In the summer, from early May until late August, the city of Dublin can get very warm, and therefore light cotton clothing is sensible. There is less rain during the summer months, but Ireland has a very wet climate with changeable weather. It is not unusual for a sunny day to quickly cloud over and turn into a rainy day. Temperatures during the Summer can reach easily to 20°C on most days and occasionally reach up to 25° on hot days in July.

Winters in Dublin can be both long and damp, so be sure to bring a thick overcoat or jacket, gloves and scarf. Snow is infrequent, but there are often cold, clear, frosty days.

If you are planning to visit outdoor locations in Dublin, water-resistant shoes are always recommended as the city's pavements can often become extremely wet after heavy rain, and an umbrella is a must. Temperatures during the Winter can reach to just 3°C but don't go below freezing that often except from January. On most days the temperatures stay around 5-12°C. 

The best time to visit Dublin, ranges from April to October, taking away July and August is you want to avoid the high season.

Dublin has a bustling young nightlife and its people are known for their love of all things that involve drinking, the Irish take their pubs and pints very seriously and it's little wonder traditional old pubs and bars dominate the nightlife scene.

The Temple Bar district is the hub of Dublin's nightlife scene and by far the most popular place to start. Visitors will find around 24 bars and 73 cafes and restaurants to choose from.

The Grafton Street side of things provides a much quieter and more relaxed alternative to the chaos of Temple Bar, attracting a different type of crowd. Wine bars are also becoming a popular addition to the entertainment scene, providing patrons with a wine list and reasonably priced meals. 

🌈The gay scene in Dublin is taking off too and there are many gay clubs and bars springing up everywhere. Most pubs and bars close early, around 11pm, but some have official permission to stay open late.

On just about every night, visitors can enjoy rock, jazz, blues and traditional Irish folk concerts at theatres, sports stadiums, churches, clubs and castles.

Dublin may be small, with its two main shopping districts located no more than a 20 minute walk away from each other.

The largest of Dublin's shopping venues is the Jervis Shopping Centre. Located on the north side of the River Liffey, it offers two floors of shopping decadence, while the top floor is a food hall, where shoppers can stop to refuel. The Blanchardstown Centre spans two floors, four wings and a plethora of shops and boutiques that sell just about everything.

On the south side of the river is Grafton Street, where some of Dublin's most expensive shops can be found. The Blackrock Market is popular with tourists looking for locally produced arts, crafts and food. The Temple Bar district also has several markets for books and locally-produced foodstuffs. The House of Ireland on Nassau Street is the place to go to buy some of the finest quality souvenirs Ireland has to offer, from crystal to knitwear and Irish linen, which is still regarded as some of the best in the world. Other popular Dublin souvenirs are the cheap tin-whistles found in many shops.

The city has plenty of entertainment to offer and specially at the weekends it's popular for visitors to fill the streets up, staying in Dublin city centre can be expensive, (€130 per night) so going a little out of the city can be the trick to grab a reasonable Hotel and then pay a little more to get into the city to visit. With the added benefit of exploring more of the city and also being quieter areas out of the centre. (Prices can then be about €60) Bed & Breakfasts are very popular as well as Hostels for those on tight budgets. Also Airbnb is becoming a good option for private accommodation or shared houses. Staying during the week and in the lower season will be much cheaper. 

Visiting Dublin won't take long, normally visitors go on a long weekend to enjoy the nightlife. It's easy to walk around on foot do the main landmarks of the city and cultural/historical buildings. Depending what's your preference, but 3 nights should be enough.
