This month marks the beginning of the high season, offering a near-perfect balance of comfortable warmth and clear skies. It is a period characterized by reliable sunshine, gentle breezes, and temperatures that cater to a wide range of vacation activities.
Average Temperature Ranges
The ambient temperature in Cabo San Lucas in December is one of its strongest draws for visitors seeking respite from colder climates. During the day, the mercury typically climbs to a pleasant 78°F (26°C), creating ideal conditions for exploring the coastline or lounging by the pool. As the sun dips below the horizon, the atmosphere cools down significantly, with overnight averages settling around 64°F (18°C). This natural fluctuation means guests can enjoy vibrant evenings without the intense heat of the summer months, making it perfect for both daytime adventures and romantic dinners al fresco.
Daily Highs and Lows
To better understand the daily rhythm of the weather, looking at the specific high and low temperatures is essential. The daily high in December rarely exceeds 81°F (27°C), providing a warm yet manageable environment for hiking, golf, or water sports. Conversely, the daily low usually maintains a comfortable 63°F (17°C). This moderate swing ensures that while days are filled with energy and sunshine, evenings offer a crisp, cool ambiance ideal for wrapping up a day of sightseeing with a light jacket.
Ocean and Sea Conditions
While the air temperature is a primary concern, the condition of the water is equally vital for a beach-centric vacation. The sea temperature in Cabo San Lucas in December remains inviting, averaging around 72°F (22°C). This warmth allows for extended periods of swimming, snorkeling, and paddleboarding without the risk of feeling chilled. Visibility underwater remains excellent, showcasing the rich marine life that makes the Sea of Cortez a world-renowned diving destination. The combination of pleasant air and warm water creates a seamless transition between land and sea activities.
Sunshine and Rainfall
December is firmly entrenched in the dry season for Cabo San Lucas, resulting in exceptionally low rainfall and abundant sunshine. Visitors can expect the sun to shine brightly for approximately 11 hours each day, casting aside any lingering clouds. The chance of precipitation is minimal, usually hovering around 10% on any given day. This reliable weather pattern means that outdoor events, beach picnics, and sunset cruises can be planned with confidence, without the worry of sudden tropical showers disrupting the itinerary.
UV Index and Sun Protection
Even during the winter months, the intensity of the sun in Baja California Sur remains significant. The UV index in December can reach moderate to high levels, particularly between 10 AM and 4 PM. Travelers are strongly advised to utilize high-SPF sunscreen, wear wide-brimmed hats, and utilize sunglasses to protect against sunburn and long-term skin damage. The dry air can be surprisingly dehydrating, so drinking plenty of water throughout the day is crucial to staying comfortable and healthy while enjoying the outdoors.
What to Pack for December
Packing for a trip to Cabo in December requires a strategic approach to accommodate the varying temperature in Cabo San Lucas in December. Lightweight, breathable fabrics like linen and cotton are essential for the daytime heat. However, it is just as important to include layers for the evening. A light sweater, long-sleeve shirt, or denim jacket will prove invaluable when the temperature drops after sunset. Footwear should range from sandals for the beach to closed-toe shoes for exploring rugged terrain or dining in cooler restaurants.
