Off-peak Season:
If you’re not a sun worshipper, then you’ll have no problem coming here in the off season. Booking a cheap flight to Cardiff in the winter (December to February) will undoubtedly afford you with rainy days and cold temperatures, but one thing is certain – the beauty and culture of this city never dies down, even when the good weather does.
Like the rest of the United Kingdom, Cardiff is no stranger to seasonal climate and inclement, unpredictable weather. To stay on the safe side, expect the unexpected when you book flights to Cardiff. Winters are wet, and temperatures crawl down to negative temperatures, so pack warm clothing and always an umbrella – no matter what time of year. Summers (June to August) on the other hand, are known to bring sunny days (between the rainy ones) and temperatures in the mid-20s. Rain and wind roll in during springtime (March to May), but the mild May weather and pretty, delicate flowers make up for the occasional shower.
Why visit the city?

Visiting the city there’s no way in getting around its beautiful Cardiff Castle, its neoclassic Civic Center, and the illustrious Cardiff Bay, where the waterfront has become a well-developed centre for people to meet and gather on sunny afternoons in the summertime.
Take a cheap flight to Cardiff and find yourself with plenty to do, between museums, art galleries, restaurants, nightlife, and natural history but there are also options for those visitors who instead seek places of solitude away from urban chaos. Green space, gardens, and esplanades are all over the place, allowing you to make the choice between bustling city life, and a peaceful walk in the park.
