Planning a Caribbean escape means dodging winter coats for swimsuits, but December weather can be tricky depending on the island. Down south, Curacao in December sits comfortably outside the primary hurricane belt, yet it marks the tail end of the island's brief rainy season. You'll find daytime highs averaging 28°C to 29°C (82°F to 84°F) and warm night lows around 24°C to 26°C (75°F to 79°F). Rain showers happen, but they rarely ruin a whole day.
Knowing what to expect from the climate, trade winds, and daily precipitation helps you pack right and pick the best spots on the island. Here is a complete breakdown of how the weather behaves in December and how to plan your trip around it.
Temperature and Humidity Breakdown
You won't need a sweater after dark in December. The island stays deeply warm year-round, and December is no exception.
- Daytime Highs: Temperatures consistently peak around 28°C to 29°C. Direct sunlight feels intense under a high UV index, making midday shade essential.
- Nighttime Lows: Temperatures drop only slightly after sunset, settling near 24°C to 26°C.
- Humidity: Humidity levels run high this month, often hovering around 75% to 80%. This moisture in the air can make the thermometer reading feel a few degrees warmer than it actually is.
Fortunately, the island's constant trade winds blow steadily from the east, providing a natural cooling relief when you're sitting on the beach or walking through Willemstad.
Understanding December Rainfall on the Island
December is technically part of Curacao's wet season, which runs from October through December. However, "rainy season" in the southern Caribbean looks entirely different from tropical storms further north.
Rain typically arrives as fast-moving, heavy tropical showers that dump water quickly and clear up within an hour. Total monthly rainfall averages between 90 mm and 200 mm depending on the exact pocket of the island, spread across roughly 12 to 16 days with at least some precipitation.
- Timing of Showers: Most downpours happen overnight or in the early morning hours before sunrise. Daytime rain is usually brief and localized.
- Geographic Variation: The northern and western hills, such as Westpunt and Christoffel National Park, tend to catch slightly more green-inducing rain than the arid southern coastlines around Jan Thiel and Willemstad.
- The Silver Lining: These late-year rains bring the island's landscape to life. Cacti bloom, foliage turns deep green, and the island looks much more vibrant than it does during the dry summer months.
According to the Curacao Meteorological Department, short downpours rarely disrupt outdoor itineraries for long, provided you stay flexible with your daily schedule.
Sea Conditions and Water Temperatures
If you're visiting for snorkeling, scuba diving, or swimming, December offers phenomenal aquatic conditions.
- Water Temperature: The ocean hovers at a warm 27°C to 28°C (80°F to 82°F), feeling like a warm bath. You can swim for hours without getting cold.
- Visibility: While heavy morning rain can occasionally stir up coastal sediment near sandy shores, offshore reef visibility generally remains exceptional, often exceeding 30 meters (100 feet).
- Wave Action: The southern sheltered bays like Cas Abao and Playa Lagun stay calm and glassy. However, northern windward shores can experience stronger swells and choppier water due to winter wind patterns.
What to Pack for Curacao in December
Packing for a tropical winter destination requires balancing sun protection with quick-drying rain gear. Avoid heavy fabrics that trap humidity against your skin.
- Light Layers: Pack breathable linen shirts, cotton shorts, and moisture-wicking swimwear. Bring a light rain jacket or compact travel umbrella for sudden evening squalls.
- Footwear: Bring sturdy walking shoes if you plan to hike in Christoffel National Park, plus secure water shoes or reef-safe sandals for rocky entries at secluded beaches.
- Sun Defense: Pack high-SPF, reef-safe sunscreen (mineral-based formulas protect local coral reefs), polarized sunglasses, and a wide-brimmed hat to combat the strong tropical sun.

Common Mistakes to Avoid
Travelers often make a few predictable errors when planning a December trip to the Dutch Caribbean.
- Overpacking for Rain: Don't cancel outdoor plans because a weather app shows a rain icon. Apps often show a 40% chance of rain every single day in December simply because brief 10-minute passing showers happen frequently.
- Ignoring Holiday Crowds: December is a high-demand travel month, particularly the stretch between Christmas Eve and New Year's Day. Booking rental cars, accommodations, and popular excursions months in advance prevents steep last-minute pricing.
- Underestimating the Sun: Because a steady breeze keeps you cool on the beach, it's easy to forget how fast your skin burns. Reapply sunscreen regularly, even when cloud cover rolls in.
