December in Cabo San Lucas presents a distinct transition as the region bids farewell to the lingering warmth of autumn. This month marks the definitive start of the high season, attracting visitors seeking reliable sunshine and comfortable temperatures after the summer heat subsides. While the intense summer storms have long since cleared, the humidity begins its gradual retreat, creating an environment that feels significantly more pleasant than the preceding months. Travelers will find that the weather during this period offers a near-perfect balance for outdoor activities, setting the stage for memorable experiences.
Temperature and Climate Overview
The defining feature of Cabo weather in December is the reliable warmth coupled with low humidity. Daytime temperatures typically settle in a very comfortable range between 78°F and 82°F (26°C to 28°C), providing ideal conditions for beach time and exploration. Evenings cool down nicely to an average of 61°F to 64°F (16°C to 18°C), making light layers a wise choice for dinner or evening strolls along the marina. This moderate climate is the primary reason the region sees a significant influx of visitors during this time, effectively escaping colder winter conditions elsewhere.
Ocean Conditions and Swimming
Sea temperatures in December remain inviting for swimmers, holding steady at approximately 71°F (22°C). While slightly cooler than the peak summer months, this temperature is certainly refreshing and suitable for extended periods in the water. The Pacific Ocean maintains its characteristic clarity, though the underwater visibility may be slightly better in the cooler months. Swimmers should be aware that the water can feel brisk, and it is not uncommon to see locals and tourists alike enjoying quick dips rather than prolonged swims. For those engaging in water sports, the slightly cooler air temperature often means the water feels warmer in comparison, enhancing the overall experience.
Sunshine, Rainfall, and Sky Conditions
December is one of the driest months in Cabo, characterized by an abundance of sunshine and minimal rainfall. The region enjoys an average of 10 to 11 hours of daylight, with the sun rising around 7:00 AM and setting near 5:30 PM. Precipitation is scarce, with historical averages indicating less than half an inch of rain for the entire month. When showers do occur, they are typically brief and isolated, clearing quickly to reveal brilliant blue skies. The low humidity levels contribute to sharp, clear views, making the scenery of the Sea of Cortez and the iconic rock formations more striking than ever.
Low average rainfall ensures mostly dry conditions for outdoor plans.
Abundant sunshine supports activities like golf, hiking, and sailing.
Gentle breezes from the ocean provide natural cooling and relief.
Evening temperatures drop sufficiently to require a light jacket.
Wind and Its Impact on the Experience
While generally calm, December can experience moderate winds, particularly in the late afternoon. These breezes, often referred to as the "Brisa," originate from the Pacific Ocean and provide a natural cooling effect that is appreciated during the warmest parts of the day. For sailors and kite surfers, these winds can create excellent conditions on the bay side of the peninsula. However, on the ocean side, which faces the open Pacific, these winds can generate choppier waters and stronger waves. This dynamic is important for visitors to consider when planning specific water-based excursions, as conditions can vary significantly depending on the exact location along the coast.
