Dublin’s weather is famously unpredictable. The saying “four seasons in one day” is genuinely accurate. Rain is frequent but rarely heavy — it tends to be light showers that come and go.
Temperature
Temperatures range from around 5°C in winter to 20°C in summer. It rarely gets extremely hot or bitterly cold, but the damp can make it feel colder than the numbers suggest. Layering is the key to staying comfortable.
What to Pack
- A waterproof jacket (essential, not optional)
- Layers: t-shirt, jumper, light jacket
- Comfortable walking shoes — Dublin’s cobbled streets aren’t friendly to heels
- A compact umbrella
- Sunglasses — yes, the sun does come out
Best Months for Weather
May to September offers the warmest weather and longest days. In June the sun doesn’t set until after 10pm, giving you incredibly long evenings. July and August are the warmest months, averaging 15–20°C.
Winter
It rarely snows in Dublin, but winter is cold, dark, and damp. In December, the sun sets around 4pm. That said, winter has its charm — cosy pubs, Christmas markets, and far fewer tourists.
