Planning a summer trip to Ireland? Knowing what to wear in Ireland in summer is essential for a comfortable and enjoyable stay. While June, July, and August offer the warmest months of the year, Ireland's climate remains famously unpredictable.

This comprehensive guide covers everything you need to know about dressing for an Irish summer, including detailed packing lists, temperature expectations, and top tips to help you blend comfort, practicality, and style!

Ireland’s Summer Weather: What to Expect

Although summer in Ireland is the warmest season, it is not hot by international standards. The weather is mild, changeable, and often damp, with cool breezes and light showers even on sunny days.

Average Summer Temperatures in Ireland:

• June: 11°C to 18°C (52°F to 64°F)
• July: 13°C to 20°C (55°F to 68°F)
• August: 13°C to 19°C (55°F to 66°F)

Weather Patterns to Be Aware Of:

• Sunshine: Up to 16–18 hours of daylight with occasional bursts of strong sun.
• Rain: Light, scattered showers are common, even during clear days.
• Wind: Breezy along the coasts and in higher altitudes.
• Humidity: Generally moderate, adding to the coolness of damp days.

In short, expect variety. A single day may include mist, sun, wind, and rain.

Essential Summer Clothing for Ireland

When it comes to what to wear in Ireland in summer, think versatile, breathable layers that keep you warm when needed but are easy to remove during warmer spells.

1. Lightweight Waterproof Jacket

A high-quality, waterproof and windproof jacket is non-negotiable. Preferably hooded and packable, it should be breathable enough for warm spells while protecting you from sudden showers and coastal winds.

Recommended features:

• Waterproof (not just water-resistant)
• Windproof
• Breathable fabric (e.g., Gore-Tex)
• Adjustable hood and cuffs

2. Layered Tops

Layering is crucial. Pack a mix of:

• Moisture-wicking T-shirts
• Long-sleeve tops or lightweight sweaters
• Light fleece or thermal tops for cooler evenings

Materials like merino wool or performance blends are ideal for temperature regulation.

3. Comfortable Bottoms

• Jeans: Durable and casual, but bring just one pair as they take time to dry
• Travel pants: Quick-drying, lightweight, and comfortable for hikes or city tours
• Leggings or joggers: Perfect for relaxed days or flights

Avoid shorts unless you’re used to cool summer breezes—they're rarely needed.

4. Practical Footwear

Your shoes must be comfortable, waterproof, and suitable for walking. Ireland’s stunning scenery often requires exploring uneven, sometimes muddy terrain.

• Waterproof walking shoes or boots
• Sturdy sneakers or trail runners
• Slip-on flats or sandals (for evenings or city wear only)

5. Weather-Adaptable Accessories

• Umbrella: A compact, wind-resistant one
• Scarf: Lightweight but adds warmth if temps drop
• Sunglasses: UV protection for long daylight hours
• Daypack: Water-resistant for day trips and tours

Special Considerations for Exploring Ireland in Summer

Urban vs. Rural Packing

If your itinerary includes both Dublin city strolls and Connemara hikes, dress accordingly. Cities call for smart-casual layers and clean footwear. The countryside demands durability, weather protection, and comfort.

Cultural Norms and Modesty

Irish dress tends to be casual and modest. Revealing summer clothing like short shorts or crop tops is uncommon, especially in rural or religious settings. Layers are not only practical—they’re culturally appropriate.

Activities & Outdoor Adventures

Planning to surf in Lahinch or trek the Cliffs of Moher? Be sure to include:

• Waterproof hiking gear
• Quick-dry athletic wear
• A swimsuit (but don't expect tropical water temps)

Bonus Tips: Packing for Ireland’s Summer Like a Pro

• Bring a power adapter: Ireland uses the Type G plug (same as the UK)
• Pack for carry-on only if possible: Saves time and reduces luggage stress
• Use packing cubes: For neat, weather-based outfit organization
• Choose wrinkle-resistant fabrics: For effortless transitions between rural tours and pub nights
• Dry bags: Handy for electronics and valuables on rainy days
