What to Pack for December Weather in Cabo
Packing light, breathable clothing is essential for daytime, with moisture-wicking fabrics helping you stay cool under the sun. Because evenings in December can feel noticeably cooler, especially near the water, bring a couple of long-sleeve shirts, a light sweater, and comfortable layers.
Sun protection deserves priority, so include a wide-brim hat, sunglasses, and a high-SPF sunscreen that you reapply regularly. A light windbreaker or cardigan is useful for coastal breezes, while sandals, closed-toe shoes, and a pair of dressy sandals for evenings give you flexibility.
For water-based activities, quick-dry swimwear, a rash guard, and water shoes protect against sun and rockiness on the beach. Pack a compact, reusable water bottle to stay hydrated, and consider a small daypack for excursions, making it easy to adjust as temperatures shift through the day.
December Weather Patterns and Sea Conditions
December marks the start of the dry season in Cabo, characterized by lower humidity, minimal rainfall, and stable high-pressure conditions. Daytime skies are mostly clear, giving way to spectacular sunsets with vibrant oranges and deep purples over the Sea of Cortez.
Sea temperatures remain comfortably warm for swimming, hovering around 22–24°C, which is refreshing rather than cold. The reduced rain and moderate winds create excellent conditions for boating, fishing, and exploring nearby islands without the summer’s intense heat or humidity.
Because the region lies in a desert climate zone, even in the “cooler” season, midday heat can still be strong. Travelers should plan outdoor activities for late morning to early afternoon, then transition to shaded cafés, cultural sites, or spa time as the sun lowers toward evening.
Outdoor Activities and Event Opportunities
Beach and Water Adventures
December’s favorable weather supports surfing at spots like Medano Beach, stand-up paddleboarding in calm coves, and snorkeling among marine life near El Arco. The trade winds are gentle, keeping the sea relatively calm for both beginners and experienced water-sports enthusiasts.
Fishing and Boat Tours
Deep-sea fishing season is productive in December, with marlin, sailfish, and dorado often biting. Sunset sails and whale-watching excursions are also popular, as migrating humpback whales pass through nearby waters, offering dramatic surface breaches and tail slaps.
Cultural and Culinary Experiences
Festive markets, holiday events, and open-air concerts add cultural texture to visits in December. Indoor attractions such as art galleries, museums, and cooking classes provide comfortable backups on occasional breezy evenings, ensuring plans stay flexible regardless of short-term weather changes.
Comparing Cabo December to Peak Summer
While summer in Cabo promises long, hot days and vibrant nightlife, December delivers a more relaxed pace with milder temperatures and lower humidity. Travelers sensitive to heat often find December more comfortable for extensive sightseeing and extended outdoor dining.
Price differences can be notable, with summer deals sometimes available, yet December’s demand around holidays can elevate costs. Weighing comfort, crowd levels, and activity availability helps you choose the right season based on your travel priorities and budget.
Smart Planning for Your December Cabo Trip
- Check the forecast a few days before arrival and pack layers for warm days and cooler evenings

- Bring reef-safe sunscreen and sun protection to enjoy the strong UV index comfortably
- Stay hydrated throughout the day, even when temperatures feel milder than peak summer heat
- Confirm activity times with local guides, as early mornings and late afternoons offer the best conditions
