May is the beginning of the dry season when Indonesia transitions from a long, wet winter into summer. The weather is sunny and beautiful—with occasional scattered showers— and tourists begin arriving again. The white sand beaches along Bali’s southern coast are idyllic and still fairly uncrowded, and the volcanos on Java, Lombok, and other islands are finally in the perfect condition for climbing.
## Weather in Indonesia During May: A Comprehensive Guide
May in Indonesia heralds the official commencement of the dry season, a welcome transition after the wetter months. While you might still encounter sporadic showers, particularly in the early part of the month, these are generally less intense and of shorter duration compared to earlier in the year, especially around Bali. Packing a light raincoat is advisable, although you may find you don’t need it on most days. The overall trend is towards drier and sunnier conditions.
Temperatures are consistently warm, with abundant sunshine and clear blue skies predominating. Bali typically experiences temperatures ranging from a comfortable 86°F to 90°F, creating an ideal climate for exploring its beaches and cultural sites. East Java, on the other hand, tends to be hotter, with average temperatures soaring to between 95°F and 97°F. This makes it essential to stay hydrated and seek shade during the hottest parts of the day. Evenings remain pleasantly warm, particularly in Bali, where nighttime temperatures rarely dip below 87°F to 90°F. Java offers slightly cooler evenings, with average temperatures ranging from 68°F to 70°F. To ensure a comfortable trip, be sure to pack plenty of sunscreen, lightweight and breathable clothing suitable for hot weather, and remember to drink plenty of water to avoid dehydration.
## Crowd Levels and Travel Costs in May
As May progresses, the number of tourists visiting Indonesia starts to increase. However, it’s not yet the peak season experienced in the middle of summer, when popular beaches become crowded and competition for tables at restaurants and bars intensifies. Bali, being the most popular island destination, naturally attracts the largest crowds. In contrast, more remote locations like the Moluccas or Raja Ampat offer a more secluded experience with significantly fewer tourists. If you prefer tranquil escapes and untouched natural beauty, these destinations should be high on your list.
Regarding costs, May marks a transition period for airlines and hotels, with many beginning to implement their high-season rates. While it might still be possible to find some deals with diligent searching, prices overall will generally be higher compared to the lower rates available during the wet season. Booking flights and accommodations in advance is highly recommended to secure the best possible prices.
## Ideal Destinations to Visit in Indonesia During May
Virtually every corner of Indonesia offers unique and rewarding experiences in May. Bali, for instance, presents an appealing combination of warm, sunny weather, stunning beaches, crystal-clear waters, and relatively smaller crowds compared to the peak summer months. You can enjoy popular attractions like Kuta, Ubud, Tanah Lot, and other frequently visited spots without having to navigate through overwhelming throngs of people.
Furthermore, May is an excellent month for mountaineering enthusiasts to conquer any of the country’s numerous mountains and volcanoes. With drier conditions, these peaks become more accessible and offer breathtaking views. Among the many options available are Mt. Bromo and Mt. Ijen in Java, renowned for their spectacular sunrises and unique volcanic landscapes, as well as Mt. Rinjani in Lombok, a challenging but rewarding climb with stunning crater lake views.
Consider venturing to the islands of Nusa Tenggara, Flores, or Sumba, where you can expect dry and sunny weather, pristine beaches, and a wide array of outdoor activities. Diving off the coast of Lombok is an unforgettable experience, showcasing vibrant coral reefs and diverse marine life. It’s also a perfect time to explore Komodo National Park, home to the iconic Komodo dragons.
Sumatra presents another compelling option. Temperatures typically range from a pleasant 80°F to 83°F, making it ideal for relaxing on the beach, exploring ancient temples, and immersing yourself in the rich cultural heritage of the island.
However, it’s worth noting that Kalimantan experiences a light rainy season from March to May, making it one of the few islands that might not be as ideal for a visit during this particular month.
## Activities and Experiences to Enjoy in Indonesia
In Bali, surfing at Kuta beach is a classic activity, while shopping and dining in Sanur offer a more relaxed atmosphere. For adrenaline junkies, Tanjung Benoa provides a range of thrilling water sports, including jetpacks that allow you to soar above the water. The southern part of the island is replete with beach activities such as snorkeling, scuba diving, sea kayaking, and other ocean adventures. Further north, a visit to Ubud allows you to interact with Balinese long-tailed monkeys at the renowned Monkey Forest (Mandala Suci Wenara Wana), where they eagerly approach tourists in search of bananas and other treats.
Consider trying a meditation session or taking a yoga class at the Yoga Barn, a popular wellness center in Ubud. Alternatively, take a trip to the silversmiths in a Celuk village just outside of town, where you can witness the intricate craftsmanship involved in creating beautiful silver jewelry. From there, you can continue north to Bedugul to explore destinations like the Bali Treetop Adventure Park or the Bali Botanic Garden.
In Java, challenge yourself with a climb up Mt. Bromo or Mt. Ijen. If volcanoes are not your preference, explore the sacred Borobudur Temple complex near Yogyakarta or the Candi Prambanan complex located nearby. For a taste of city life, visit Surabaya, the second-largest city in the archipelago, and delve into its diverse culinary scene, shopping districts, and entertainment options.
In Sumatra, visit the Mesjid Raya Al Mashun mosque in the northern city of Medan or explore Istana Maimun, a royal palace that once belonged to the Sultanate of Deli. Alternatively, head south to Palembang, also known as the “Venice of the East,” and visit the Great Mosque of Palembang or take a scenic Musi River cruise.
## Events and Festivals in May
**Waisak Day:** Also known as “Buddha Day,” this significant Buddhist holiday is celebrated throughout Asia. The festival, which commemorates the birth, enlightenment, and death of Buddha, takes place on a full moon, typically in early to mid-May (although it can occasionally fall in April). Thousands of monks gather in the town of Borobudur to chant in a ritual called “Pradaksina” that involves transporting holy water and flames. This is a truly remarkable event to witness, offering a glimpse into the deeply rooted spiritual traditions of Indonesia.
