Inspired?Indonesia in August is all about island-hopping and beach adventures. You'll have plenty of sunshine to bask in, perfect for snorkeling, diving, or simply lounging in the sand. That said, you’ll want to be ready for crowds and potentially higher prices. Here’s our guide to the weather in Indonesia in August.
Created by local experts
If you're planning to visit Indonesia in August, you're in for a treat with its reliably dry and sunny weather, characteristic of the dry season.
Rainfall in August remains minimal across many regions, typically averaging less than 50 mm. This low precipitation ensures that your outdoor plans are unlikely to be disrupted by rain, allowing you to make the most of your trip.
Humidity levels are also relatively low, and the climate can be quite comfortable. This is the best weather you could ask for for outdoor activities such as hiking, beach outings, and sightseeing.
August falls within Indonesia's high tourism season, drawing crowds due to the combination of perfect weather and international holiday periods. You can expect popular attractions to be bustling, with accommodations and flight prices reflecting the heightened demand.
However, the vibrant atmosphere, numerous festivals, and cultural events might be worth putting up with the crowds for.
Overall, August can be a great time to visit Indonesia, thanks to its dry, sunny weather ideal for a wide range of activities. While it's the high season with increased tourist traffic, the delightful climate and lively ambiance make it an appealing time to take a trip.
Daytime temperatures typically reach around 30°C (86°F), providing warm and sunny conditions ideal for outdoor activities, sightseeing, and beach excursions. At night, temperatures cool to approximately 24°C (75°F).
Sea temperatures remain invitingly warm, averaging around 27°C (81°F), perfect for swimming, snorkeling, and diving.
Jakarta and Java experience warm and relatively dry weather in August, with daytime temperatures averaging around 31°C (88°F). The humidity levels remain moderate, and rainfall is minimal, making it an ideal month for exploring Java without the inconvenience of rain showers.
In August, Bali and the Lesser Sunda Islands, including Lombok and Flores, enjoy temperatures ranging from 26°C to 31°C (79°F to 88°F). The islands experience very little rainfall, with sunny days prevailing throughout the month. Humidity levels remain low, creating perfect conditions for tourists to relax on the beaches, visit temples, or engage in watersports with clear skies and warm temperatures.
Sumatra in August sees temperatures between 25°C and 30°C (77°F to 86°F). Coastal areas like Medan and Padang continue to experience dry and warm weather, with minimal rainfall. Inland regions also enjoy favorable conditions for exploring Sumatra's natural landscapes, including its rainforests and volcanic terrain, under sunny skies.
Papua and eastern Indonesia, including Sulawesi and the Moluccas, have temperatures ranging from 27°C to 32°C (81°F to 90°F) in August. The region remains dry with very little rainfall, creating hot and humid conditions.
August is the peak tourist season for Indonesia for a reason. Weather-wise, this month offers a fantastic opportunity to see Indonesia during its dry season. Most of the archipelago is sunny with minimal rainfall, which is ideal for temple hopping at places like Borobudur or simply lounging on Indonesia’s stunning beaches.
Meanwhile, Sumatra and Kalimantan might see occasional showers, which is perfect for exploring lush rainforests and experiencing their vibrant greenery.
If you are hoping for a beach getaway, you will love the warm waters around the Gili Islands or the marine wonders of Raja Ampat in August. Culturally, August is vibrant with events like Bali's Independence Day celebrations, offering a glimpse into local traditions.
This can also be a great time of year for climbing volcanoes such as Mount Bromo or discovering unique wildlife in Komodo National Park. Whether you're into sun-soaked relaxation, cultural experiences, or thrilling expeditions, Indonesia in August promises an unforgettable trip.
One of the downsides of visiting in August is that this time of the year is the peak tourist season, especially in hotspots like Bali, Jakarta, and Yogyakarta. This month is a magnet for international and domestic travelers, thanks to school holidays and summer vacations in many countries. You can expect packed beaches, busy tourist attractions, and cultural sites buzzing with activity. Planning ahead is key to managing the crowds and queues at popular spots.
Accommodation costs are going to be on the higher side. With the surge in demand, hotels and resorts, particularly those near beaches, hike up their rates. If you're after a more budget-friendly trip, you might want to consider visiting during the shoulder months like April, May, or September. You’ll enjoy similar weather to August but without the throngs of tourists. Plus, accommodation prices drop, making it a more relaxed and affordable experience.
That said, if you're chasing guaranteed sunny days and a vibrant atmosphere, August won’t disappoint, despite the higher expenses.
Still haven't decided where you're going this summer? Explore our list of the best August holiday destinations.
