It's wet, it's miserable and the Christmas decorations have been taken down so there is only one thing for it! Get booking a summer holiday.

Nearly one million people are people are set to visit a TUI shop or the TUI website on Saturday, January 6, coined as 'Sunshine Saturday', as they search for their annual holiday.

It is predicted to be the busiest day of the year for holiday bookings according to the UK's largest holiday brand, based on booking figures over the past five years.

Get ready for Sunshine Saturday!

Turkey, Montenegro, Halkidiki, Croatia and Cape Verde are expected to prove popular this year with the predicted rise in the mid haul holiday.

Holidaymakers are also seeking new and exciting destinations when booking beach holidays with some shunning traditional seven and 14-night breaks in favour of 10 and 11-night holidays, which are expected to become the new normal.

TUI holiday advisors helped most customers find their perfect holiday between 11am and 1pm last year.

Holiday bookings in store peaked at noon with Canaries favourites Tenerife, Palma and Lanzarote topping the list as the top three destinations.

For customers looking to travel further afield, Goa, Costa Rica and Vietnam are expected to be in high demand for 2018.

Sunseekers who are looking to experience more during their annual holiday have helped see the rise of multi-centre holiday bookings this year.

Explore Asia with Marella Cruises

Cruise fans will also have even more choice as Marella Explorer offers exotic new routes including Asia for 2018.

From the tranquil white sands of Koh Samui, Thailand to the mystical jungles of Costa Rica there is a collection of itineraries and deals to cater to everyone's tastes.

Richard Sofer, commercial director for TUI UK and Ireland said: "Over the last few years we've seen an early booking trend for summer holidays and this week we expect this trend to continue with our busiest booking day of year taking place on Saturday.

"This year we expect to see Brits returning to classic mid-haul favourites such as Turkey and exploring new destinations such as European hotspot Montenegro, which is set to be the new mid-haul gem, as people look for holidays that offer more than just a week on the beach."

Last summer alone, TUI Airways spent more than 41,000 hours in the air jetting millions of holidaymakers away to sunny climates which equates to flying around the world more than a whopping 600 times.
