December Weather in Lombok
Is December Right for You?
Advantages
- Shoulder season pricing with 20-30% lower accommodation rates compared to July-August peak, yet you still get excellent weather - most days are sunny with only brief afternoon showers that actually cool things down nicely
- The transition into wet season means landscapes are lush and green without the brown, dusty conditions you'd see in September-October. Waterfalls like Tiu Kelep and Benang Stokel are flowing beautifully but trails aren't muddy yet
- Surf conditions hit a sweet spot - south coast beaches like Selong Belanak and Mawi get consistent 1-1.5m (3-5 ft) swells perfect for intermediates, while the crowds from Australian school holidays haven't arrived yet (they come mid-December onward)
- Sea visibility for snorkeling and diving around the Gili Islands typically ranges 15-25m (50-80 ft) - clearer than wet season proper (January-March) but without the strong currents you sometimes get in peak dry season
Considerations
- Weather becomes genuinely unpredicular in early December 2026 - you might get 3 perfect days followed by a grey, drizzly afternoon. This makes planning boat trips tricky, and operators occasionally cancel Gili island fast boat services with only a few hours notice when swells pick up
- Humidity sits around 70% which means your clothes never fully dry, electronics feel sticky, and that 28°C (82°F) feels closer to 32°C (90°F) when you're hiking. Pack moisture-wicking fabrics, not cotton
- Mount Rinjani trekking season officially closes around December 15th due to increased lightning risk and slippery trails - if summiting the volcano is your main reason for visiting, come between May and November instead
Best Activities in December
South Coast Surf Lessons and Board Rentals
December brings the kind of consistent, manageable swells that make Lombok's south coast beaches ideal for learning. Selong Belanak gets clean 1-1.5m (3-5 ft) waves with sandy bottoms - perfect for first-timers who don't want to get smashed on reef. The humidity is high but ocean temperatures hover around 28°C (82°F), so you're in boardshorts only. Early morning sessions (6:30-9am) give you glassy conditions before the sea breeze kicks in around 10am. Worth noting that December sits right before the Australian Christmas rush, so beaches feel spacious and instructors aren't stretched thin.
Gili Islands Snorkeling Day Trips
The three Gili Islands offer some of Indonesia's most accessible snorkeling, and December weather is actually ideal - seas are calm enough that fast boats run reliably (unlike January-February), but water visibility stays strong at 15-20m (50-65 ft) because heavy rains haven't stirred up sediment yet. You'll see green turtles at multiple sites around Gili Meno and Gili Trawangan without fail. The 70% humidity feels less oppressive when you're in and out of water all day. Most tours depart 9am and return by 4pm, hitting 3-4 snorkel sites plus beach time.
Traditional Sasak Village Cultural Tours
December's variable weather makes this the perfect time for cultural immersion that doesn't depend on sunshine. Villages like Sade and Rembitan in central Lombok showcase traditional thatched-roof architecture and weaving techniques that have barely changed in centuries. December timing means you'll catch the tail end of rice harvest season - you might see farmers working paddies in early morning before rains threaten. The humidity actually helps with traditional ikat weaving demonstrations, keeping threads supple. Tours typically run 3-4 hours including stops at pottery villages where women still hand-build clay using techniques passed down matrilineally.
Waterfall Trekking to Tiu Kelep and Sendang Gile
December sits in that sweet spot where waterfalls are flowing impressively from early wet season rains, but trails haven't turned into mudslides yet. The trek to Tiu Kelep involves crossing a river 3-4 times and navigating some slippery rocks - the 22°C (72°F) morning temperatures make this comfortable, unlike the sweltering heat of September. Plan for 2.5-3 hours round trip covering roughly 3km (1.9 miles) with 150m (490 ft) elevation gain. The payoff is standing under a 42m (138 ft) waterfall with actual force behind it. That said, if it's rained heavily the night before, guides might redirect you to just Sendang Gile, the lower falls, which is still spectacular.
Sunset Seafood Dining at Senggigi Beach
While this isn't exactly an adventure activity, December evenings in Senggigi offer something special - the variable weather creates dramatic cloud formations that make for spectacular sunsets around 6:15-6:30pm. The beachfront restaurant scene has improved significantly, with fresh-grilled seafood becoming more affordable as fishing conditions are good in early wet season. You're looking at 150,000-300,000 IDR per person for grilled snapper or prawns, rice, vegetables, and a couple of Bintangs. The 70% humidity drops slightly after sunset, and the ocean breeze makes evenings genuinely pleasant. This is when locals come out too, so you get a more authentic vibe than midday tourist rushes.
Motorbike Coastal Rides Along Southwest Peninsula
December weather is actually ideal for independent motorbike exploration - mornings are clear and dry, giving you 4-5 solid hours before afternoon showers typically roll in around 2-3pm. The coastal road from Kuta through Selong Belanak to Belongas Bay covers roughly 45km (28 miles) of stunning clifftop views, empty beaches, and traditional fishing villages. Roads are in decent shape (Lombok standards - meaning some potholes but generally paved), and traffic is light compared to Bali. The variable conditions mean you'll see dramatic cloud formations over the ocean. Just know that if you get caught in a downpour, visibility drops fast and roads get slippery within minutes.
December Events & Festivals
Peresean Stick Fighting Demonstrations
While not tied to specific December dates, traditional Peresean stick fighting demonstrations happen more frequently in December as villages celebrate successful rice harvests. Two fighters armed with rattan sticks and cowhide shields battle until first blood in what's essentially ritualized combat dating back centuries. It's raw, occasionally brutal, and unlike anything you'll see elsewhere in Indonesia. Demonstrations typically occur in central Lombok villages on weekends, often announced only days in advance through local networks.
