Visiting Aruba in December: Everything To Know

Thinking about visiting Aruba in December? This is when the island begins transitioning from its modest rainy season into the brighter and slightly cooler winter travel season. Expect warm beach weather, comfortable trade winds, festive decorations, and increasingly busy resorts as Christmas approaches.

Here is your December guide to the island—from climate and tourism demand to daylight hours, sargassum conditions, and the best experiences.

Aruba Weather in December

December brings warm temperatures, swimmable water, refreshing breezes, and generally reliable beach weather. Brief tropical showers remain possible, particularly earlier in the month, but they rarely ruin an entire day.

Temperature

Average temperatures reach approximately 87°F (31°C) during the day and fall to around 77°F (25°C) at night.

The evenings remain warm enough for outdoor dinners and beach walks, although the steady breeze can make it feel slightly cooler after sunset.

Rainfall & Trend

December is technically the final month of Aruba’s modest rainy season, which generally runs from October through December.

Rainfall figures vary depending on the weather station and averaging method, but most estimates place December rainfall between approximately 1 and 3 inches. Showers are usually brief, scattered, and followed by sunshine rather than lasting all day. Rainfall also tends to become less frequent as the month progresses.

Humidity & Climate

Average humidity is around 77%, but Aruba’s easterly trade winds make the tropical conditions feel more comfortable than they would on a less-breezy Caribbean island.

December is noticeably more pleasant than the hotter and less windy early-fall months, especially when exploring beaches or outdoor attractions.

Water Temperature

The Caribbean Sea remains comfortably warm throughout December, generally ranging from approximately 80°F to 82°F (27°C to 28°C).

The water is warm enough for extended swimming, snorkeling, paddleboarding, and boat excursions without needing a wetsuit.

December Weather Summary

December offers classic Aruba weather: warm days, breezy evenings, inviting water, and plenty of sunshine between occasional passing showers.

Sunrise & Sunset in December

• Daylight Hours: Aruba receives approximately 11 hours and 24 minutes of daylight throughout most of December.
• Sunrise Time: Sunrise shifts from around 6:45 AM at the beginning of the month to approximately 7:00 AM near the end.
• Sunset Time: Sunset moves from around 6:12 PM early in December to approximately 6:25 PM by New Year’s Eve.

The amount of daylight changes very little during the month, giving you enough time for a morning beach visit, an afternoon excursion, and sunset along the western coast. Exact times can vary by a minute or two depending on the year.

December is Peak Season in Aruba

Tourism Demand & Pricing

December marks the beginning of Aruba’s peak tourism season, which generally continues through April. Demand rises as travelers from North America and Europe head south for warmer weather.

The first part of December can feel more manageable, but resorts, vacation rentals, restaurants, rental cars, and tours become much busier around Christmas and New Year’s. Accommodation prices are also typically higher than during the fall.

Anyone traveling during the final two weeks of December should reserve accommodations and flights well in advance. I would begin comparing options several months before the trip, particularly when staying near Palm Beach or Eagle Beach.

Value & Vibe

Early December provides the best balance of the month. The island already has warm winter weather and holiday decorations, but it may not yet have reached the intense demand of Christmas week.

Late December is livelier and more expensive, but it also offers Aruba’s biggest holiday atmosphere, elaborate light displays, resort celebrations, firecrackers, and New Year’s Eve festivities.

Best Things To Do in December

December’s comfortable weather makes it easy to combine beach time, sightseeing, water activities, and holiday celebrations.

Beach Life & Water Fun

Spend a calm morning at Eagle Beach, Palm Beach, or Arashi Beach. The western coastline generally has calmer water, soft sand, and easy access to swimming, snorkeling, watersports, restaurants, and beach facilities.

For snorkeling, consider Boca Catalina, Arashi Beach, or Mangel Halto. Morning trips are usually best because visibility can be clearer before afternoon activity increases.

Explore Arikok National Park

December is an excellent month to visit Arikok National Park because temperatures are slightly cooler than during Aruba’s hottest months.

Explore the desert scenery, limestone caves, rugged coastline, and natural landmarks early in the morning. A four-wheel-drive vehicle or guided tour is recommended for rougher areas, particularly when heading toward the Natural Pool.

Experience Aruba’s Holiday Celebrations

Aruba becomes increasingly festive throughout December. Streets, traffic circles, hotels, businesses, and homes are decorated with colorful Christmas lights.

Early December includes local Sinterklaas traditions, while Christmas week brings family gatherings, seasonal foods, music, and illuminated displays. The House of Lights in Seroe Preto is one of the island’s best-known holiday attractions.

Travelers staying through New Year’s Eve can also experience Aruba’s famous pagara firecrackers, fireworks, resort parties, and island-wide celebrations.

Explore Oranjestad and San Nicolas

Walk through Oranjestad to see Dutch Caribbean architecture, waterfront shopping areas, local restaurants, museums, and colorful buildings.

For a different atmosphere, visit San Nicolas to see its murals, galleries, street art, and nearby southern beaches. December’s breezier conditions make daytime exploration more comfortable than during the hotter fall months.

Take a Sunset Cruise

December’s warm evenings are ideal for a sunset sail along Aruba’s western coastline. Most cruises depart near Palm Beach and include views of Eagle Beach, the hotel zone, and the California Lighthouse area.

The sun sets shortly after 6:00 PM, so sunset cruises generally leave during the late afternoon.

Sargassum in Aruba in December

Overview & Seasonality

• December is generally considered a lower-risk month for major sargassum arrivals than late spring and summer.
• Conditions still vary from year to year because floating seaweed is influenced by ocean currents, wind, and regional bloom activity.
• Aruba can receive sargassum, but it usually does not affect every coastline equally.

Beach Impact & Geography

Aruba’s rougher eastern and northern shorelines are more exposed to wind, waves, and floating debris. These areas are more likely to experience temporary seaweed accumulation.

The popular resort beaches along the calmer western and northwestern coast—including Palm Beach, Eagle Beach, and Arashi Beach—are generally less exposed. Conditions can still change from one day to the next, so no Caribbean island can guarantee a completely seaweed-free shoreline.

Local Mitigation

Resorts and businesses regularly maintain the main tourism beaches. When small amounts of seaweed or marine grass wash ashore in front of hotels, cleanup crews generally remove it quickly.

Natural beaches along Aruba’s rugged coast may not receive the same level of grooming, particularly inside protected or undeveloped areas.

Sargassum Overview

Significant sargassum is unlikely to dominate an Aruba vacation in December. Small or isolated accumulations remain possible, especially along wild and wind-exposed shores, but the main resort beaches are typically dependable choices.
