Sydney, Australia
If you want to dust away the cobwebs, blow the budget and annihilate that leftover annual leave in one swoop, Sydney's your best bet. You'll want to spend a few days on the beach, so try Bondi if you can take the crowds, or explore the wilderness of Ku-ring-gai National Park in a kayak if you really want to get away from it all.

Rio de Janeiro, Brazil
When we hunker down here in the UK, the beaches of Brazil hot up, meaning November through February is the best part of the year to hit the Copacabana (or an hour down the road to the quieter, western beaches of Prainha and Grumari if you’re into surfing and extra space) for a spot of frescobol and chill. Alternatively, check out the street art or indulge in huge, cheap cocktails and get your knees up.

Cape Town, South Africa
Winter in South Africa isn’t about scorching highs and , but with temperatures still in the balmy twenties, it’s a great alternative to the brisk streets of London. What’s more, it’s the best time of year to take to the water in search of whales and sharks (if you’re feeling brave), and the top-rate art scene never stops.

Burgers, bikinis, beaches – Miami is the good-time city when you go Stateside in winter, and that's why you should hit it up, stat.

Essaouira, Morocco
Famous for its year-round balminess, the ancient city and windsurfing mecca of Essaouira sits right on the Atlantic coast of Morocco.
