Table of Contents
The island of Ireland in the Atlantic Ocean is divided into Northern Ireland (around 16%) and the larger Republic of Ireland in the southern area (around 84% of the island area).
Northern Ireland is more densely populated than its independent”neighbour” and part of the Kingdom of Great Britain and Northern Ireland. More than 1.7 million inhabitants live on an area of around 8600 square miles.
The capital of Northern Ireland is Belfast, which is also connected to the Irish capital Dublin via the island’s main motorway. Due to the Common Travel Area Agreement there are no border controls between the two countries.
Slieve Donard is the highest peak in the country at 849 metres. The largest lake in the British Isles is located in central Northern Ireland, Lough Neagh. The coastline has a length of about 310 miles, the widest extent from east to west is 110 miles.

Like all British Isles, Northern Ireland has an oceanic climate, which can be described as moderate maritime due to the effects of the Gulf Stream. Despite its northern location, the climate is therefore quite mild (and humid) in winter, while the summers are somewhat cooler than in other regions on this longitude. There are rains all year round in Northern Ireland, especially in autumn and winter.
In the highlands there is about 62.99 in of precipitation per year. In the northwest around Londonderry, almost 0.08 in of rain fall each year. Dryer areas are located in the south and east of the coastal areas near Lough Neagh with only about 31.5 in of rain per year. In the areas above 850 metres there is snowfall on an average of 35 days a year.
The warmest temperatures are in the summer months of June, July and August. On average a daytime temperature of 18 °C to 19 °C is reached in these months, while night temperatures of around 10 °C are usual in summer. The number of hours of sunshine is quite low all year round, only Scotland has even less sunshine in the region. In winter it is not very cold, even in January the average is 3.9 °C.

When to go to Northern Ireland?
The best time to visit Northern Ireland is from May to September. The days are longest in this time and the temperatures are comparatively pleasant. Statistically, May has the most hours of sunshine in the year and is therefore an ideal month for round trips. The east of Northern Ireland is weather-technically the whole year round more constant and usually also sunnier than the west coast.
The warmest months are July and August, while from November to March it can be noticeably fresher in Northern Ireland. Especially the steady wind often makes the temperatures seem colder than they actually are. Basically, the British Isles are good and safe to travel all year round. When considering the best travel season in Northern Ireland, however, we deliberately recommend the months with the best weather conditions.
