Let's get down to the nitty-gritty: the average temperature in Jakarta during December typically hovers around 27°C to 28°C (81°F to 82°F). It's generally hot and humid year-round because of its location near the equator. Because of the high temperatures, it feels even warmer, with the humidity levels often exceeding 80%. This means you'll probably be sweating, but hey, that's just part of the experience! This kind of weather calls for light, breathable clothing. Think cotton, linen, and anything that dries quickly. You might want to skip the jeans, which can be super uncomfortable when wet. While the heat is pretty consistent, it's the rainfall that really defines December in Jakarta. You can expect to see rain on a lot of days, with an average of around 15 to 20 rainy days throughout the month. The rain can range from a light drizzle to a downpour, so be prepared for anything. You'll likely experience a mix of sunshine and rain. The sunshine hours will vary, but expect shorter periods of sunshine compared to the dry season, so plan your outdoor activities wisely! The humidity is high, making the air feel heavy. Make sure to stay hydrated, and take breaks from the heat when you need them. The best way to be ready for the December weather is to pack versatile clothing. Bringing things like raincoats, umbrellas, and waterproof bags is crucial, which we will get into later. Also, make sure to consider indoor activities and plan for some downtime, so you have options for those rainy days. Remember that this information is based on averages, and the actual weather can vary from year to year. Now that we have that figured out, let's explore some more specific aspects.

Average Temperature and Humidity in December

Okay, guys, let's talk about the temperature and humidity because they go hand in hand! As mentioned before, Jakarta in December is generally hot. The average high temperature sits around 30°C to 31°C (86°F to 88°F), while the average low is about 24°C to 25°C (75°F to 77°F). Evenings are still warm, so you won't need anything more than a light jacket or sweater. However, the real story here is the humidity. Jakarta is known for its high humidity, and December is no exception. Because of this, it feels even hotter than it actually is. Humidity levels often peak above 80%, which can make the air feel thick and sticky.

Why does it get so humid? Jakarta's location plays a huge role. It's close to the equator and surrounded by water, which contributes to the high moisture levels in the air. The monsoon season also brings in moist air from the Indian Ocean, further amplifying the humidity. This combination creates a unique climate that you'll definitely feel when you step outside! You'll need to stay hydrated. Make sure to drink plenty of water throughout the day to avoid dehydration. Bring breathable clothes. Pack loose-fitting, light-colored clothing made of materials like cotton or linen. These fabrics will help you stay cool and comfortable. Plan indoor activities. Have some backup plans for rainy or extremely humid days, such as visiting museums, shopping malls, or enjoying a spa day. Take breaks. Don't push yourself too hard in the heat. Take breaks in air-conditioned spaces to cool off and recharge. Use air conditioning. Make the most of air conditioning in hotels, restaurants, and other indoor spaces. The combination of high temperature and humidity can be tough, but with the right preparation, you can handle it! Always make sure to check the weather forecast before you head out for the day, and be flexible with your plans. Understanding the temperature and humidity will help you get ready. Now, let's see what else you can get prepared for.

Rainfall and Precipitation Levels in December

Alright, let's get into the rain. December is part of the wet season in Jakarta, so you can expect a good amount of rain. On average, you can expect rain on about 15 to 20 days throughout the month. This doesn't mean it will rain all day every day. Often, you'll see short, heavy downpours that might last for an hour or two. Sometimes, it will be a light drizzle that lingers for a while. The total rainfall amount varies from year to year, but you should anticipate a significant amount. This means it is very important to get ready! The rainiest days usually happen in the afternoon or evening. It's less common to have rain all day long. This is great for planning your activities, because you can schedule outdoor adventures for the mornings and then hit up indoor places in the afternoons.

How heavy is the rain? The intensity of the rain can vary. You might experience a light shower or a torrential downpour. Sometimes, the rain will be accompanied by thunderstorms, so you can expect some lightning and thunder, too. Flash floods are a possibility in some areas, especially in places with poor drainage. Be sure to stay updated on the weather forecast and any alerts issued by local authorities. What causes all this rain? The monsoon season is the main culprit. Strong winds bring moist air from the Indian Ocean, leading to heavy rainfall across the region. Jakarta's proximity to the equator also contributes to the high precipitation levels. Because of the intensity of the rain, bring some waterproof gear, and consider bringing a waterproof backpack to keep your electronics and other valuables safe. Check the weather forecast daily. This will give you a good idea of what to expect each day. Be flexible with your plans. Have backup plans ready in case it rains. Plan your outdoor activities. Schedule your outdoor adventures for the mornings, when the weather is usually more favorable. Now, let's move on to the sunshine hours.

Sunshine Hours and Daylight in Jakarta during December

Let's talk about sunshine, guys! Even though December is part of the rainy season, you'll still see the sun. However, the sunshine hours are shorter compared to the dry season. You can expect around 5 to 6 hours of sunshine per day on average. This means the days are still pretty long, but you might not get as much uninterrupted sunshine as you'd hope for. The sun rises around 6:00 AM and sets around 6:00 PM. This gives you roughly 12 hours of daylight to enjoy the city. The amount of sunshine can vary. Some days will be bright and sunny for most of the day, while others will be cloudy or overcast with rain. Because of this, it's useful to have some plans for both scenarios. The weather changes in Jakarta can be unpredictable. You might experience a mix of sunshine, clouds, and rain all in the same day. This is totally normal, so don't be surprised if the weather keeps changing.

How to make the most of the sunshine: Schedule outdoor activities for the mornings. The mornings are usually the sunniest and driest part of the day, so plan your outdoor adventures for this time. Take advantage of sunny spells. When the sun is out, make the most of it! Visit parks, explore outdoor attractions, or simply enjoy a walk around the city. Be prepared for clouds. Be prepared for cloudy days by having indoor activities in mind. Consider bringing a hat, sunglasses, and sunscreen. Even on cloudy days, the sun can still be strong, so protect yourself from UV rays. Enjoy the sunsets. Jakarta has some beautiful sunsets, especially when the clouds are just right. Find a good spot and watch the sunset over the city skyline. Now that we have the sunshine talked about, let's talk about some useful tips and advice.
