Yes — you can spend December somewhere warm for under $1,000 all-in from the US. The trick is flying against the holiday crowds: these destinations have peak weather in December but off-peak prices, because most Americans are flying somewhere else.
December is the month everyone assumes is unaffordable, and for the classic routes — Cancún, Miami, Hawaii — they're right. But the smartest December trips run in the opposite direction: places where the dry season is just starting, hotels are still hungry, and fares from US hubs dip while everyone else bids up flights home for the holidays.
Every price below is a real "from" fare verified this week from major US hubs, and every destination earns its spot with a specific reason to go in December — not just sun.
San Juan, Puerto Rico

Flights from the East Coast regularly drop to the low $200s in the first two weeks of December, before Christmas week sends everything up, and a guesthouse stay in Santurce or Ocean Park runs a fraction of what the beachfront resorts in Condado charge.
Oaxaca Coast (Puerto Escondido & Mazunte)

Fares into Puerto Escondido's growing airport start around $180 round trip from Houston and Dallas early in the month, and a beachfront cabana in Mazunte still costs what a breakfast buffet costs in Cancún.
Medellín, Colombia

Flights from Miami and New York start near $320 round trip if you fly before December 15, and your dollar goes roughly three times further than at home.
La Fortuna, Costa Rica

Flights into San José from Miami, Houston and LA hover around $230 round trip in the first half of the month, and eco-lodges with volcano views that charge $120 in February still list rooms in the $50–60 range.
Book December trips before the end of October — holiday demand pushes fares up steadily from early November. Fly out in the first two weeks of the month and you'll pay off-peak prices for peak weather almost everywhere on this list.

- CALENDARFly out between December 1 and 14, before holiday demand reprices every route on this list.
- PRICE ALERTSSet an alert per route and book on the dip instead of guessing when fares will move.
- MONEYBudget lodging first: stays vary far more than flights and drive most of the total cost.
- FLIGHTTuesday and Wednesday departures consistently price below weekend flights on these routes.
December doesn't have to mean paying December prices
The pattern across all four destinations is the same: peak weather arrives a few weeks before peak pricing, and that gap is where your budget lives. Pick the place that matches your energy — beach mornings in Puerto Rico, volcano hikes in Costa Rica, city nights under Medellín's lights — and book the first half of the month.
