Ireland's currency is the Euro. Shops, restaurants etcetera will not accept any other currency. However, you can use credit or debit cards pretty much anywhere. You can also withdraw Euro banknotes from ATMs using your debit or credit card. Exchanging foreign currency banknotes for Euros in a bank for FX centre can be expensive.
The weather in Dublin can be changeable and unpredictable. No matter what season you visit in, 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 more or less what you can expect: WINTER months - 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 months - somewhat warmer with temperatures ranging from around 4-14C / 39-57F. Roughly 30% chance of rain on any given day. SUMMER months - 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.

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.. Most likely you will 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. It can be dangerous to use an electrical appliance that is rated at a different voltage to the supply. You'll know whether you need a converter by checking 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.
