December in Los Cabos marks a pivotal shift in the Baja California Peninsula’s climate, transitioning from the tail end of the warm autumn into the beginning of a season that defines the region’s appeal. While the summer heat begins to recede, the days remain predominantly sunny and the nights offer a pleasant coolness that is ideal for both relaxation and exploration. This period represents a sweet spot for visitors, where the intense midday sun is tempered, and the clear, blue skies provide a perfect backdrop for enjoying the peninsula’s iconic desert meets ocean scenery.
Average Temperature Ranges
Understanding the typical temperature parameters is essential for planning any trip to Los Cabos in December. The climate during this month is characterized by distinct yet comfortable variations between daytime highs and nighttime lows. Travelers can generally expect daytime temperatures to hover in a warm range, while evenings provide a refreshing cool-down that is neither harsh nor abrupt.
Daytime Highs
Daytime conditions are typically sunny and warm, though not oppressively hot as seen in the late summer months. The average high temperature usually sits comfortably in the mid to upper 70s Fahrenheit (mid 20s Celsius). This creates an ideal environment for outdoor activities such as swimming, snorkeling, or simply lounging on the pristine beaches without the risk of overheating or severe sunburn that is more common earlier in the year.
Nighttime Lows
As the sun dips below the horizon, the temperature drops significantly, offering a crisp and clear evening atmosphere. Average low temperatures often fall into the mid-50s to low 60s Fahrenheit (around 12-16°C). This coolness necessitates packing a light jacket or sweater for the evenings, especially for those planning to dine outdoors or participate in evening excursions. The low humidity at night makes the cool air feel sharp and invigorating rather than damp and cold.
Ocean and Weather Conditions The Pacific Ocean and the Sea of Cortez play a crucial role in moderating the climate of Los Cabos, even during the cooler winter months. December is generally considered the beginning of the "dry season," which brings a host of favorable conditions for travelers seeking reliability and sunshine. Precipitation and Humidity Rainfall in Los Cabos during December is minimal and infrequent. The region experiences very little precipitation, often going weeks without a significant shower. When it does rain, it is usually a brief, isolated event rather than the prolonged downpours seen during the summer hurricane season. The humidity levels remain relatively low, contributing to a comfortable environment where the cool breeze feels pleasant rather than clammy. Sunshine and Daylight December offers some of the clearest skies of the year. The average daily sunshine duration is high, providing ample hours of direct sunlight. Daylight hours are shorter than in the summer, with sunrise typically occurring around 7:00 AM and sunset near 5:30 PM. This earlier sunset creates a cozy evening ambiance, perfect for enjoying warm dinners at outdoor restaurants or watching the sunset from a cliffside bar without staying out excessively late.
