Ireland's weather is famously unpredictable. "Four seasons in one day" isn't just a saying—it's genuine advice for packing. This guide ensures you're prepared for whatever the Irish skies deliver.
Ireland's Climate Reality
Key Facts
- Average rainy days: 225 per year (more in the west)
- Summer temperatures: 15-20°C (rarely above 25°C)
- Winter temperatures: 4-8°C (rarely below freezing at coast)
- Humidity: High year-round

The Golden Rule
Layer everything. You'll add and remove layers constantly throughout the day.
