Winter Season

• Time Period: December to February

• Average Rainfall: 130 to 350 mm 

It rains a lot during this season, and the temperatures are usually quite low. As a result, most days in Ireland are quite gloomy and wet throughout the three months of winter. As a result, visitors will not be able to enjoy outdoor activities. 

Visitors who travel to Ireland during this time tend to carry umbrellas and raincoats with warm trench coats and jackets. Furthermore, only a few high-altitude areas in Ireland get the chance to witness snowfall. 

This is also the low season in Ireland. As a result, fewer international travellers come to this country to spend their vacation. This is also the reason why the accommodations are the cheapest.

Winter is the best season for you if you wish to travel to Ireland from India with budget-friendly travel packages. Even though the temperature and daily weather are quite harsh in Ireland during the winters, you will easily find great accommodations at low prices. 

Furthermore, if you desire to stay at a castle, you can enter luxury castles at prices lower than usual by 200 euros. Ireland's best places to visit during winters are its Christmas night markets and museums.

You may not be able to experience Ireland's natural beauty and wildlife during winter, but you will have a lot of options for indoor activities. You can visit a cosy pub, have a few beers, and chat with locals. We also suggest you spend your Christmas in Dublin if you visit Ireland around that time as you will not want to miss the celebrations.

Below are certain things that you must know before visiting Ireland. These will come in handy while you are on vacation in this European country:

• Big cities like Belfast and Dublin will have a lot to offer you in terms of visiting museums and pubs. However, Ireland's small towns and villages have a charm of their own. So, make sure to include the villages and towns in your travel plan.
• In Ireland, restaurants and pubs do not serve food all day long. For instance, a restaurant is open after lunch but will only serve you drinks and no food during this time. So plan your meals beforehand and then plan your travel for the day. 
• There is no tipping system at restaurants in Ireland. So make sure you do not tip the servers. 
• Consider renting a car if you want to explore the country via road. 
• Northern Ireland and Ireland are very different from each in terms of geography and currency. You must always remember that Northern Ireland is still a part of the United Kingdom and Ireland is an independent country.
