Warm Places to Visit in January: Thailand, Bali, Costa Rica and Morocco

A Tripsit guide

January is when a lot of people in the US want to leave the cold behind. The useful question is not "where is it theoretically warm?" but "where is this month actually in the dry season, and where is it the wet one?" Those two can sit on the same map. Thailand's Andaman coast and Bali are only a short flight apart, and they often have very different January weather.

This guide covers four places we already write about on Tripsit — Thailand, Bali, Costa Rica and Morocco — and what January is typically like in each, based on well-established seasonal patterns, not a forecast for a particular week. We do not quote airfares or hotel rates here, because those change constantly. Check live prices before you book.

How to read "dry season" and "wet season"

Seasonal patterns are averages, not guarantees. A dry-season month can still have a storm. A wet-season day can be clear in the morning and pour in the afternoon. Treat the notes below as planning help, then look at a recent forecast and, for beaches and boat trips, local conditions in the week you travel.

If you are also trying to keep the trip inexpensive, pair this guide with the cheapest international trips from the US. For the tours themselves, see how to book tours abroad and our tours page.

Thailand: the most reliable winter sun of this group

Most of Thailand is in its cool, dry season from about November through February, after the southwest monsoon has eased. That is why January is a classic month for Bangkok, Chiang Mai and the north, and why the Andaman coast — Phuket, Krabi, Koh Lanta and the Phi Phi islands — is usually in good shape for boats and beaches. Days are typically warm; nights in the north can feel cool enough for a light layer.

The important exception is the Gulf coast. Koh Samui, Koh Phangan and nearby islands often get a different rainfall pattern than the Andaman side, and January can still be one of the wetter months there. If your picture of the trip is a beach week in the south, prefer the Andaman side unless you have a specific reason to be on the Gulf and are willing to accept more showers.

January is also high season. Popular day trips sell out, and island boats can be crowded. Book capacity-limited tours once your dates are firm, and compare what is included (lunch, hotel transfer, national-park fees) rather than chasing the lowest headline price. A few starting points, with our usual partner tracking:

Maya Bay has had periodic closures and access rules to protect the bay. Confirm the current itinerary on the tour page before you treat "Maya Bay" as a guaranteed stop. More Thailand ideas are on our Thailand destination page.

Bali: warm, but January is the wet season

Bali is close to the equator, so it stays warm in January. It is also in its wet season, which typically runs from about November through March and is often most noticeable from December to February. Rain is frequently heavier in the afternoon than at dawn, which is why sunrise hikes still run through the wet months, but you should plan on wet days and a flexible itinerary, not on a string of cloudless beach afternoons.

If your main goal is reliable dry weather, Thailand's Andaman coast or Costa Rica's Pacific side are usually the better January bets. If Bali is the trip you want anyway — rice terraces, temples, food, a slower Ubud stay — go in with eyes open: build indoor time into each day, keep a buffer before any flight, and treat outdoor tours as weather-dependent. A Mount Batur sunrise start can still be worthwhile; a boat day to Nusa Penida is more sensitive to swell and rain.

See the full tour list on our Bali page. If you can move the trip, Bali's drier stretch is generally the middle of the calendar year, roughly May through September.

Costa Rica: Pacific dry season, and a shorter flight from much of the US

Costa Rica's Pacific side is typically in its dry season from about December through April. That is the window many travelers mean when they say "Costa Rica in January": Guanacaste and the Nicoya area, the central Pacific around Manuel Antonio, and beach time with a realistic chance of sun. The Caribbean side does not follow the same calendar, and it can be wet when the Pacific is dry, so do not treat the whole country as one climate.

Inland, La Fortuna and the Arenal area are classic January bases for a volcano view, the waterfall, hanging bridges and hot springs. "Dry season" there still does not mean zero showers, especially on the forested slopes, but it is a much more reliable month than mid-year on the Pacific. Monteverde's cloud forest is, by definition, often cloudy and damp; go for the forest and wildlife, not for a beach day.

For many US travelers this is also the practical pick: it is a shorter flight than Southeast Asia, which can matter if you only have a week. Compare current fares rather than assuming it is always cheaper, then put any savings into a couple of well-chosen days rather than a packed tour every morning.

The Monteverde canopy tours we list on the destination page are a good next click if a hanging-bridge or zip-line day is the priority. More options are on our Costa Rica page.

Morocco: winter sun, not tropical heat

Morocco in January is a different kind of escape. Marrakech is often mild in the middle of the day and noticeably cool once the sun drops. The High Atlas and a Sahara camp at Merzouga can be cold at night, sometimes near freezing, even when the sky is clear. Pack layers, a warm sleep layer for a desert tent, and do not plan this as a swim-every-day beach trip. Atlantic towns such as Agadir and Essaouira are usually milder than the interior, but they are still winter destinations by tropical standards.

What January does well is culture and landscape without midsummer heat: the medina, a day in the Atlas or Agafay, or a multi-day trip over the mountains to the dunes. A three-day Marrakech-to-Merzouga itinerary is a long two drives with a night in the desert in the middle. That is a classic trip, and it is also tiring in a small van, so read recent reviews for pacing and whether a desert camp night is included.

Which one should you book?

Wherever you land, compare tours the same way: group size, hotel pickup, entry fees, cancellation rules and recent reviews. That process is spelled out in How to Book Tours Abroad. You can also start from the partner lists on /tours/.

When you are ready to pick a neighborhood, the hotel and rental maps on each destination page are there to compare places to stay. If you would rather ski than thaw out, we cover that separately in our ski vacations guide and the 2026-27 Denver ski season update.

Seasonal weather notes are long-term patterns, not a forecast. Opening hours, boat operations, park rules and prices change. Confirm details on the official tourism, park or tour page before you travel.
