January in the UK has a particular mood. The sky sits low. The pavements stay damp even when it hasn’t rained. Your coat smells faintly of yesterday’s bus, and the thought of another grey commute can feel like a personal insult. So you start doing the same thing everyone does. You check the weather somewhere else. You picture bare ankles. A cold drink that sweats down the glass.

That first warm hit on your face when you step out of the airport and think, right, this is better. Here’s the thing, though. “Hot in January” doesn’t mean one thing. Some places are properly tropical, where you’ll want shade by lunchtime. Others are warm in a way that lets you walk around all day without turning into a crisp. And a few are warm but with a bit of wind, which, honestly, can be a gift.

This list is for that moment when you want heat, but you also want the trip to make sense. Not just temperature charts, but the entire feel, the pace, and the little details that matter in January, like whether the sea’s decent, whether it’s a soggy month, and whether you’ll spend your holiday hiding from a downpour.

I’m sticking to places that are reliably warm based on long-term climate averages and mainstream UK travel coverage, not hopeful guesses. For example, the Met Office puts Phuket’s average daily maximum at about 32°C in January. That’s not “maybe shorts”. That’s “Why did I pack jeans?” And yes, the keyword’s in here because you asked: hottest places to visit in January. You’ll see it again, naturally.

Phuket, Thailand

Phuket in January is classic dry season stuff. Bright days, warm water, and evenings where you can sit outside without thinking about it. The Met Office’s holiday climate averages show a January daily max around 32°C, with far less rain than later in the year. If you’re the type who gets bored lying still, this is a good one. Island trips. Snorkelling. Night markets that smell like grilled seafood and sweet chilli. And if you just want to flop, you can do that too.

The Gambia

The Gambia is one of those places that surprises people because the flight time isn’t brutal, but the warmth feels properly real. It’s a straight swap from grey drizzle to sun and sandy air. It’s also an easy one in practical terms, because UK government travel advice confirms British travellers don’t need a visa for a short visit and typically get a 28-day entry stamp on arrival. January suits the vibe. Beach days, river trips, and evenings that cool down just enough to sleep well.

The Maldives

If your idea of a perfect January involves a calm sea and that unreal turquoise, the Maldives does the job. The Met Office climate averages put January around the low 30s for a daily maximum temperature, with plenty of sunshine. It’s not just honeymoon fluff either. You can snorkel straight off many islands, and the water clarity is usually at its best in the drier season. The catch is price. It can sting in January. But if you’re going, this is what the brochures.

Barbados

Barbados in January is the Caribbean at its most likeable. Warm days, lower rainfall than later months, and that trade wind breeze that stops it feeling sticky. UK travel roundups regularly flag January as peak season in the Caribbean, with temperatures hovering around 29°C to 30°C. It’s a good mix, too. You can go to the beach and still have proper evenings out. Rum shops, live music, and a sea that stays inviting.

Dubai, United Arab Emirates

Dubai in January is warm without being punishing, which is exactly why it’s so popular at this time of year. The Met Office and other long-term climate summaries consistently put January daytime highs in the mid-20s. This is the month for doing the outdoors bits you’d avoid in summer. Marina walks. Desert trips. Even just sitting outside with a coffee and not sweating through your shirt in five minutes. It’s heat you can actually use.

Cape Town, South Africa

Cape Town hits January in full summer mode. You get beaches, vineyards, and big sky days where the light feels sharp and clean. It’s also one of those places where you can build a trip around small wins: a morning hike, a lazy lunch, then sea air in the evening. The best part is the variety. If you’re travelling with someone who doesn’t want “just a beach holiday”, Cape Town keeps everyone happy. And the food scene doesn’t mess about.

Costa Rica

Costa Rica in January is a good shout if you want heat but like to go home feeling like you’ve done something. It’s a popular dry season window in many regions, which is why you’ll see it mentioned in winter sun coverage and travel planning for January trips. You can do beaches, yes. But you can also do rainforests, wildlife tours, and that early morning jungle sound that makes you stop talking for a second. Proper perspective, that.

Cape Verde

Cape Verde is one of the easier “winter sun” wins for UK travellers, as it’s warm and relatively near but also quite dry in January. The Met Office’s weather averages for holidays have it averaging a daily maximum of about 25°C in January, with very little rain.  It’s not sauna hot, but it’s shorts and sunglasses weather, and the wind can keep it feeling brisk rather than oppressive. Perfect if you enjoy beach walks, sea views, and not doing an awful lot — guilt-free.

Tenerife, Canary Islands

If you want warmth without the long haul, Tenerife is the reliable mate who turns up on time. The Met Office lists an average January daily maximum of around 21°C. That’s not tropical, but it is a serious upgrade on the UK in January. And it’s the sort of weather where you can hike, do markets, sit outside for lunch, and still pack light. Tip that always holds: the south tends to feel warmer and drier than the north.

Madeira, Portugal

Madeira isn’t the warmest on this list, but it makes a good case for inclusion, as it feels alive in January. There are green hills, ocean views and walking routes that don’t have you melting. It is the kind of warm where you start the day wearing a light jumper and end up stripped down to a T-shirt.

If you’re after the hottest places to visit in January but still want movement, not just sunbeds, Madeira is a smart pick. Come for the hikes, stay for the cafés and the sea air. Based on current 2026 travel trends and Met Office climate data, these are the top 10 results for UK travellers seeking winter sun:

The Bit People Miss When Chasing Heat

Look, chasing warmth is meant to be fun. But the best January trips aren’t just about the highest number on a forecast. They’re about how the day feels. Phuket and the Maldives bring proper heat, the kind that slows you down. Cape Verde and Tenerife give you the warmth you can live in. Dubai sits in the sweet spot where you can actually do things outdoors.

And places like Cape Town and Costa Rica give you sun plus story, so you come home with more than a tan and a laundry pile. So what’s the move? Do you want pure beach, or do you want a bit of life in the mix? Be honest with yourself and your travel mates, then book accordingly. And if you end up in January sunshine while your neighbours scrape ice off their windscreens, don’t feel bad. Just send one polite photo and leave it there, yeah?
