Peak season
Made up of England, Scotland, Wales and Northern Ireland, travellers planning flights to the United Kingdom could find it hard to choose just one place to visit. The United Kingdom is a year-round flight destination and from north to south, travellers are spoiled for choice with the range of attractions. Peak season for flights to London and the major tourist centres are the summer months (June to August) when temperatures range between 14C and 30C. At this time there are an abundance of events taking place, so be prepared for queues and crowds, especially in London which hosts the City of London Festival, Wimbledon, British Summer Time Hyde Park and many more. Scotland has its own fun in the sun with the Edinburgh Festival running throughout most of August. Christmas and New Year is peak travel time for Brits so be prepared for lots of people on your flight during this period.
Off Season
Winter (December to February) is the off season in the United Kingdom with single digit temperatures and rain, hail, sleet and snow lashing the country. But it’s not all bad news, winter means fewer tourists and more chance of scoring discounted hotel rooms and cheap flights. Although many attractions close for the season, many museums and theatres are in full swing. This is also the best time to visit the United Kingdom for participating in winter sports. Scotland has five main areas for winter sports: Nevis Range, Glencoe, Glenshee, Cairngorm and the Lecht.
