Planning a trip to Cabo San Lucas in December? Weather plays a bigger role than you might think. It determines what you pack, which tours make sense, and how you'll spend your days. Some months bring perfect beach weather; others favor jungle adventures or whale watching.
This guide breaks down exactly what to expect from Cabo's weather in December. We'll cover temperatures, rain patterns, ocean conditions, and how they affect your plans. By the end, you'll know if December fits what you're looking for and how to make the most of it.
What's the Average Temperature in Cabo During December?
December brings some of Cabo's most comfortable weather of the year. Daytime highs typically range from 25°C to 28°C (77°F to 82°F), creating perfect conditions for outdoor activities and sightseeing. The overall temperature averages around 20°C (68°F), making it ideal for visitors escaping colder winter climates elsewhere.
How Hot Does It Get in Cabo in December?
Peak heat in December is pleasantly manageable, with the warmest parts of the day reaching 28°C (82°F). Unlike summer months, you won't face oppressive heat or high humidity that makes outdoor activities uncomfortable. The moderate humidity of 60-85% means the temperature feels exactly as it reads—no sticky, overwhelming heat that characterizes tropical summer destinations.
Is It Cold in Cabo in December?
Cold weather isn't a concern during December days in Cabo. While evenings can feel surprisingly cool, with temperatures dropping to 13°C to 16°C (55°F to 61°F), you'll get pleasant coolness rather than actual cold.
Late December nights tend to feel the coolest, but nothing that requires heavy winter clothing—just a light sweater or jacket for comfort.
What's the Temperature Like at Night in Cabo in December?
Nighttime temperatures drop significantly from daytime highs, ranging from 13°C to 16°C (55°F to 61°F). Evening outdoor dining or sunset activities can feel chilly without layers, especially near the coast where ocean breezes add to the cooling effect. A light sweater, cardigan, or jacket is essential for comfortable evenings, especially in late December when the chill is more pronounced.

Is the Water Warm Enough to Swim in December?
The Sea of Cortez maintains comfortable swimming temperatures in December, averaging 22°C to 24°C (72°F to 75°F). While slightly cooler than peak summer months when water reaches 28°C (82°F), it's still perfectly swimmable for most visitors. The water feels refreshing rather than bath-like, making it ideal for swimming, snorkeling, and water sports.
For extended scuba diving sessions or those sensitive to cooler water, a wetsuit might be preferred, though many find the temperature comfortable without one.
Does It Rain in Cabo in December?
Rain is extremely rare in December. Cabo experiences only about 6mm of rainfall over the entire month, with a mere 2% chance of rain on any given day. Most visitors go through their entire December vacation without encountering a single rainy day. When rain does occur, it's typically brief and light, rarely disrupting outdoor plans or activities.
How Much Rain Should You Expect in Cabo in December?
Expect virtually no rain during your December visit. The month typically sees only 6-16mm of total precipitation, usually occurring over just one day or less. December falls squarely in Cabo's dry season, with some years experiencing no measurable rainfall at all. Any showers that do occur are brief afternoon events rather than all-day rain patterns.
Is December Part of the Rainy Season in Cabo?
December is not part of Cabo's rainy season —quite the opposite. December marks the heart of the dry season, which extends roughly from November through June. The wettest month, September, sees 18% daily rain chances and up to 116mm of precipitation, making December's near-zero rainfall a stark contrast. This positioning makes December one of the most reliable months for sunny, dry weather.

Should You Worry About Storms in December in Cabo?
Severe weather is extremely unlikely in December. Cabo is well outside hurricane season, which runs from June through November. December weather patterns are remarkably stable, with no tropical storms or severe weather systems affecting the region. The biggest weather "concern" might be occasional stronger ocean breezes, but nothing that poses safety risks or significantly disrupts activities.
Is It Windy in Cabo in December?
December brings moderate ocean breezes averaging around 3.8 m/s (13-14 km/h, 8 mph). These winds are generally pleasant, providing cooling relief during warm afternoons and creating ideal conditions for sailing and windsurfing.
The breezes rarely become strong enough to create uncomfortable beach conditions or rough seas that would impact water activities. Instead, they contribute to the comfortable, tropical atmosphere that makes December so appealing.
What Wildlife Shows Up in Cabo in December?
December opens Cabo's premier wildlife season. Humpback and gray whales arrive to mate and give birth in the warmer waters of the Sea of Cortez, and by December 15th, the official whale-watching season in Cabo is in full swing, with breaches and tail slaps visible right off the coast.
Just north in La Paz, whale sharks reach peak visibility, feeding near the surface and creating one of the year's most unforgettable moments for anyone swimming with whale sharks. Sea lions stay active at their Land's End colony, sardine bait balls draw in predators for dynamic underwater spectacles, and Munk's devil rays often gather in schools of hundreds that leap dramatically from the water in late November and early December.
Does the Weather Affect Tours in Cabo During December?
December's stable weather rarely affects tour availability. Dry conditions and calm seas mean outdoor activities proceed as scheduled, and tour cancellations are extremely rare. Ocean conditions are typically ideal for whale watching, snorkeling, and diving excursions.
The comfortable temperatures make land-based days equally reliable, whether you're carving through canyons on the Cabo ATV Tour & Desert Adventure or heading out on a coastal hike. December's predictable weather actually makes it easier to book tours in advance, as you can count on favorable conditions for your planned activities.
What to Bring for Cabo in December
Weather determines everything you pack. December's conditions in Cabo mean you'll want lightweight, breathable clothing for warm days and light layers for cooler evenings. Pack swimsuits for the warm sea, sun protection including wide-brimmed hats and sun-protective clothing, and a light sweater or jacket for after-sunset activities. Water shoes help on rocky beaches, while comfortable sandals handle most other situations.
