January is the month people actually leave. The holidays are over, the weather has stopped being festive and started being a slog, and the phrase “I need to get out of here” gets said out loud.
It’s also peak season everywhere warm, which means the weather question is easy and the price question is brutal — with one significant exception.
The exception, first
January 2–10 is the sharpest price drop on the winter calendar.
Everyone just got home. Nobody is traveling. Schools are back. And the weather is identical to the fortnight that cost twice as much. If you have any flexibility on which week you go, this is the single best-value week between November and April.
After roughly January 10, pricing settles into standard high season and stays there until spring.
The shortlist
| Destination | Typical high | Rain risk | Est. week for two | The honest note |
|---|---|---|---|---|
| Aruba | 84°F | Very low | $2,300 | Most weather-reliable week you can buy. Priced accordingly |
| Curaçao | 84°F | Very low | $2,000 | Same weather, cheaper, better food |
| Costa Rica (Guanacaste) | 90°F | Very low | $1,800 | Hottest option. Dry season fully in |
| Puerto Vallarta, MX | 82°F | Very low | $1,500 | Peak whale season. Excellent value |
| Puerto Rico | 83°F | Low | $1,700 | No passport. Most varied trip here |
| Belize | 82°F | Very low | $1,900 | Reef and jungle in one week |
| Phoenix, AZ | 66°F | Very low | $950 | Cheapest. Warm days, cold nights |
| Canary Islands, ES | 70°F | Low | $1,400 | Europe’s answer. Warm, not hot |
| Cabo San Lucas, MX | 76°F | Very low | $1,700 | Driest air, coolest sea |
| Maui, HI | 81°F | Moderate | $5,900 | Best water temps. Long flight, high cost |

What January does differently
The sea is at its coolest. Water temperature lags air temperature by about a month, so January and February are the low point even where the air is warm. This matters most on Mexico’s Pacific coast — Cabo in January has genuinely brisk water despite pleasant air. The Caribbean holds up much better.
The northern edges get cold fronts. The Bahamas, South Florida, and northern Mexico all see occasional fronts that push highs into the 60s for a few days. The further south you go, the less this happens. Below about 15° latitude — Aruba, Curaçao, Costa Rica — it essentially doesn’t.
It’s the driest month in most of the shortlist. If reliability is what you’re buying, January delivers it better than any other month here.
Booking January
If you’re reading this in August or September, book now. This is the ideal window and prices only move one way from here.
If you’re reading this in November or December, target that January 2–10 week specifically, and use substitution for everything else — Curaçao over Aruba, Oaxaca over Vallarta, Mazatlán over Cabo.
And while you’re booking January, book late April too. January is when genuinely good late-April and May deals appear, because demand for spring collapses the moment the holidays end.
