Ireland's currency is the Euro. Shops, restaurants etcetera won't accept any other currency, but you can use credit or debit cards everywhere. You can also withdraw Euro banknotes from ATMs using your debit or credit card.
Dublin's weather can be changeable and unpredictable - so hope for the best but prepare for the worst! That means a hat and gloves in Spring and a rain jacket in Summer. Generally it's cool and humid all year round, but this is roughly what to expect: WINTER - typically cold and often wet. Temperatures range from 3-9C / 36-47F but wind and humidity can make it feel colder. Around 40% likelihood of raining on any one particular day. SPRING - somewhat warmer with temperatures ranging from around 4-14C / 39-57F. Roughly 30% chance of rain on any given day. SUMMER - warmer but rarely ‘hot’ with temperatures ranging 10-20C / 50-68F. On average, it rains 10 days per month during summer months. The highest ever recorded summer temperature in Dublin was 33C/92F but this is very unusual. AUTUMN - generally cloudy and gets progressively colder: average temperature in September is 13C/55F but 7C/45F in November. It rains on average 12 days per month in Autumn.
There are times throughout the year when Dublin is transformed with a surge in energy or festive or celebratory spirit! These are great times to visit - but tend to be much busier and more expensive too. The main festivals and holidays in 2025 are: Dublin International Film Festival, February 20-March 2, 2025; St Patricks Festival, March 15-18, 2025; Easter, April 18-21, 2025; Pride, June 28, 2025; Christmas, December 24-26, 2025; and New Years Eve, December 31, 2025.

Ireland (like the UK) uses Type G electrical sockets and plugs [these are the ones with three rectangular pins in a triangular pattern] and operates on a 230V supply voltage and 50Hz. You'll certainly need a travel adaptor, which just allows you to plug any electrical appliance into an Irish electrical socket. However, these devices do not generally convert the voltage or frequency, so you may need a voltage converter or transformer too. To find out if you need a converter, check the 'rating plate' on your electrical appliance. Some appliances are 'dual voltage rated' and can operate within a voltage range. For example, you might see ‘INPUT: 110-240V’ on the label on the appliance or its power supply. This means there is no need for a converter/transformer as Ireland operates on a 230V supply voltage, which is within the appliance's 110-240V range. However, some appliances are 'single voltage rated' and you will need a converter or transformer. This is most often the case with hairdryers and hair straighteners.
