December in Bali means diving headfirst into the island's lush, tropical wet season. Expect vibrant greenery, dramatic skies, and a unique, less-crowded experience — but packing smart is key to embracing the elements!
We'll tune the list to your exact trip — dates, activities, and weather.
In December, Bali experiences its rainy season, with average high temperatures hovering around 89°F (32°C) and lows rarely dropping below 77°F (25°C). You can anticipate frequent, heavy downpours, often in the afternoon, with rainfall averaging around 10 inches (250mm) throughout the month. Humidity is consistently high, typically 80% or more, making the air feel thick and tropical. Expect around 12 hours of daylight.
Lightweight, breathable clothing is your best friend in Bali's December humidity. Think natural fabrics like cotton or linen. While beachwear is common, remember to pack modest options for temple visits, covering shoulders and knees to respect local customs.
Lightweight Rain Jacket
A packable, breathable rain jacket is crucial for navigating sudden downpours without getting soaked to the bone.
Waterproof Daypack
Keep your electronics, passport, and other essentials dry during unexpected rain showers or boat trips.
Quick-Dry Travel Towel
Essential for drying off after a swim, a sudden downpour, or simply when you need a quick refresh in the humidity.
Insect Repellent with DEET
Mosquitoes are more prevalent during the wet season, so a strong repellent is vital to avoid bites and potential diseases.
Sturdy Sandals or Water Shoes
Perfect for navigating wet streets, muddy paths, or walking on the beach, and they dry quickly.
Sarong or Lightweight Scarf
Invaluable for covering up at temples, providing extra sun protection, or simply as a versatile cover-up.
Portable Power Bank
Keep your devices charged on the go, especially if you're out exploring and away from power outlets for extended periods.
Small Umbrella
A compact umbrella offers quick protection from sudden rain and can also provide some shade from the intense sun.
Sunscreen (Reef-Safe)
Despite the rain, the sun is still strong, so protect your skin, and choose reef-safe options to preserve Bali's marine life.
Lightweight Long-Sleeved Shirt
Offers sun protection during the day and can help ward off mosquitoes in the evenings, without adding bulk or heat.
First-Aid Kit with Anti-Diarrhea Medicine
Minor scrapes or stomach upsets can happen, and having your own supplies means you're prepared for anything.
Dry Bags
Beyond a waterproof daypack, individual dry bags add an extra layer of protection for valuables like cameras or phones.
December's rain transforms Bali into an even more vibrant, lush paradise. Embrace the dramatic skies and fewer crowds by focusing on inland activities like rice paddy treks and waterfall visits, which are at their most spectacular.
Plan your outdoor activities for the mornings, as heavy rain often rolls in during the afternoons. This allows you to explore before the downpours and relax during the heaviest part of the day.
Despite the rain, the high humidity can lead to dehydration. Drink plenty of bottled water throughout the day to stay comfortable and energetic.
Wet conditions mean slippery roads and pathways. Wear appropriate footwear with good grip and take extra caution when walking or riding scooters.
Weather in the wet season can be unpredictable. Be prepared to adapt your plans if a sudden storm arises, and consider having indoor alternatives for some days.
Not at all! While it's the wet season, the rain often comes in heavy, short bursts, usually in the afternoon. This leaves plenty of sunshine for morning activities and results in fewer tourists and incredibly lush landscapes. You can still have a fantastic trip if you pack appropriately and plan around the downpours.
For temple visits, always pack a sarong or a lightweight scarf and clothes that cover your shoulders and knees. Many temples provide sarongs for rent, but it's always good to have your own. Lightweight, breathable materials are best for comfort in the humidity.
Due to the wet season, mosquitoes are more prevalent in December. It's highly recommended to bring a strong insect repellent, preferably one with DEET. Consider wearing lightweight long-sleeved shirts and pants in the evenings, especially if you're exploring areas near standing water.
Absolutely! Many outdoor activities are still very much on. Waterfalls are at their most impressive, and rice paddies are vibrantly green. Surfing conditions can vary; the west coast might be choppier, while the east coast can offer good waves. Be mindful of potential muddy trails for hiking and always check local conditions.
Heavy rain can sometimes cause localized flooding or make roads a bit more challenging to navigate, especially for scooters. Allow extra time for travel, and if riding a scooter, exercise extreme caution. Taxis and ride-sharing apps are readily available and a good option during heavy downpours.
