the busiest time for campsites, the Ring of Kerry and the Cliffs of Moher, so book ahead and start early.

Why consider spring or autumn?

For fewer crowds and lower demand on campsites and campervans, with fresh green landscapes in spring and golden colors in autumn. Some smaller attractions have shorter hours.

Is a winter RV trip a good idea?

It’s possible but more challenging. Days are short, Atlantic storms bring strong winds, and roads can be icy. Many campsites close for the season, so check carefully and choose a well-heated vehicle.

What about St Patrick’s Day?

Dublin and towns across Ireland celebrate with parades and events, making it a busy time for campervans and accommodation. Book early if you’re planning to be there.

What should you pack?

A waterproof jacket and pants, warm layers, walking boots, and a hat and gloves in the cooler months. Bring hiking shoes for coastal walks and cliff paths.
