If you’re dreaming of trading frosty winter nights for palm-fringed beaches and sun-drenched days, visiting Jamaica in December delivers just that. With warm, tropical weather that rarely dips below comfortable levels and plenty of sunshine to fuel your escape, December becomes one of the most popular months to experience the island’s natural beauty and vibrant culture.
In this article you will learn what temperature ranges to expect, how the climate influences your travel experience, what to pack, and how to plan your activities for a perfect December getaway.
Average Daytime and Nighttime Temperatures
When you arrive in Jamaica in December, you’ll find the daytime temperatures hovering in the low to mid-80s °F (28-30 °C) in major coastal spots like Montego Bay and Negril. On average, highs around 82-86 °F (28-30 °C) mark the peak of the day. One data set shows daily high temperatures averaging around 84 °F.
As the sun sets, the island remains warm and comfortable. Evening lows generally settle between 70-75 °F (21-24 °C). In some upland or inland areas you might notice slightly cooler evenings, but on the coast you’ll still enjoy mild nights perfect for outdoor dining or strolls. These comfortable swings make December an ideal time for beach and resort outings.
Sea Temperature and Conditions
Another highlight: the water temperature remains delightfully warm in December. The Caribbean Sea around Jamaica averages around 80-82 °F (27-28 °C) at this time of year.
That means swimming, snorkeling or simply floating are highly enjoyable. The sea being this inviting adds a major bonus for travelers looking for water-based relaxation or adventure.
Rainfall, Humidity and Sunshine Hours
In terms of rainfall December marks a favourable shift toward the drier season. Rain showers become less frequent, skies clear up more, and you’ll spend more time outdoors. On average you might encounter about 6-8 rainy days in the month, and precipitation amounts fall compared to the summer months.
Humidity remains present — after all, it’s the tropics — but it moderates a bit compared to peak summer months, making the weather feel more comfortable. You’ll also see around 7-8 hours of sunshine per day, meaning plenty of daylight to explore, relax or adventure. These conditions make December one of the best months climate-wise for Jamaican travel.
Comparing Regions: Coast vs Highlands
While most visitors focus on coastal areas, you should know that temperature and climate vary slightly by region. On the coast (Montego Bay, Ocho Rios, Negril) expect those warm mid-80s °F (around 29-30 °C) highs and mild lows.
If you explore higher elevation zones, such as the Blue Mountains, you’ll encounter cooler temperatures. Mountain peaks and inland districts may be significantly cooler, especially at night—think 60s °F (15-18 °C) or even lower depending on elevation. For most beach-seeking travelers, sticking to the coast offers the consistent warmth you expect in December.
Why December Is a Strong Choice for Visiting
From a weather standpoint December hits a sweet spot. You avoid the heavy rainfall of the summer wet season, skip much of the hurricane risk which peaks earlier, and get warm, stable weather to support beaches, outdoor dining and sightseeing.
December is considered the start of the peak tourist season for Jamaica, largely because the climate lines up so well for good weather. The combination of warm air, gentle sea breezes, and a warm sea make it exceptionally travel-friendly.
What This Means for Your Travel Experience
Because the weather is favourable, you’ll find yourself able to do more: beach days from morning to late afternoon, outdoor excursions, evening gatherings on patios, and water sports without the constant threat of heavy rain.
Resorts and destinations enjoy a lively vibe, partly driven by holiday travel, and the weather supports it. Expect comfortable evenings and event-friendly conditions. That said, because it is a popular month, prices may be higher and availability more limited—one reason to plan ahead.
What to Pack for Jamaica in December
Since you’ll enjoy warm days and mild nights, your packing list can be relatively simple:
- Lightweight cotton or linen clothing for daytime comfort
- Swimsuit, cover-up and sandals for beach and pool use
- Sunglasses, sunhat, and reef-safe sunscreen for strong tropical sun
- Light sweater or wrap for cooler evenings or breezy dinners outdoors
- Insect repellent, especially if you venture away from resort zones
- A waterproof jacket or small umbrella—while rainfall is lower, short tropical showers can still occur
Activities Suited to December Weather
With the weather cooperating, you can plan a full range of experiences:
- Morning beach time followed by snorkeling or paddleboarding in warm, calm seas
- Afternoon rainforest or waterfalls tours (the cooler yet warm temperatures make hiking comfortable)
- Evening rooftop bars, beachfront dinner or sunset cruises under pleasant skies
- Holiday-season events: Jamaican Christmas and New Year celebrations combine with the island’s festive culture under ideal weather conditions
- Water-based fun: the warmed sea and good visibility make diving or snorkelling particularly satisfying in December
Travel Tips and Considerations
- Book early: Because December is a top travel month, flights, resorts and excursions fill up fast.
- Expect slightly higher prices: Peak season often carries premium pricing, so consider your budget accordingly.
- Crowds may increase: While you’ll enjoy fabulous weather, some resorts may feel busier. If you prefer quieter surroundings, consider early-December or select venues that limit guest numbers.
- Monitor weather forecasts: While the climate is stable, short showers or isolated fronts may still pop up; having flexibility is always wise.
- Inland excursions are fine—just prepare for slightly cooler and breezier conditions if you leave the coastline.
